Add the Bun directory to PATH

Add this line to your configuration file:
terminal
export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"

Canary Builds

-> View canary build Bun automatically releases an (untested) canary build on every commit to main. To upgrade to the latest canary build:
terminal
# Upgrade to latest canary
bun upgrade --canary

# Switch back to stable
bun upgrade --stable
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.

​
Installing Older Versions

Musl Binaries

For distributions without glibc (Alpine Linux, Void Linux):
If you encounter an error like bun: /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.29 not found, try using the musl binary. Bun’s install script automatically chooses the correct binary for your system.

​
CPU Requirements

Bun has specific CPU requirements based on the binary you’re using:
  • Standard Builds
  • Baseline Builds
x64 binaries target the Haswell CPU architecture (AVX and AVX2 instructions required) | Platform | Intel Requirement | AMD Requirement | |----------|------------------|-----------------| | x64 | Haswell (4th gen Core) or newer | Excavator or newer |
Bun does not support CPUs older than the baseline target, which mandates the SSE4.2 extension. macOS requires version 13.0 or later.

​
Uninstall

To remove Bun from your system:
  • macOS & Linux
  • Windows
  • Package Managers
bash terminal icon="terminal" rm -rf ~/.bun
