cd your-awesome-project¶
claude¶
```¶
¶

¶
* Both WSL 1 and WSL 2 are supported¶
¶
**Option 2: Claude Code on native Windows with Git Bash**¶
¶
* Requires [Git for Windows](https://git-scm.com/downloads/win)¶
* For portable Git installations, specify the path to your `bash.exe`:¶
```powershell theme={null}¶
$env:CLAUDE_CODE_GIT_BASH_PATH="C:\Program Files\Git\bin\bash.exe"¶
```¶
¶
## Alternative installation methods¶
¶
Claude Code offers multiple installation methods to suit different environments.¶
¶
If you encounter any issues during installation, consult the [troubleshooting guide](/en/troubleshooting#linux-permission-issues).¶
¶
<Tip>¶
Run `claude doctor` after installation to check your installation type and version.¶
</Tip>¶
¶
### Native installation options¶
¶
The native installation is the recommended method and offers several benefits:¶
¶
* One self-contained executable¶
* No Node.js dependency¶
* Improved auto-updater stability¶
¶
If you have an existing installation of Claude Code, use `claude install` to migrate to the native binary installation.¶
¶
For advanced installation options with the native installer:¶
¶
**macOS, Linux, WSL:**¶
¶
```bash theme={null}¶
# Install stable version (default)¶
curl -fsSL https://claude.ai/install.sh | bash¶
¶
# Install latest version¶
curl -fsSL https://claude.ai/install.sh | bash -s latest¶
¶
# Install specific version number¶
curl -fsSL https://claude.ai/install.sh | bash -s 1.0.58¶
```¶
¶
<Note>¶
**Alpine Linux and other musl/uClibc-based distributions**: The native build requires `libgcc`, `libstdc++`, and `ripgrep`. For Alpine: `apk add libgcc libstdc++ ripgrep`. Set `USE_BUILTIN_RIPGREP=0`.¶
</Note>¶
¶
**Windows PowerShell:**¶
¶
```powershell theme={null}¶
# Install stable version (default)¶
irm https://claude.ai/install.ps1 | iex¶
¶
# Install latest version¶
& ([scriptblock]::Create((irm https://claude.ai/install.ps1))) latest¶
¶
# Install specific version number¶
& ([scriptblock]::Create((irm https://claude.ai/install.ps1))) 1.0.58¶
```¶
¶
**Windows CMD:**¶
¶
```batch theme={null}¶
REM Install stable version (default)¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd¶
¶
REM Install latest version¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd latest && del install.cmd¶
¶
REM Install specific version number¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd 1.0.58 && del install.cmd¶
```¶
¶
<Tip>¶
Make sure that you remove any outdated aliases or symlinks before installing.¶
</Tip>¶
¶
**Binary integrity and code signing**¶
¶
* SHA256 checksums for all platforms are published in the release manifests, currently located at `https://storage.googleapis.com/claude-code-dist-86c565f3-f756-42ad-8dfa-d59b1c096819/claude-code-releases/{VERSION}/manifest.json` (example: replace `{VERSION}` with `2.0.30`)¶
* Signed binaries are distributed for the following platforms:¶
* macOS: Signed by "Anthropic PBC" and notarized by Apple¶
* Windows: Signed by "Anthropic, PBC"¶
¶
### NPM installation¶
¶
For environments where NPM is preferred or required:¶
¶
```sh theme={null}¶
npm install -g @anthropic-ai/claude-code¶
```¶
¶
<Warning>¶
Do NOT use `sudo npm install -g` as this can lead to permission issues and security risks.¶
If you encounter permission errors, see [configure Claude Code](/en/troubleshooting#linux-permission-issues) for recommended solutions.¶
