How to delete node installed by brew completely? - node.js

I have a problem with uninstalling 'node' with brew.
When I used
brew uninstall node
, it showed:
Uninstalling /usr/local/Cellar/node/7.8.0... (3,076 files, 39.9MB)
; but when I commanded:
node -v
, there is still
v6.9.4
When I tried to use brew uninstall node again, it showed:
Error: No such keg: /usr/local/Cellar/node
I think I installed node package before, and today I used a wrong command:
brew install nodejs
while I actually wanted to install node. And then I found I was wrong, so I also uninstalled nodejs in the same way. But node package with lower version is still there. Anybody knows why and can help me delete it completely and reinstall?

Sounds like you may have installed node via another method in the past.
If you do
$ ls -la $(which node)
It should tell you where it's installed (and if that's symlinked to another location or not).
Removing that binary is part of the thing, the other thing you'll want to do is remove the root npm and the node_modules folder.
Find npm the same way as you found the node binary, but the root node_modules folder is probably either under /usr/local/lib but might be elsewhere; you can check npm config ls -l to get a list of all the settings of npm, which will tell you what directories to look in are.

I went through the process of
I went through the process of removing all traces of Node and npm from my own installation as npm was corrupted (was mishandling vulnerabilities), and now want to install it using brew, or in some other way so all the errors with npm when attempting to npm install don't occur. Why does brew have node installed even though I didn't install it?
Those files are not NodeJS itself, but are the instructions that tell Homebrew how to install NodeJS. You can remove those formula (along with any others that are not being used) with brew cleanup.
Edit: You cannot actually remove the formulae since those are needed if you were to install it at a later point.

Updating to stable version of nodejs with n

this is my first time trying to update the nodejs version of a unix server. I want to use it to create a react app, and facing the following:
>npx create-react-app test
You are running Node 8.11.3.
Create React App requires Node 10 or higher.
Please update your version of Node.
So I have tried to update the version with the following commands:
>sudo npm cache clean -f
>sudo npm install -g n
>sudo n stable
installed : v14.15.4 to /usr/local/bin/node
active : v8.11.3 at /bin/node
However it seems that didn't upgrade the version, it installed a different version in a different path.
I am not sure if it is possible just to upgrade the version that is already active, I prefer not to do a workaround and just upgrade it directly.
As complementary information if I run n doctor I see the following:
>n doctor
Checking n install destination is in PATH...
'/usr/local/bin' is not in PATH
As I said previously, what I am looking for is a safe way to update the version already installed to be able to use create-react-app, being able to rollback to previous version easily if something doesn't work, I understand that the way is using n.
Thanks in advance.
I suggest you add /usr/local/bin to the start of your PATH (so it comes before /bin).
I do not recommend you try and overwrite /bin/node using n. Something else installed /bin/node in a system directory, and overwriting it using n could leave things in a mixed and confused state. n installs to /usr/local by default, but you can set N_PREFIX to install to your home folder, for example.
To avoid confusion with having two versions of node installed, you may wish to uninstall the /bin version, likely installed by your platform package manager.
Tip: Changing where node and npm are installed is likely to change where your global npm packages are installed. I suggest you list what you have installed now in case you want to reinstall then in the "new" location. npm list -g --depth=0

Cannot find Typescript using NVM

I have nvm installed and recently fixed an issue with a conflict with a previously installed version of node. Fixing it meant removing the node executable from the prior location. Some things still work but I'm getting this error:
Cannot find module 'typescript'
and this fix didn't help me:
How to fix Cannot find module 'typescript' in Angular 4?
running ng new is what is triggering the error.
I have typescript installed globally. And to ensure that is installed with this version of node, I ran:
nvm use 10 && npm i -g typescript
/Users/username/.nvm/versions/node/v10.16.0/lib/node_modules/typescript/bin/tsserver
Thanks,
Wayne
When using nvm, every node version has it's own globally installed dependencies. If you are not finding something you have installed previously for a different version of node (or you have removed it), this can be a reason.
For anyone coming across this question, I found the answer here.
How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
I had to do all of the steps in the most accepted answer. I also had to:
rm -Rf /user/local/bin/node_modules
It might be a good idea to search your machine for all node_modules folders and, of course, ignore any "local" versions. And delete all of them that are not in your nvm directory. That directory will look somehting like:
/Users/username/.nvm/versions/node/v#####/lib/node_modules
You can identify yours using:
npm root -g

Global Node Packages Installed to Wrong Directory

I'm trying to install Hexo globally using npm. When I run
npm install -g hexo-cli
I'm informed that it was installed to /Users/myusername/.node/bin/hexo -> /Users/myusername/.node/lib/node_modules/hexo-cli/bin/hexo
The problem comes in when I run hexo init blog and the hexo command is not found.
I installed Node and npm with Homebrew, so when I run which node and which npm, the results are /usr/local/bin/node and /usr/local/bin/npm respectively.
I'm thinking that I still have leftover files and directories from when I installed Node without homebrew, but I don't want to start deleting things without fully knowing the repercussions. Would I be safe to delete all files located in the /Users/myusername/.node/ directory? I can't figure out why npm is not installing to the proper directory.
After a little digging, I found that my npm prefix variable was pointing do the wrong directory, left behind by the old Node installation. I ran npm config get prefix to see where it was pointing.
I set the new prefix value using npm config set prefix /usr/local. Homebrew is symlinked with this directory via /usr/local/bin. I uninstalled hexo-cli and reinstalled through npm, and now it works perfectly.
For NVM users
Run nvm use --delete-prefix v10.13.0 --silent replacing v10.13.0 with whatever version of node you're using.
A simple way to cope with environment variables/path problems on Windows:
Run command:
npm install -g hexo
Using node.js command prompt rather than cmd windows provided by Windows itself.

npm comes with node now. What does this mean?

Node noob here.
I had previously installed both npm and node separately.
Apparently, npm comes with node now. (link)
To my newbie mind, this means my previous dual installation is old and ugly. 1 binary > 2 binaries. So i uninstalled both.
Then I installed the latest node following the procedure. (i am running eOS)
Terminal
user#box:-$ which node
/usr/bin/node
user#box:-$ node -v
v0.10.22
user#box:-$ which npm
user#box:-$ npm -v
bash: /usr/bin/npm: No such file or directory
I can always run:
curl https://npmjs.org/install.sh | sh
but that seems to indicate that npm is actually NOT included in node.
When they say they are included do they just mean the code is in the same repo, but the binaries are still different?
Final question I have /usr/bin/node as well as /usr/bin/nodejs
can i delete one of these? im not sure when/where i picked up a second copy.
Yes, the nodejs package includes both node and npm executables. The code for each has its own repo, but when packaged both are included.
npm source: https://github.com/isaacs/npm
node source: https://github.com/joyent/node
When you install that .deb file from the PPA, you should get both /usr/bin/nodejs and /usr/bin/npm and 2 symlinks at /usr/bin/node (which points to) /etc/alternatives/node (which points to /usr/bin/nodejs).
If any of this isn't true, your install didn't fully succeed, most likely due to conflicting files you left around from your manual install. I would suggest uninstalling the .deb then making sure there are no stale files left from your manual install and then installing again.
Only node.js packages comes with npm. so if you are installing using an .msi, .exe, .dmg .pkg, .deb or using a package installer like apt-get, yum or brew, then you'll have both node and npm.
However,npm is not part of the node core. if you are installing node and using a method where you are using ./configure or make install || make link, then npm will not be installed, and will need to be compiled using the same type of installation, and node will have to be placed on your path.
If you used git, or unzipped node and you can see a configure script, then you will also need to acquire npm.
I've had issues (mostly on Mac) with npm ending up in directories that aren't in the terminal PATH. If you can figure out where npm is located, you can just add it to your path with something like:
export PATH=$PATH:/path/to/npm
I think (I'm not on a mac so I can't check at the moment) that it sometimes gets put in /usr/local/share/. But at any rate, the problem is likely NOT that npm isn't installed, but that it's installed somewhere you're not expecting.
Few months ago i had started learning the react so all this stuff i needed to install my laptop that had the ubuntu operating system.
What i did -- First i installed the node and without knowing that it came up with the npm package. I installed the npm package again.. but there was no conflict at all.
But after exploring all these things that nodejs have npm package. So i uninstalled the npm package due to concern about memory usage..
And Now everything is working fine....
