Installing Windows nvm using PowerShell

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.

Installing from github.com

Retrieve install script from github.com directly:

cd $Env:USERPROFILE;
Invoke-WebRequest https://raw.githubusercontent.com/jchip/nvm/v1.6.0/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1

Installing from unpkg.com

Retrieve install script from unpkg.com:

cd $Env:USERPROFILE;
Invoke-WebRequest https://unpkg.com/@jchip/nvm@1.6.0/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1

Installing from jsdelivr.net

Retrieve install script from jsdelivr.net:

cd $Env:USERPROFILE;
Invoke-WebRequest https://cdn.jsdelivr.net/npm/@jchip/nvm@1.6.0/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1

Windows 7 Updates

PowerShell version 4+ is required.

For Windows 7, you can update it to version 5.1 with the following instructions:

  1. Go to https://www.microsoft.com/en-us/download/details.aspx?id=54616
  2. Click Red Download button
  3. Download Win7AndW2K8R2-KB3191566-x64.zip or Win7-KB3191566-x86.zip for 32-bit
  4. Unzip the file
  5. Run the package Win7AndW2K8R2-KB3191566-x64.msu or Win7-KB3191566-x86.msu for 32-bit

After it's completed and rebooted, launch PowerShell and type $PSVersionTable to check.

PSVersion should be something like 5.1.#####.####

Troubleshooting

Running scripts disabled

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.

No PowerShell - Manual Install

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:

  1. Download the package zip file from https://github.com/jchip/nvm/archive/v1.5.8.zip
    1. Extract this file to your home directory. You will get a new directory nvm-1.5.8.
    2. Rename it to nvm, for example: C:\Users\<username>\nvm
  2. Download the zipfile https://nodejs.org/dist/v20.12.1/node-v20.12.1-win-x64.zip
    1. Extract this file to C:\Users\<username>\nvm. You will get a new directory node-v20.12.1-win-x64
    2. Move node.exe from that directory into C:\Users\<username>\nvm
    3. (optional) You can delete the directory after if you want.
  3. Open RegEdit.exe, in HKEY_CURRENT_USER/Environment
    1. Add the following entries
      1. NVM_HOME -> C:\Users\<username>\nvm
      2. NVM_LINK -> C:\Users\<username>\nvm\nodejs\bin
    2. Append the following to the entry Path
      1. ;C:\Users\<username>\nvm\bin;C:\users\<username>\nvm\nodejs\bin
  4. Open Command Prompt, and run nvm install lts, note the version installed, and then nvm link <version>.

Make sure to replace <username> above with your actual user name.

Installing Unix nvm

Because this is implemented in node.js, it happens to work on Unix also. It just need a different install script using bash.

Please pick one and then copy and paste it into a bash terminal to run.
