Intro

nvm allows you to quickly install and use different versions of node via the command line.

Example:

$ nvm install 24
Now using node v24.14.0 (npm v11.9.0)
$ node -v
v24.14.0
$ nvm use 22
Now using node v22.22.1 (npm v10.9.4)
$ node -v
v22.22.1
$ nvm use 20
Now using node v20.20.1 (npm v10.8.2)
$ node -v
v20.20.1

Simple as that!

About

nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and Windows WSL.

Installing and Updating

Install & Update Script

To install or update nvm, you should run the [install script][2]. To do that, you may either download and run the script manually, or use the following cURL or Wget command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | bash

Running either of the above commands downloads a script and runs it. The script clones the nvm repository to ~/.nvm, and attempts to add the source lines from the snippet below to the correct profile file (~/.bashrc, ~/.bash_profile, ~/.zshrc, or ~/.profile). If you find the install script is updating the wrong profile file, set the $PROFILE env var to the profile file’s path, and then rerun the installation script.

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

Additional Notes

• If the environment variable $XDG_CONFIG_HOME is present, it will place the nvm files there.

• You can add --no-use to the end of the above script to postpone using nvm until you manually use it:

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" --no-use # This loads nvm, without auto-using the default version

• You can customize the install source, directory, profile, and version using the NVM_SOURCE, NVM_DIR, PROFILE, and NODE_VERSION variables. Eg: curl ... | NVM_DIR="path/to/nvm". Ensure that the NVM_DIR does not contain a trailing slash.

• The installer can use git, curl, or wget to download nvm, whichever is available.

• You can instruct the installer to not edit your shell config (for example if you already get completions via a zsh nvm plugin) by setting PROFILE=/dev/null before running the install.sh script. Here's an example one-line command to do that: PROFILE=/dev/null bash -c 'curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | bash'

Installing in Docker

When invoking bash as a non-interactive shell, like in a Docker container, none of the regular profile files are sourced. In order to use nvm, node, and npm like normal, you can instead specify the special BASH_ENV variable, which bash sources when invoked non-interactively.

# Use bash for the shell
SHELL ["/bin/bash", "-o", "pipefail", "-c"]

# Create a script file sourced by both interactive and non-interactive bash shells
ENV BASH_ENV="${HOME:-/root}/.bash_env"
RUN touch "${BASH_ENV}"
RUN echo '. "${BASH_ENV}"' >> ~/.bashrc

# Download and install nvm
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | PROFILE="${BASH_ENV}" bash
RUN echo node > .nvmrc
RUN nvm install

Installing in Docker for CICD-Jobs

More robust, works in CI/CD-Jobs. Can be run in interactive and non-interactive containers. See https://github.com/nvm-sh/nvm/issues/3531.

FROM ubuntu:latest
ARG NODE_VERSION=20

# install curl
RUN apt update && apt install curl -y

# install nvm
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | bash

# set env
ENV NVM_DIR="${HOME:-/root}/.nvm"

# install node
RUN bash -c "source $NVM_DIR/nvm.sh && nvm install $NODE_VERSION"

# set ENTRYPOINT for reloading nvm-environment
ENTRYPOINT ["bash", "-c", "source $NVM_DIR/nvm.sh && exec \"$@\"", "--"]

# set cmd to bash
CMD ["/bin/bash"]

This example defaults to installation of nodejs version 20.x.y. Optionally you can easily override the version with docker build args like:

docker build -t nvmimage --build-arg NODE_VERSION=19 .

After creation of the image you can start container interactively and run commands, for example:

docker run --rm -it nvmimage

root@0a6b5a237c14:/# nvm -v
0.40.8

root@0a6b5a237c14:/# node -v
v19.9.0

root@0a6b5a237c14:/# npm -v
9.6.3

Noninteractive example:

user@host:/tmp/test $ docker run --rm -it nvmimage node -v
v19.9.0
user@host:/tmp/test $ docker run --rm -it nvmimage npm -v
9.6.3

Troubleshooting on Linux

On Linux, after running the install script, if you get nvm: command not found or see no feedback from your terminal after you type command -v nvm, simply close your current terminal, open a new terminal, and try verifying again. Alternatively, you can run the following commands for the different shells on the command line:

bash: source ~/.bashrc

zsh: source ~/.zshrc

ksh: . ~/.profile

These should pick up the nvm command.

Troubleshooting on macOS

Since OS X 10.9, /usr/bin/git has been preset by Xcode command line tools, which means we can't properly detect if Git is installed or not. You need to manually install the Xcode command line tools before running the install script, otherwise, it'll fail. (see #1782)

If you get nvm: command not found after running the install script, one of the following might be the reason:

• Since macOS 10.15, the default shell is zsh and nvm will look for .zshrc to update, none is installed by default. Create one with touch ~/.zshrc and run the install script again.

• If you use bash, the previous default shell, your system may not have .bash_profile or .bashrc files where the command is set up. Create one of them with touch ~/.bash_profile or touch ~/.bashrc and run the install script again. Then, run . ~/.bash_profile or . ~/.bashrc to pick up the nvm command.

• You have previously used bash, but you have zsh installed. You need to manually add [these lines](#manua
