fnm
)🚀 Fast and simple Node.js version manager, built in Rust
🌎 Cross-platform support (macOS, Windows, Linux)
✨ Single file, easy installation, instant startup
🚀 Built with speed in mind
🤔 Works with .node-version
and .nvmrc
files
For bash
, zsh
and fish
shells, there’s an automatic installation script:
curl -fsSL https://fnm.vercel.app/install | bash
On macOS, it is as simple as brew upgrade fnm
.
On other operating systems, upgrading fnm
is almost the same as installing it. To prevent duplication in your shell config file add --skip-shell
to install command.
--install-dir
Set a custom directory for fnm to be installed. The default is $HOME/.fnm
.
--skip-shell
Skip appending shell specific loader to shell config file, based on the current user shell, defined in $SHELL
. e.g. for Bash, $HOME/.bashrc
. $HOME/.zshrc
for Zsh. For Fish - $HOME/.config/fish/conf.d/fnm.fish
--force-install
macOS installations using the installation script are deprecated in favor of the Homebrew formula, but this forces the script to install using it anyway.
Example:
curl -fsSL https://fnm.vercel.app/install | bash -s -- --install-dir "./.fnm" --skip-shell
brew install fnm
Then, set up your shell for fnm
scoop install fnm
Then, set up your shell for fnm
cargo install fnm
Then, set up your shell for fnm
PATH
environment variableTo remove fnm ( 😢), just delete the .fnm
folder in your home directory. You should also edit your shell configuration to remove any references to fnm (ie. read Shell Setup, and do the opposite).
fnm ships its completions with the binary:
fnm completions --shell <SHELL>
Where <SHELL>
can be one of the supported shells:
bash
zsh
fish
powershell
Please follow your shell instructions to install them.
fnm needs to run some shell commands before you can start using it. This is done by evaluating the output of fnm env
. Check out the following guides for the shell you use:
add the following to your .bashrc
profile:
eval "$(fnm env)"
add the following to your .zshrc
profile:
eval "$(fnm env)"
create ~/.config/fish/conf.d/fnm.fish
add this line to it:
fnm env | source
Before adding any configuration to your shell, you’d need to enable symlink support for a standard accounts (non-administrator).
You can do it by enabling Developer Mode, or updating the Local Security Policy.
Open Local Security Policy
(secpol.msc
) and go to Local Policies
-> User Rights Assignment
, select Create symbolic links
, add your user to the list and reboot.
Use
whoami
if you are not sure what’s your user name.
Add the following to the end of your profile file:
fnm env --use-on-cd | Out-String | Invoke-Expression
~\Documents\PowerShell\Microsoft.PowerShell_profile.ps1
or $PROFILE
~/.config/powershell/Microsoft.PowerShell_profile.ps1
fnm is also supported but is not entirely covered. You can set up a startup script and append the following line:
FOR /f "tokens=*" %i IN ('fnm env --use-on-cd') DO CALL %i
⚠️ If you get the error i was unexpected at this time
, please make a .cmd file as suggested by the first step in the Usage with Cmder secton add it’s path to the AutoRun
registry key.
Usage is very similar to the normal WinCMD install, apart for a few tweaks to allow being called from the cmder startup script. The example assumes that the CMDER_ROOT
environment variable is set to the root directory of your Cmder installation.
Then you can do something like this:
:: %CMDER_ROOT%\bin\fnm_init.cmd
@echo off
FOR /f "tokens=*" %%z IN ('fnm env --use-on-cd') DO CALL %%z
:: %CMDER_ROOT%\config\user_profile.cmd
call "%CMDER_ROOT%\bin\fnm_init.cmd"
You can replace %CMDER_ROOT%
with any other convenient path too.
