    • Install is simple with a PowerShell script on Windows, or a bash script on Unix.

    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/v1.5.4/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@1.5.4/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@1.5.4/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

    If you absolutely can't have PowerShell, then please submit an issue. I will make a list of manual steps to install this, and if there's interest, then I will make a standalone installer using 7zip.

    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.

    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.

    Installing from github.com

    Retrieve the install script from github.com:

    Using cURL and the install script:

    NVM_HOME=~/nvm curl -o- https://raw.githubusercontent.com/jchip/nvm/v1.5.4/install.sh | bash

    or wget:

    NVM_HOME=~/nvm wget -qO- https://raw.githubusercontent.com/jchip/nvm/v1.5.4/install.sh | bash

    Installing from unpkg.com

    Retrieve the install script from unpkg.com:

    Using cURL and the install script:

    NVM_HOME=~/nvm curl -o- https://unpkg.com/@jchip/nvm@1.5.4/install.sh | bash

    or wget:

    NVM_HOME=~/nvm wget -qO- https://unpkg.com/@jchip/nvm@1.5.4/install.sh | bash

    Installing from jsdelivr.net
