Checking installation

To check that Bun was installed successfully, open a new terminal window and run bun --version.

bun --version
1.x.y

To see the precise commit of oven-sh/bun that you're using, run bun --revision.

bun --revision
1.x.y+b7982ac13189

If you've installed Bun but are seeing a command not found error, you may have to manually add the installation directory (~/.bun/bin) to your PATH.

How to add to your PATH

First, determine what shell you're using:

echo $SHELL
/bin/zsh # or /bin/bash or /bin/fish

Then add these lines below to bottom of your shell's configuration file.

~/.zshrc

~/.bashrc

~/.config/fish/config.fish

~/.zshrc
# add to ~/.zshrc
export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"

~/.bashrc
# add to ~/.bashrc
export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"

~/.config/fish/config.fish
# add to ~/.config/fish/config.fish
export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"

Save the file. You'll need to open a new shell/terminal window for the changes to take effect.

Upgrading

Once installed, the binary can upgrade itself.

bun upgrade

Homebrew users — To avoid conflicts with Homebrew, use brew upgrade bun instead.

Scoop users — To avoid conflicts with Scoop, use scoop update bun instead.

Canary builds

Bun automatically releases an (untested) canary build on every commit to main. To upgrade to the latest canary build:

bun upgrade --canary

The canary build is useful for testing new features and bug fixes before they're released in a stable build. To help the Bun team fix bugs faster, canary builds automatically upload crash reports to Bun's team.

View canary build

Note — To switch back to a stable release from canary, run bun upgrade --stable.

Installing older versions of Bun

Since Bun is a single binary, you can install older versions of Bun by re-running the installer script with a specific version.

Installing a specific version of Bun on Linux/Mac

To install a specific version of Bun, you can pass the git tag of the version you want to install to the install script, such as bun-v1.1.6 or bun-v1.1.1.

curl -fsSL https://bun.sh/install | bash -s "bun-v1.1.6"

Installing a specific version of Bun on Windows

On Windows, you can install a specific version of Bun by passing the version number to the Powershell install script.

# PowerShell:
iex "& {$(irm https://bun.sh/install.ps1)} -Version 1.1.6"

Downloading Bun binaries directly

To download Bun binaries directly, you can visit the releases page page on GitHub.

For convenience, here are download links for the latest version:

The musl binaries are built for distributions that do not ship with the glibc libraries by default, instead relying on musl. The two most popular distros are Void Linux and Alpine Linux, with the latter is used heavily in Docker containers. If you encounter an error like the following: bun: /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.29' not found (required by bun), try using the musl binary. Bun's install script automatically chooses the correct binary for your system.

The baseline binaries are built for older CPUs which may not support AVX2 instructions. If you run into an "Illegal Instruction" error when running Bun, try using the baseline binaries instead. Bun's install scripts automatically chooses the correct binary for your system which helps avoid this issue. Baseline builds are slower than regular builds, so use them only if necessary.

Uninstall

If you need to remove Bun from your system, use the following commands.
