I recently decided to install nvm, and the instructions had me uninstall node. I noticed that if I explicitly tell nvm to use a certain version it uses it from the nvm directory, otherwise it uses my bin/node directory, so I didn't notice a conflict. When I uninstalled node, i needed to specify a version every time I use my terminal which seems like an unnecessary step when I could just leave node installed via brew and use nvm if I need to version control.
Once you install nvm and use Node through it, it does NOT use bin/node, but the version installed with nvm, so your old Node is obsolete.
The main reason they recommend you to uninstall Node is because it could confuse the shell about which Node to use. Of course, you can update your shell config so that it first looks for Node installed from nvm, but that's an unnecessary extra step and your old Node distribution is obsolete on your disk, at best.
So, the best solution is uninstalling the old distribution and install nvm (which by default installs the latest Node in your .nvm folder), and install more versions of Node if necessary.
And regarding this:
i needed to specify a version every time I use my terminal which seems like an unnecessary step
You don't need to, as long as you set the default version (say, 11.15.0) config after installing nvm with the following command:
nvm alias default 11.15.0
I am trying to update my local node version from 8.9.0 to 8.10.0 using nvm. But it's not getting reflected. Here's what I tried:
node -v
-> v8.9.0
nvm use 8.10.0
-> Now using node v8.10.0 (npm v5.5.1)
node -v
-> v8.9.0
I am unable to get why it won't change. Please let me know what have I done wrong.
Adding few notes about my experience on debugging this problem.
First, I started out with the command provided by Jonathan which -a node and got the same output as op:
/usr/local/bin/node
/Users/<my-user>/.nvm/versions/node/v8.10.0/bin/node
Moving on to the next comment by Jonathan: Have you installed Node via Homebrew as well?, I tried uninstalling node by brew uninstall node and got and error that said it could not uninstall node as there was another program dependent on it. yarn.
And then realised that brew had installed its own version of node because I installed yarn through brew, which was overwriting the node version that I wanted to use through nvm.
Uninstalling brew's version of yarn+node fixed my problem.
I still needed yarn, and now I have to install yarn globally for each node version managed by nvm.
Inconvenient, I agree. But so is maintaining twenty thousand versions of node for each project so not very different in my opinion.
All of this was done on M1 MacOS and your output might vary based on your system.
Please ensure that when you input arch on command prompt, then output is i386.
This is achieved using Rosetta.
Following sequence of commands on terminal worked: -
nvm install 8.10.0
nvm install --lts
nvm ls
brew upgrade
arch -arm64 brew install n
n
Now select node version 8.10.0 using up or down arrow keys in keyboard and then quit from command prompt using command+q
Please do not try brew uninstall --ignore-dependencies node
Just check you environment variables first. It might be mapping to node#8.9.0.
You need to remove the environment variable first.
If you are also using volta. Volta may take precedence.
Use which -a node to verify.
If that is the case, use volta pin node#version to switch.
First check your nvm version installed on your local system. go to command prompt and type "nvm list" If you don't see the versions 8.10.0 in the list then install using command : "nvm install 8.10.0" and then try "nvm use 8.10.0".

I want to upgrade npm but I need Node version >0.10.32
Typing $ brew upgrade node I get:
Error: node 7.2.1 already installed
but with $ node -v I get:
v0.10.24
Why are there two version formats and how can I get node updated to the required version?
I need
You have two different versions of Node installed in different paths.
The one in the directory closer to the front of your $PATH environment variable is 0.10.24.
The one installed by brew is 7.2.1.
If you want to use the brew managed one, then the easiest thing to do is to uninstall the other version.
Alternatively, use the full path to the brew managed one.
Have installed node 0.12.2, but need to revert to 0.10.33 to run the applications I need to.
I have tried installing 0.10.33 and switching versions using
set 0.10.33 to default with 'nvm alias default 0.10.33'
But node runs previous version (0.12.2) when started again.
I have tried uninstalling node via various methods, but each one has been blocked:
uninstall node
"You must be in root to run this tool"
(I am the only user (with Admin access) on my machine
I tried
cd /
then
uninstall node
But still got
"You must be in root to run this tool"
Tried
sudo uninstall node
"Uninstall Failed...
Reason: ErrorMissingBundle"
I may have installed node with Homebrew - it was a while back, can't quite remember. So tried:
brew uninstall node
"Error: No such keg: /usr/local/Cellar/node"
Other information I can give:
which node
/usr/local/bin/node
I see node and npm in
/usr/local/bin
Any help most appreciated - I'm not a command line expert, and fairly new at Node.
To switch from different node.js version with nvm just use nvm use 0.10.33
It looks like you might be using NVM (node version manager). If you are you can install different versions using
nvm install version_no
and then you can switch versions using the command
nvm use version_no
If you have not used NVM to install node you can uninstall node using the instructions in this answer - How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X).
Then if you need different versions of node I would recommend using NVM, which allows you to install and use different versions of node on the same system. https://github.com/creationix/nvm
I am running Node.js version v0.5.9-pre on Ubuntu 10.10.
I would like to be using version v0.5.0-pre.
How do I roll back to the older version of node?
*NIX (Linux, OS X, ...)
Use n, an extremely simple Node version manager that can be installed via npm.
Say you want Node.js v0.10.x to build Atom.
npm install -g n # Install n globally
n 0.10.33 # Install and use v0.10.33
Usage:
n # Output versions installed
n latest # Install or activate the latest node release
n stable # Install or activate the latest stable node release
n <version> # Install node <version>
n use <version> [args ...] # Execute node <version> with [args ...]
n bin <version> # Output bin path for <version>
n rm <version ...> # Remove the given version(s)
n --latest # Output the latest node version available
n --stable # Output the latest stable node version available
n ls # Output the versions of node available
Windows
Use nvm-windows, it's like nvm but for Windows. Download and run the installer, then:
nvm install v0.10.33 # Install v0.10.33
nvm use v0.10.33 # Use v0.10.33
Usage:
nvm install [version] # Download and install [version]
nvm uninstall [version] # Uninstall [version]
nvm use [version] # Switch to use [version]
nvm list # List installed versions
One way is to use NVM, the Node Version Manager.
Use following command to get nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
You can find it at https://github.com/creationix/nvm
It allows you to easily install and manage multiple versions of node. Here's a snippet from the help:
Usage:
nvm install <version> Download and install a <version>
nvm use <version> Modify PATH to use <version>
nvm ls List versions (installed versions are blue)
Update: Updated the answer because previous one was not relevant.
Follow below steps to update your node version.
1. Install nvm For this run below command in your terminal
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
Note: If above command did not work for you, you can choose another option to install it. I have added an answer for this here
2. Install specific node version using nvm
For this run
Replace 12.14.1 with your node version
nvm install 12.14.1
Note: If you are getting error of NVM not recognised then run below command and then run above again
source ~/.nvm/nvm.sh
3. Make the installed version default
Note: Replace 12.14.1 with your installed version.
nvm alias default 12.14.1
and
nvm use 12.14.1
4. Check node version
node -v
And that's it.
Extra
To check list of installed node versions -- run below command
nvm ls
Why use any extension when you can do this without extension :)
Install specific version of node
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
Specific version : sudo n 4.4.4 instead of sudo n stable
With package.json - The Maintainable and Portable Way 🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉
Lets each project specify its own version
You can add node as a dependency in package.json and control which version is used for a particular project. Upon executing a package.json "script", npm (and yarn) will use that version to run the script instead of the globally installed Node.js.
The node package accomplishes this by downloading a node binary for your local system and puts it into the node_modules/.bin directory.
You can also do this with the npm (or yarn) packages but you'll need to set your PATH up specifically or use something like npx that handles it for you.
Ubuntu - The Official Way (manually) 😵
If you're on node 12 and want to downgrade to node 10, just remove node and follow the instructions for the desired version:
# Remove the version that is currently installed
sudo apt remove -y nodejs
# Setup sources for the version you want
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
# (Re-)Install Node
sudo apt-get install -y nodejs
Windows - The Official Way (manually) 😵
I found myself wanting to downgrade to LTS on Windows from the bleeding edge. If you're not using a package manager like Chocolatey or a node version manager like nvm or n, just download the .msi for the version you want and install it. You might want to remove the currently installed version via "Add or remove programs" tool in Windows.
Windows Package Manager - winget 🎉🎉
The Open Source Windows Package Manager Way
winget install -e --id OpenJS.Nodejs -v 14.9.0
Chocolatey - The Independent Package Manager Way 🎉
Chocolatey is good for keeping installations up to date easily and it is a common way to install Node.js on Windows. I had to remove the bleeding edge version before installing the LTS version:
choco uninstall nodejs
choco install nodejs-lts
Node Version Manager - The "Screw it, I'll do it myself!" Way 😢😢😢ðŸ˜ðŸ˜ðŸ˜ðŸ˜ðŸ˜
While not very portable or easily maintainable, some developers like manually switching which global version of node is active at any given point in time and think the official ways of doing this are too slow. There are two popular Npm packages that provide helpful CLI interfaces for selecting (and automatically installing) whichever version you want for your system: nvm and n. Using either is beyond the scope of this answer.
I highly recommend staying away from this option. Even though it's popular, it's an anti-pattern that is sure to cause headaches in the future. Sure, .nvmrc exists, but this is reinventing something that's already a part of Npm. Just npm i node the version you want.
Windows
Downgrade Node with Chocolately
Install Chocolatey. Then run:
choco install nodejs.install -version 6.3.0
Chocolatey has lots of Node versions available.
Downgrade NPM
npm install -g npm#3.10.3
the easiest way i have found is to just use the nodejs.org site:
go to https://nodejs.org/en/download/releases/
find version you want and click download
on mac click the .pkg executable and follow the installation instructions (not sure what the correct executable is for windows)
be happy now that you are on the version of node you wanted
nvmw is no longer maintained, but I found another source that seems to be up to date (as of 1/4/17).
nvm-windows
It works. Allowed me to downgrade to 6.3.1
You need to install NVM for this.
For Mac
Edit .bash_profile using the below command.
nano .bash_profile
And add the following lines to .bash_profile
export NVM_DIR=~/.nvm
source ~/.nvm/nvm.sh
Save it. Exit the terminal and check the magic.
Then install the required version using the below command.
nvm install v14.18.0
If you want to check the installed node versions on your system. Use the below command.
nvm ls
If you want to use the specific version from the installed node versions. Use below command
nvm use 12.14.4
Another good library for managing multiple versions of Node is N: https://github.com/visionmedia/n
On windows 7 I used the general 'Uninstall Node.js' (just started typing in the search bottom left ,main menu field) followed by clicking the link to the older version which complies with the project, for instance:
Windows 64-bit Installer: https://nodejs.org/dist/v4.4.6/node-v4.4.6-x64.msi
I had node version 6.4.0 .
As i am need of the older version 6.3.0 , i just installed the 6.3.0 version again in my system. node version downgraded automatically.
So, to downgrade the node version ,
Just install the older version of node js . It will get downgraded automatically from the higher version.
I tried in osx . It works like a charm .
Now the v0.5.0-pre has reached end of life. We can use npx to use any stable older version of node. E.g. the earliest stable version is 4.9.0.
npx -p node#4.9.0 -- node -v
run this:
rm -rf node_modules && npm cache clear && npm install
Node will install from whatever is cached. So if you clear everything out first, then NPM use 0.10.xx, it will revert properly.
Easiest way i found -
Uninstall current version
Download the appropriate .msi installer (x64 or x86) for the desired version from https://nodejs.org/download/release/
Use following commnad with your version number
nvm install v8.9
nvm alias default v8.9
nvm use v8.9
For some reason Brew installs node 5 into a separate directory called node5.
The steps I took to get back to version 5 were: (You will need to look up standard brew installation/uninstallation, but otherwise this process is more straightforward than it looks.)
Install node5 using Brew standard installation, BUT don't brew link, yet.
Uninstall all other versions of node using brew unlink node and brew uninstall node. You might need to use --force to remove one of the versions.
Find the cellar folder on your computer
Delete the node folder in the cellar.
Rename the node5 folder to node.
Then, brew link node
You should be all set with node 5.
If you are like, you already install node version you want but can't seem to switch to it, try this:
nvm use --delete-prefix <version>. npm shows the lates version installed but can't switch to it. If so, this is the output you will see:
You need to run "nvm install v16.2.0
Then run:nvm install <type the version you wish to use here>Your output should look like this:
Downloading and installing node v16.2.0... Downloading https://nodejs.org/dist/v16.2.0/node-v16.2.0-linux-x64.tar.xz... ####################################################################### 100.0% Computing checksum with sha256sum Checksums matched! Now using node v16.2.0 (npm v7.13.0) Creating default alias: default -> v16.2.0
You are done! You can see the latest version by running:
node -v
if you want to go to the LTS version of node which is the stable one from the latest/current version simply run this in your directory.
npm i node
this will install the LTS version of node in your directory.
I faced a lot of issue with this and the only solution that worked for me is :
source ~/.nvm/nvm.sh
nvm isntall node_version_you_want
nvm use node_version_you_want
nvm install 0.5.0 #install previous version of choice
nvm alias default 0.5.0 #set it to default
nvm use default #use the new default as active version globally.
Without the last, the active version doesn't change to the new default. So, when you open a new terminal or restart server, the old default version remains active.
follow the steps if u already install curl its work for me
sudo snap remove curl
sudo apt install curl
nvm install 12.2.0
As i can see this was asked a long time ago, but maybe it can be helpful for someone else.
I can recommend this utility (NVS - Node Version Switcher) to someone who is searching for a way to switching between different versions of NodeJS:

The Easiest way I find to install node.js with a specific version:
First uninstall your node.js
Go to, https://nodejs.org/en/download/releases/ and find your desired version.
Select your version and click on the download button.
Download .msi file
