@jchip/nvm
Advanced tools
A universal node.js version manager for Windows (no admin) and Unix.
Install is simple with a PowerShell script on Windows, or a bash script on Unix.
No admin required on Windows to install or use.
A linked system wide version that can be changed any time.
Change to any version independently in a terminal any time.
You don't need admin rights to install or use, only the permission to execute PowerShell scripts.
Tested on Windows 10, 8.1, and 7. Windows 7 requires PowerShell updates, see update instructions.
To install, start a Windows PowerShell and copy and paste one of the scripts below into the shell terminal and press enter.
This will install nvm and current LTS Node.js (v12.13.0) to directory nvm under your home specified by $Env:USERPROFILE.
If you want to install this under another directory, then set it with the param -nvmhome.
If you don't set it, then $Env:NVM_HOME will be checked, and if non-existent, then a Directory Browser dialog will be opened for you to create and choose a directory.

You can retrieve the install script from multiple sources. Listed below are three options for you to choose from in case one of them is down.
Retrieve install script from github.com directly:
cd $Env:USERPROFILE;
Invoke-WebRequest https://raw.githubusercontent.com/jchip/nvm/v1.6.2/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1
Retrieve install script from unpkg.com:
cd $Env:USERPROFILE;
Invoke-WebRequest https://unpkg.com/@jchip/nvm@1.6.2/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1
Retrieve install script from jsdelivr.net:
cd $Env:USERPROFILE;
Invoke-WebRequest https://cdn.jsdelivr.net/npm/@jchip/nvm@1.6.2/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1
PowerShell version 4+ is required.
For Windows 7, you can update it to version 5.1 with the following instructions:
Win7AndW2K8R2-KB3191566-x64.zip or Win7-KB3191566-x86.zip for 32-bitWin7AndW2K8R2-KB3191566-x64.msu or Win7-KB3191566-x86.msu for 32-bitAfter it's completed and rebooted, launch PowerShell and type $PSVersionTable to check.
PSVersion should be something like
5.1.#####.####

If you get the error:
install.ps1 cannot be loaded because running scripts is disabled on this system.
Then you need to set execution policy for PowerShell to RemoteSigned with the command:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
See this StackOverflow question for details.
You need to keep this policy if you want to use nvm in PowerShell to switch node.js versions.
If for some reason you absolutely can't have PowerShell or permission to install from it, then you can try to manually install following these steps:
nvm-1.6.2.nvm, for example: C:\Users\<username>\nvmC:\Users\<username>\nvm. You will get a new directory node-v20.12.1-win-x64node.exe from that directory into C:\Users\<username>\nvmRegEdit.exe, in HKEY_CURRENT_USER/Environment
NVM_HOME -> C:\Users\<username>\nvmNVM_LINK -> C:\Users\<username>\nvm\nodejs\binPath
;C:\Users\<username>\nvm\bin;C:\users\<username>\nvm\nodejs\binnvm install lts, note the version installed, and then nvm link <version>.Make sure to replace <username> above with your actual user name.
Because this is implemented in node.js, it happens to work on Unix also. It just need a different install script using bash.
To retrieve and run the install script, provided below are three options for you to choose from in case one of them is down.
Please pick one and then copy and paste it into a bash terminal to run.
Retrieve the install script from github.com:
Using cURL and the install script:
NVM_HOME=~/nvm curl -o- https://raw.githubusercontent.com/jchip/nvm/v1.6.2/install.sh | bash
or wget:
NVM_HOME=~/nvm wget -qO- https://raw.githubusercontent.com/jchip/nvm/v1.6.2/install.sh | bash
Retrieve the install script from unpkg.com:
Using cURL and the install script:
NVM_HOME=~/nvm curl -o- https://unpkg.com/@jchip/nvm@1.6.2/install.sh | bash
