I am trying to install angular cli on Windows 10, I have already installed npm and node, and have verified their version, they are above then what is required for angular cli to install but when I run install command on the prompt it show error.

i have uninstalled npm and node, then reinstalled them, and tried again to install and it worked :) thanks

first try to see node and npm is installed successfully using following commands on cmd
node -v
for node and it will return the version of node,then
npm -v
then it will return the version of npm after that in windows go to environment variables and see node environmental varible is there. after that

ng: command not found after installing node and angular cli

I just got a new clean MacOS Catalina installation, and I was trying to get my old project running using ng serve but it tells me that 'ng: command not found' I installed the npm 6.12.1 through nodeJS 12.13.1 installation as well, and ran 'npm install -g #angular/cli' and both ran without issues, then ran the npm i command for the stuff included in package.json in the same project directory, I googled around and one comment suggested using npm link #angular/cli which didn't differ as well

Problems installing Vue js

I am trying to install vue.js with no success, yet npm is up to date.
When I run vue init webpack vueapp I get this error:
No command 'vue' found, did you mean:Command 'vpe' from package 'texlive-latex-extra' (universe)
vue: command not found
I have already installed the cli using npm install vue-cli.
Thanks
Try to use npm install -g #vue/cli and then vue ui to start client in your browser.
You'll want to use npm install -g #vue/cli. Restart your terminal to make sure it shows up.
Also, make sure you have node 8.9+
From the docs:
Warning regarding Previous Versions
The package name changed from vue-cli to #vue/cli. If you have the previous vue-cli (1.x or 2.x) package installed globally, you need to uninstall it first with npm uninstall vue-cli -g or yarn global remove vue-cli.
Node Version Requirement
Vue CLI requires Node.js version 8.9 or above (8.11.0+ recommended). You can manage multiple versions of Node on the same machine with nvm or nvm-windows.
For me sudo helps to solve it.
Try to use this command in terminal:
sudo yarn global add #vue/cli
Then you can check the version and all will work correctly.
vue --version
Have you installed view?
Can you check vue --version
https://cli.vuejs.org/guide/installation.html
Try to use sudo npm install -g #vue/cli instead of npm install -g #vue/cli
You need to use sudo.
The vue-cli documentation at https://cli.vuejs.org/guide/installation.html states that:
To install the new package, use one of the following commands. You
need administrator privileges to execute these unless npm was
installed on your system through a Node.js version manager (e.g. n or
nvm).
npm install -g #vue/cli
# OR
yarn global add #vue/cli
Just run npm install -g pnpm for the missing packages.
Then you can run npm install -g #vue/cli
Now you can ckeck the vue --version
sudo npm install -g #aws-amplify/cli --unsafe-perm=true
It works for my situation.

Your global Angular CLI version (6.0.8) is greater than your local version (1.0.2)

C:\dev\myApp> ng serve -o
Your global Angular CLI version (6.0.8) is greater than your local version (1.0.2).
The local Angular CLI version is used.
To disable this warning use `"ng config -g cli.warnings.versionMismatch false"`
I don't know what to do with this.
I tried uninstalling angular/cli and npm cache clean but still have problems.
Anyone help me !
You have the old angular/cli package in your package.json
To update use:
npm r angular-cli
npm i #angular/cli#latest -D
Be aware though, if you have already been using the old cli for a long time, you might have to do some code migration. Especially when it comes to tests, polyfills and the angular config file.
You could try to create an empty angular project using the new cli, and compare the files which are created there, with the files you have in your own project, and update where applicable.
After that, when you have to update your cli again, you can use the new ng update command
You are using new project in older CLI you need to run this commands
npm uninstall --save-dev angular-cli
npm install --save-dev #angular/cli#latest
npm install
or you can try this approach
Updating npm :
Run [sudo] npm install -g npm (sudo is only required on Mac/ Linux)
Updating the CLI :
[sudo] npm uninstall -g angular-cli #angular/cli
npm cache clean
[sudo] npm install -g #angular/cli
i have try all command above but, it don't work. Maybe you can try this command for same probblem. it work for me.
ng update #angular/cli #angular/core
npm uninstall --save-dev angular-cli
npm install
if it still problem you can visit : https://angular.io/cli/update
and you can choice "Angular Update Guide" for specify version update from X to X

npm WARN npm npm does not support Node.js v9.1.0

I updated to the latest node v9.1.0 and now npm doesn't work.
npm WARN npm npm does not support Node.js v9.1.0
It turns out that the current installed npm is not compatible with the new node and has a hard time updating.
The solution is to uninstall npm and then reinstall node which will contain the correct version of npm.
Here's how:
Uninstall npm.
Mac:
sudo npm uninstall -g npm
Windows:
npm uninstall -g npm
Install node from https://nodejs.org
Uninstall the global instance of npm:
npm uninstall -g npm
This will cause your system to fall back on the version of npm installed by node 9.1.0 and the warning will disappear.
What worked for me was to delete npm and npm cache from C:\Users\chrisd\AppData\Roaming
Then I ran npm i -g npm#next for the latest version of npm for Node 9.x
NPMJS.org has issued a new release 11.27.2017 -- npm v5.6.0
(You may not have to delete the npm/npm cacheif you just upgrade, but I had already done that before finding the new release)
NPMJS Release notes
Fixed my issue update to 5.71
npm uninstall -g npm
npm i -g npm#next
Had similar issue in linux/ubuntu, below helped solving it.
Remove existing versions of npm and node:
sudo apt --auto-remove purge npm
sudo apt --auto-remove purge nodejs
Re-install node
for me worked
npm uninstall -g npm
npm i -g npm#next
No need for manual installation or clearing the cache.
Run with admin credentials if needed.
I saw this warning after I upgraded to Node 10.4.1 after that I just ran npm uninstall -g npm with -g flag to remove it globally and the error was gone. I guess it updated my npm to version 6.1.0
Solution :
Go to the path where you can find the debug log (this file is found in your npm-cache folder) C:\Users\yourname\AppData\Roaming
Delete the NPM and NPM-Cache folder, but DO NOT reinstall node. Once deleted go back to your command line and re-use the command " npm install -g npm#latest "
What worked for me - On Ubuntu
Install nodejs
sudo apt install nodejs
Install npm
curl -L https://www.npmjs.com/install.sh | sudo sh
If you are unable to uninstall npm, instead you can skip that step and just
Reinstall npm https://nodejs.org/en/
This error occurs when the npm version not compatible with the node version. However npm uninstall -g npm also gives the same error for me.
So following steps work for me.
Option 1:
Step1: Follow this directory
C:\Users(your username)\AppData\Roaming
Step2: Delete the npm folder. And if there is a folder called `npm cache, delete it also.
Step3: Run npm clean cache —force ( — force is now required to clean cache)
If the above option is not worked for you please follow the below steps.
Option 2:
Follow this directory
C:\Users(your username)\AppData\Roaming
Delete the npm folder and if there is one mom cache folder.
Run npm clean cache --force ( -- force is now required to clean cache)
Make sure everything to do with Nodejs is deleted and uninstalled.
Reinstall Nodejs.
I had the same issue with npm when I have updated Node js on windows. I tried many things but only working solution was :
First uninstall npm with below command
npm uninstall -g npm
Now Install latest version
npm install npm#latest -g
If you are using Mac and brew, that's how I've got rid of this problem:
Even though I installed and reinstalled node with brew, with last version 11.8.0, apparently it kept using the last version
fdecollibus$ npm install --global gatsby-cli
npm WARN npm npm does not support Node.js v11.8.0
npm WARN npm You should probably upgrade to a newer version of node as we

+ gatsby-cli#2.4.8
npm -v gave me back version 5.6.0. I've therefore noticed that /usr/local/lib/node_modules had wrong permissions assigned to root:wheel.
A chown did not fix the problem: I've had to manually delete the content of the folder (cd /usr/local/lib/node_modules and -careful - type rm -rf * ) to get rid of the folder.
Then I've run brew uninstall node and again brew install node, and finally npm -v gave me back 6.5.0
Executing npm uninstall -g npm gave me same error
Uninstall Node.js installed in the system
Goto c:\Program File\nodejs (default location of the nodejs installation). Remove all contents of the folder manually.
Remove npm, npm-cache folder from Roaming folder under your username.
Install Node.js again.
running npm install #angular/cli -g worked for me.
I was getting the below warning when I executed, npm install to install package.json for my angular project.

According to #Ilyich, I uninstalled global npm, npm uninstall -g npm
And then I executed npm install to install my package, it installed successfully.
Navigate to the Appdata by typing %AppData% in the run or search.
Delete the npm and npm-cache folder and then install the nodejs again. It solved the issue for me.
If you are getting the same warnings while creating or importing an Angular project in an IDE such as Eclipse ,do the following:
File->New->Angular
In the window that appears change the versions of Nodejs and NPM to "use system installation"
...
If the process crashes at "installing packages for tooling via npm"
Close the terminal in IDE and manually go to the project directory and do "npm install".
Refresh the project in IDE
I had a similar issue trying to install other stuffs.
And looks like the npm version was not compatible with my node version.
In my case i had npm 5.4.2 and node v10.15.0
At the end of this process i had the version npm 6.7.0 and node v10.5.0
First Option:
I downgrade the version of node and other tools.
On terminal execute the next command with the version to be installed. (Example if we need change to node 8.14.1)
1.- Npm install -g node#8.14.1
Then we execute the command to uninstall the version to be removed.
2.- Npm uninstall -g node#8.15.0
After that we need execute the next command to set the new path
3.- Npm update -g node#8.14.1
Finally we only need execute the version to see if the changes were added successfully
4.- Node -v
In this case we will see the version as 8.14.1 and we finished the process.
If you want do it for Appium and Npm version you can open a new terminal and follow the same steps in order to change the version. For example:
Npm install -g appium#1.7.2
Npm uninstall -g appium#1.10.0
Npm update -g appium#1.7.2
Appium -v
In my case you must have the next versions:
Node 8.14.1
Npm 6.4.1
Other Way:
To solve it i just execute in the terminal the next line.
curl -L https://npmjs.org/install.sh | sh
After download a few files (took around of 10 minutes to see results in the terminal) i was able to continue working with the new latest and compatible version of both tools.
The next WARM was displayed in this case.

I am on a macOS and what ended up working for me was uninstalling npm, relinking Node, and reinstalling Node through Homebrew. (Prereqs: Have Homebrew installed and have a very confusing setup where npm and Node don't work together)
1. To uninstall homebrew:
If you are on a Mac, you probably don't see the AppData\Roamingfolder; you should instead go to npm root -g and delete the npm_modules folder. Now, when you type npm --version your computer should be confused.
2. Reinstalling node:
Try doing brew install node and if you already have node installed, your computer will ask you to reinstall it. If you do brew reinstall node and your versions of brew and npm look good, then you don't need to do the last step!
3. If you need to link the correct version of Node:
This step was something I think was my fault since I think I had installed Node through Homebrew as well as the actual online download. Follow the suggestions after brew link node which should take you to brew link --overwrite node. There will be around 7 directories that the command will not be able to overwrite, which you should all delete using sudo rm -rf directory_name. (Do use your common sense, don't delete something important.) After you are finally able to run the brew link --overwrite node command without any errors, you should then do brew reinstall node since you don't have npm anymore.
Tada! You hopefully now have version of npm and node that hopefully can work together.
Just install latest version of Node.js from https://nodejs.org
This will automatically update npm for you
Easiest way I found was to install the latest node with brew and the latest npm manually:
brew uninstall node
brew install node
npm install -g npm#latest
This removed the warning message. For some reason brew wasn't linking the new npm installed by node while it was updating node itself.
The easiest way(for windows) is to use the installer to remove node, then use it to reinstall node, at which time it will install the correct version of npm. running the above uninstall commands does not work, since the wrong version of node is installed, otherwise you wouldn't have this issue.
You can uninstall node current version, and install a early version that support npm. Then run npm install npm#latest -g and install current node version.
It's work for me
lowering the npm version worked for me (windows 10):
npm i npm#6.14.11
To upgrade the npm and Node:
Step 1. Uninstall the npm:
Mac: `sudo npm uninstall -g npm`
Windows: `npm uninstall -g npm`
Step 2: Install the latest version of Node: https://nodejs.org/en/

Cannot uninstall angular-cli

I've tried several times to uninstall my angular-cli in order to update it but even if I follow the instructions provided on github:
npm uninstall -g #angular/cli
npm cache clean
npm install -g #angular/cli#latest
When I check using the command ng --version I still get the old version :
angular-cli: 1.0.0-beta.26
node: 7.7.1
os: darwin x64
How can i fix this issue? Thanks
I have also faced the same issue in recent past for me I have do the following commands one by one in terminal.
sudo npm uninstall -g angular-cli
sudo npm cache clean
After this run
ng -v
If still get angular-cli version 1.0.0-beta.2x.x then run the following command
which ng
It will show the ng path. Go to the path and if it is linked with any file remove the same the link and actual ng file. In my case the link is in /usr/bin/ng and actual path of ng file is /lib/node_modules/#angular/cli/bin/ng.
sudo rm -rf /lib/node_modules/#angular/cli/bin/ng
sudo rm -rf /usr/bin/ng
Next you need to install #angular/cli using
sudo npm install -g #angular/cli
Close all the terminal and run ng -v and you are on. May be it will help someone. Thanks :)
If you are facing issue with angular/cli then use the following commands:
npm uninstall -g angular-cli to uninstall the angular/cli.
npm cache clean to clean your npm cache from app data folder under your username.
use npm cache verify to verify your cache whether it is corrupted or not.
use npm cache verify --force to clean your entire cache from your system.
Note:
You can also delete by the following the paths
C:\Users\"Your_syste_User_name"\AppData\Roaming\npm and C:\Users\"Your_syste_User_name"\AppData\Roaming\npm-cache
Then use the following command to install latest angular/cli version globally in your system.
npm install -g #angular/cli#latest
To get more information visit github angular-cli update.
Updating Angular CLI
https://github.com/angular/angular-cli#updating-angular-cli
If you're using Angular CLI 1.0.0-beta.28 or less, you need to uninstall angular-cli package first.
npm uninstall -g angular-cli
npm uninstall -g #angular/cli
npm cache clean
npm install -g #angular/cli#latest
Then when it gets done successfully you may try:
ng --version
This sometime happens when you had actually installed #angular/cli using yarn and not npm.
You can verify this by looking in to yarn's global install folder.
You can remove it from yarn using
yarn global remove #angular/cli
You are using the beta version of angular CLI you can do this way.
npm uninstall -g #angular/cli
npm uninstall -g angular/cli
Then type,
npm cache clean
Then go to the AppData folder which is hidden in your users and go to roaming folder which is inside AppData then go to npm folder and delete angular files in there and also go to npm-cache folder and delete angular components in there.After that restart your PC and type
npm install -g #angular/cli#latest
This worked for me ✌️
I found a solution, first, delete the ng file with
sudo rm /usr/bin/ng
then install nvm (you need to restart your terminal to use nvm).
then install and use node 6 via nvm
nvm install 6
nvm use 6
finally install angular cli
npm install -g #angular/cli
this worked for me, I wanted to update to v1.0 stable from 1.0.28 beta, but couldn't uninstall the beta version (same situation that you desrcibed).
Hope this works
The following approach worked for me:
npm uninstall -g #angular/cli
and
npm cache verify
I had the same problem. This doesn't work:
npm uninstall -g angular/cli
npm cache clean
instead use:
npm uninstall -g # angular/cli
I could not get the angular-cli to go away. I FINALLY figured out a way to find it on my windows machine. If you have Cygwin installed or you are running linux or mac you can run which ng and it will give you the directory the command is running from. In my case it was running from /c/Users/myuser/AppData/Roaming/npm/ng
I had angular-cli version 1.0.0-beta.28.3, and the only thing that worked for me was deleting the angular-cli directly from the global node_modules folder:
cd /usr/local/bin/lib/node_modules
rm -rf angular-cli
After that ng version output was, as expected:
command not found: ng
And I could install the latest angular-cli version:
npm install -g #angular/cli#latest
Hope it helps...
Step 1:
npm uninstall -g angular-cli
Step 2:
npm cache clean
Step 3:
npm cache verify
Step 4:
npm cache verify --force
Note:
You can also delete by the following the paths
C:\Users"System_name"\AppData\Roaming\npm and
C:\Users"System_name"\AppData\Roaming\npm-cache
Then
Step 5:
npm install -g #angular/cli#latest
You have to use (without #)
npm uninstall -g angular/cli
because
If you're using Angular CLI beta.28 or less, you need to uninstall angular-cli package. It should be done due to changing of package's name and scope from angular-cli to #angular/cli https://github.com/angular/angular-cli
Try to update via these steps found in the npm repo for the angular cli.
npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli#latest
There is also an angular cli migration guide. One other option (more involved) is to start a new project and migrate over by copying and pasting certain files. This can be found here in the "moving into the cli" section of the angular-cli github
Check if you have the hidden folder ".npm" in your Home directory and delete the old angular-cli folder.
While uninstalling Angular CLI I got the same message (as it had some permission issues):
Unable to delete .Staging folder
I tried deleting the .staging folder manually, but still got the same error. I logged in from my administrator account and tried deleting the staging folder again manually, but to no avail.
I tried this (run as Administrator):
npm uninstall -g #angular/cli
npm cache verify
npm install -g #angular/cli.
Then I tried creating the project from my normal user account and it worked.
For those using Windows, I had this issue because :
after running npm uninstall -g # angular/cli, the folder AppData\Roaming\npm were still containing a ng file
this file prevented a complete uninstall of the CLI
I tried then to remove the ng file manually, but for some reasons it was not possible (I did not have the right), even as admin.
The only hack I found was using a 'linux based' command (I used Git bash) as admin and removing this file from command line:
cd AppData/Roaming/npm
rm ng.cmd
For information: this was with the version 6 of the CLI. There is not problem anymore to remove manually this specific file after the update.
