## Installation¶
¶
To install Claude Code, use one of the following methods:¶
¶
<Tabs>¶
<Tab title="Native Install (Recommended)">¶
**macOS, Linux, WSL:**¶
¶
```bash theme={null}¶
curl -fsSL https://claude.ai/install.sh | bash¶
```¶
¶
**Windows PowerShell:**¶
¶
```powershell theme={null}¶
irm https://claude.ai/install.ps1 | iex¶
```¶
¶

¶
```batch theme={null}¶
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd¶
```¶
¶
<Info>¶
Native installations automatically update in the background to keep you on the latest version.¶
</Info>¶
</Tab>¶
¶
<Tab title="Homebrew">¶
```sh theme={null}¶
brew install --cask claude-code¶
```¶
¶
<Info>¶
Homebrew installations do not auto-update. Run `brew upgrade claude-code` periodically to get the latest features and security fixes.¶
</Info>¶
</Tab>¶
¶
<Tab title="WinGet">¶
```powershell theme={null}¶
winget install Anthropic.ClaudeCode¶
```¶
¶
<Info>¶
WinGet installations do not auto-update. Run `winget upgrade Anthropic.ClaudeCode` periodically to get the latest features and security fixes.¶
</Info>¶
</Tab>¶
</Tabs>¶
¶
After the installation process completes, navigate to your project and start Claude Code:¶
¶
```bash theme={null}¶
cd your-awesome-project¶
claude¶
```¶
¶
If you encounter any issues during installation, consult the [troubleshooting guide](/en/troubleshooting).¶
¶
<Tip>¶
Run `claude doctor` after installation to check your installation type and version.¶
</Tip>¶
¶
<Note>¶
**Alpine Linux and other musl/uClibc-based distributions**: The native installer requires `libgcc`, `libstdc++`, and `ripgrep`. For Alpine: `apk add libgcc libstdc++ ripgrep`. Set `USE_BUILTIN_RIPGREP=0`.¶
</Note>¶
¶
### Authentication¶
¶
#### For individuals¶
¶
1. **Claude Pro or Max plan** (recommended): Subscribe to Claude's [Pro or Max plan](https://claude.ai/pricing) for a unified subscription that includes both Claude Code and Claude on the web. Manage your account in one place and log in with your Claude.ai account.¶
2. **Claude Console**: Connect through the [Claude Console](https://console.anthropic.com) and complete the OAuth process. Requires active billing in the Anthropic Console. A "Claude Code" workspace is automatically created for usage tracking and cost management. You can't create API keys for the Claude Code workspace; it's dedicated exclusively for Claude Code usage.¶

¶
1. **Claude for Teams or Enterprise** (recommended): Subscribe to [Claude for Teams](https://claude.com/pricing#team-&-enterprise) or [Claude for Enterprise](https://anthropic.com/contact-sales) for centralized billing, team management, and access to both Claude Code and Claude on the web. Team members log in with their Claude.ai accounts.¶
2. **Claude Console with team billing**: Set up a shared [Claude Console](https://console.anthropic.com) organization with team billing. Invite team members and assign roles for usage tracking.¶
3. **Cloud providers**: Configure Claude Code to use [Amazon Bedrock, Google Vertex AI, or Microsoft Foundry](/en/third-party-integrations) for deployments with your existing cloud infrastructure.¶
¶
### Install a specific version¶
¶
The native installer accepts either a specific version number or a release channel (`latest` or `stable`). The channel you choose at install time becomes your default for auto-updates. See [Configure release channel](#configure-release-channel) for more information.¶
¶

### 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 (deprecated)¶
¶
NPM installation is deprecated. Use the [native installation](#installation) method when possible. To migrate an existing npm installation to native, run `claude install`.¶
¶
**Global npm installation**¶
¶
```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 [troubleshooting permission errors](/en/troubleshooting#command-not-found-claude-or-permission-errors) for recommended solutions.¶
</Warning>¶
¶
## Windows setup¶
¶
**Option 1: Claude Code within WSL**¶
¶
* Both WSL 1 and WSL 2 are supported¶
* WSL 2 supports [sandboxing](/en/sandboxing) for enhanced security. WSL 1 does not support sandboxing.¶
¶
**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"¶
```¶
¶
## Update Claude Code¶
¶
### Auto updates¶
¶
Claude Code automatically keeps itself up to date to ensure you have the latest features and security fixes.¶
¶
* **Update checks**: Performed on startup and periodically while running¶
* **Update process**: Downloads and installs automatically in the background¶
* **Notifications**: You'll see a notification when updates are installed¶
* **Applying updates**: Updates take effect the next time you start Claude Code¶
¶
<Note>¶
Homebrew and WinGet installations do not auto-update. Use `brew upgrade claude-code` or `winget upgrade Anthropic.ClaudeCode` to update manually.¶
¶
**Known issue:** Claude Code may notify you of updates before the new version is available in these package managers. If an upgrade fails, wait and try again later.¶
</Note>¶
¶
### Configure release channel¶
¶
Configure which release channel Claude Code follows for both auto-updates and `claude update` with the `autoUpdatesChannel` setting:¶
¶
* `"latest"` (default): Receive new features as soon as they're released¶
* `"stable"`: Use a version that is typically about one week old, skipping releases with major regressions¶
¶
Configure this via `/config` → **Auto-update channel**, or add it to your [settings.json file](/en/settings):¶
¶
```json theme={null}¶
{¶
"autoUpdatesChannel": "stable"¶
}¶
```¶
¶
For enterprise deployments, you can enforce a consistent release channel across your organization using [managed settings](/en/iampermissions#managed-settings).¶
¶
### Disable auto-updates¶
¶
Set the `DISABLE_AUTOUPDATER` environment variable in your shell or [settings.json file](/en/settings):¶
¶
```bash theme={null}¶
export DISABLE_AUTOUPDATER=1¶
```¶
¶
### Update manually¶
¶
```bash theme={null}¶
claude update¶
```¶
¶
