52 If you see `The token '&&' is not a valid statement separator`, you're in PowerShell, not CMD. If you see `'irm' is not recognized as an internal or external command`, you're in CMD, not PowerShell. Your prompt shows `PS C:\` when you're in PowerShell and `C:\` without the `PS` when you're in CMD.52 如果您看到 `The token '&&' is not a valid statement separator`，表示您在 PowerShell 中，而非 CMD。如果您看到 `'irm' is not recognized as an internal or external command`，表示您在 CMD 中，而非 PowerShell。當您在 PowerShell 中時，提示符會顯示 `PS C:\`，而在 CMD 中時會顯示 `C:\`（不含 `PS`）。

54 If the install command fails with `syntax error near unexpected token '<'`, a `403`, or another curl error, see [Troubleshoot installation](/docs/en/troubleshoot-install#find-your-error) to match the error to a fix and for alternative install methods.54 如果安裝命令失敗並出現 `syntax error near unexpected token '<'`、`403` 或其他 curl 錯誤，請參閱[疑難排解安裝](/docs/zh-TW/troubleshoot-install#find-your-error)以將錯誤與修正相對應，並查看替代安裝方法。

56 [Git for Windows](https://git-scm.com/downloads/win) is recommended on native Windows so Claude Code can use the Bash tool. If Git for Windows is not installed, Claude Code uses PowerShell as the shell tool instead. WSL setups do not need Git for Windows.56 建議在原生 Windows 上安裝 [Git for Windows](https://git-scm.com/downloads/win)，以便 Claude Code 可以使用 Bash 工具。如果未安裝 Git for Windows，Claude Code 會改用 PowerShell 作為殼層工具。WSL 設定不需要 Git for Windows。
