export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"
```
</Step>

<Step title="Determine if the bun binary is properly installed">
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
& "$env:USERPROFILE\.bun\bin\bun" --version
```
If the command runs successfully but `bun --version` is not recognized, it means that bun is not in your system's PATH. To fix this, open a Powershell terminal and run the following command:
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
[System.Environment]::SetEnvironmentVariable(
"Path",
[System.Environment]::GetEnvironmentVariable("Path", "User") + ";$env:USERPROFILE\.bun\bin",
[System.EnvironmentVariableTarget]::User
)
```
</Step>
<Step title="Restart your terminal">
After running the command, restart your terminal and test with `bun --version`
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun --version
```
</Step>

Upgrading
Once installed, the binary can upgrade itself:
bun upgrade
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:
# 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
Since Bun is a single binary, you can install older versions by re-running the installer script with a specific version.
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
curl -fsSL https://bun.com/install | bash -s "bun-v1.3.3"
```
```powershell PowerShell icon="windows" theme={"theme":{"light":"github-light","dark":"dracula"}}
iex "& {$(irm https://bun.com/install.ps1)} -Version 1.3.3"
```
