Installed the Angular CLI using this command
npm install -g #angular/cli
But when creating new project using command
ng new PROJECT-NAME
it shows
You are running version v8.0.0 of Node.js, which is not supported by
Angular CLI v6. The official Node.js version that is supported is
8.9 and greater. Please visit https://nodejs.org/en/ to find instructions on how to update Node.js.
But actually i am using nodejs v9.11.1
See screenshot of my cli
Mostly sounds like a version problem. The new angular cli version requires the latest version of node.
All you need to do is update node and npm to latest version , everything should work fine.
If you are working on windows I'd suggest just going on their site and getting the latest one(currently at the time of this post is 8.11.2). For linux based and mac I would suggest looking for a guide how to get latest version since installing from terminal with something like (apt-get install or yum) will not have latest version you need (can easily be changed with some simple commands)
Also do check the version of node with: node -v
There has also been a naming conflict on linux regarding node vs nodejs see this question.

I am building a sample application in which I need to use Node Version v9.11.2 and npm 4.0.0. Currently I have Node Version v16.4.0 installed on my system. I tried to install the specific version by uninstalling the latest version and installing version 9.11.2 from official website
Problem: The problem is I can uninstall the latest version without any problem but when I try to install older version(9.11.2) the command gets opened and it does nothing. I also tried to install the older version using cli commands ie. npm install -g node#9.11.2, it installs the version but on checking the version using node -v, it still shows the latest version(16.4.0)
Below are the screenshots for better understanding
Installed version 9.11.2 but showing 16.4.0
Any Solution please ?
Is using docker a possibility? If so you can simply get a docker image of the required version and use if from there.
Another way is to use NVM which is a really useful tool to manage nodejs versions. I'm including their github repo for your convenience:
https://github.com/nvm-sh/nvm
A good option is to use NVM: https://github.com/coreybutler/nvm-windows (Windows) or https://github.com/nvm-sh/nvm (unix, macOS). With NVM you can enable different versions of node on the same machine and switch from one to another, usually it takes care of managing the installed packages and adding them to its own management system.
I am getting below error when I tried to use ng command
Node.js version v11.13.0 detected.
The Angular CLI requires a minimum Node.js version of either v10.13 or v12.0.
Please update your Node.js version or visit https://nodejs.org/ for additional instructions.
When I try to see the node version using node -v, I see node version on my machine is v12.18.3
So from where ng is getting v11.13.0? How do I resolve this issue?
I tried below steps
Clear the NPM cache
Uninstall both node versions from the NVM
Uninstall anything that starts with node in Control Panel\Programs and Features
Install required node versions in NVM
Install Angular CLI
and things started working for me.
Had the same issue. It turns out installed Angular CLI was not compatible with the installed node and npm version. I used the https://stackoverflow.com/a/60258560 to check the compatibility. Then performed following steps:
Uninstall Angular cli
Uninstall Node and NVM
Installed Node version I wanted (10.x).
Installed specific Angular version corresponding to Node v10 which was Angular Cli v11 at this time.
I was also facing the same issue in my Windows machine where the node -v version and the version picked up by ng command were different. This was because my node.js command prompt was picking the version from AppData\Roaming\npm folder. Cleaning up this folder fixed the issue for me.
Uninstall node
Empty the contents from C:\Users<user>\AppData\Roaming\npm
Install the required node version
Trying to learn angular recently, but I am stuck in an error of angular. So here it is.
I am using Ubuntu 18.04, installed node latest version via nvm.
But I have "two" nodes in Ubuntu,[default] nodejs which is v8 now, and the node v13.
When I try to create angular project with ng new my-first-project it runs good, but it keeps warning of some deprecated dependencies for example core-js. I upgraded core-js to the latest(forced using sudo). But the deprecation warning did not disappear, I thought to use sudo ng new my-first-project but this time it brings me error
You are running version v8.10.0 of Node.js, which is not supported by Angular CLI 8.0+.
The official Node.js version that is supported is 10.9 or greater.
Please visit https://nodejs.org/en/ to find instructions on how to update Node.js.
How can I change angular's using nodejs -> node?
You have two Node.js versions installed with nvm, v8 and v13. It seems that Node.js v8 is active, you can check this with node --version command line command. If the version is really v8 you have to change it with nvm to v13 using nvm use 13.{x.x} command. The {x.x} should be the concrete installed version. If you don't know the installed versions by heart you can check them with nvm list command line command.
If you change the active Node.js version to v13 with nvm it will be used by Angular CLI and you won't get the above mentioned error.
when i run the following command, it shows 6.4.1.
npm run ng --version
but when i am running the following command, it is installing 8.1.0 and getting error. i do not understand how it is happening.
npm install -g #angular/cli
i tried the following commands. but it is not working
npm cache clean --force
npm install -g #angular/cli

My Requirement:
Angular 6
how can i resolve this?
You should the latest (12+) node when upgrading to angular 8. You can download it from here.
After upgrading node, the issues should go away.
For simple use cases and thanks to the work done in Angular 8, you can upgrade to the latest release using one command:
$ ng update #angular/cli #angular/core
After running this command, the lazy loaded routes will be automatically migrated to the new import syntax which is standard compliant and brings Angular close to the open web platform.
You also need to be aware of the following issues when upgrading your project:
Angular 8 makes use of the latest TypeScript 3.4, so even if the upgrade process completes with success you might have some syntax errors that may be due to the better type inference system used by the latest version which detects new potential typing issues but in the end this will improve your code quality and helps you avoid bugs in the future. You can see the new features of TypeScript 3.4 from the official docs.
You need to have Node.js 12+. Simply run node -v to verify your Node version. You can install the latest version from the official website
I have a restriction of using node JS version 6.9.1. I am getting many problems, while using angular cli quick start steps.
after ng serve, browser page will be white, no error in console.
npm start works, but if i change some style/file browser do not not refresh.
if i make any style change, webpack compiled successfully message comes but webserver fails to load page.
When I follow the quick start steps with latest nodejs it works like a charm. Can any one help me in telling, what are the versions (npm, angular-cli), I should use to run it ?

Each Angular/Cli version has limited its compatibility of node versions below a specified release. If you have to use a specific version of node then your best bet would be to find a previous version of the Angular/Cli that will play nicely.
Here you can find all the versions and from there, pick one a little further back in the list and then do a search in google for "Angular/cli version x.x.x node compatibility" to see if there are any known issues.
Once you pick a version that looks good, run
npm install -g #angular/cli#<your version number>.
Once the install is complete run ng help and you'll get feedback right away if the version is still incompatible and you can try a different version.
Just make sure you get rid of the installs you aren't using with npm uninstall -g #angular/cli#<your version number>
for see if angular-cli is compatibility whit your node version installed you can see https://www.npmjs.com/package/#angular/cli/v/6.0.8?activeTab=versions, for example, I have installed node 6.11.2 and I have to use: npm install -g #angular/cli#6.0.0
