在 macOS 上安装 PowerShellInstalling PowerShell on macOS
PowerShell 支持 macOS 10.12 及更高版本。PowerShell supports macOS 10.12 and higher. PowerShell 7.0.3 及更高版本和 PowerShell 预览版 7.1.0 及更高版本需要 macOS 10.13 及更高版本。PowerShell 7.0.3 or higher and PowerShell Preview 7.1.0 or higher require macOS 10.13 and higher. GitHub 版本页面上提供有所有可用包。All packages are available on our GitHub releases page. 安装包以后，从终端运行 pwsh。After the package is installed, run pwsh from a terminal.
备注
PowerShell 7 是就地升级，升级后会删除 PowerShell Core 6.x。PowerShell 7 is an in-place upgrade that removes PowerShell Core 6.x.
/usr/local/microsoft/powershell/6 文件夹被替换为 /usr/local/microsoft/powershell/7。The /usr/local/microsoft/powershell/6 folder is replaced by /usr/local/microsoft/powershell/7.
如果需要与 PowerShell 7 并行运行 PowerShell 6，请使用二进制存档方法重新安装 PowerShell 6。If you need to run PowerShell 6 side-by-side with PowerShell 7, reinstall PowerShell 6 using the binary archive method.
可采用多种方法在 macOS 上安装 PowerShell。There are several ways to install PowerShell on macOS. 选择下列方法之一：Choose one of the following methods:
- 使用 Homebrew 安装。Install using Homebrew. Homebrew 是 macOS 的首选包管理器。Homebrew is the preferred package manager for macOS.
- 通过直接下载安装 PowerShellInstall PowerShell via Direct Download
- 从二进制存档安装Install from binary archives.
安装 PowerShell 后，应安装 OpenSSL。After installing PowerShell, you should install OpenSSL. PowerShell 远程处理和 CIM 操作均需要 OpenSSL。OpenSSL is needed for PowerShell remoting and CIM operations.
通过 Homebrew 在 macOS 10.13 或更高版本上安装最新的稳定版本Installation of latest stable release via Homebrew on macOS 10.13 or higher
如果未找到 brew 命令，则需要按照说明安装 Homebrew。If the brew command is not found, you need to install Homebrew following their instructions.
现在，可以开始安装 PowerShell：Now, you can install PowerShell:
brew cask install powershell
最后，验证安装是否正常运行：Finally, verify that your install is working properly:
pwsh
PowerShell 新版本发布后，更新 Homebrew 公式并升级 PowerShell：When new versions of PowerShell are released, update Homebrew's formulae and upgrade PowerShell:
brew update
brew upgrade powershell --cask
备注
可从 PowerShell (pwsh) 主机调用上面的命令，但是调用后必须退出 PowerShell 并重启以完成升级，并刷新 $PSVersionTable 中显示的值。The commands above can be called from within a PowerShell (pwsh) host, but then the PowerShell shell must be exited and restarted to complete the upgrade and refresh the values shown in $PSVersionTable.
通过 Homebrew 在 macOS 10.13 或更高版本上安装最新的预览版Installation of latest preview release via Homebrew on macOS 10.13 or higher
安装 Homebrew 后，可以安装 PowerShell。After you've installed Homebrew, you can install PowerShell. 首先，安装 Cask-Versions 包，通过它可安装替代版本的 cask 包：First, install the Cask-Versions package that lets you install alternative versions of cask packages:
brew tap homebrew/cask-versions
现在，可以开始安装 PowerShell：Now, you can install PowerShell:
brew cask install powershell-preview
最后，验证安装是否正常运行：Finally, verify that your install is working properly:
pwsh-preview
PowerShell 新版本发布后，更新 Homebrew 公式并升级 PowerShell：When new versions of PowerShell are released, update Homebrew's formulae and upgrade PowerShell:
brew update
brew upgrade powershell-preview --cask
备注
可能会从 PowerShell (pwsh) 主机调用上面的命令，但是调用后必须退出 PowerShell 并重新启动以完成升级。The commands above can be called from within a PowerShell (pwsh) host, but then the PowerShell shell must be exited and restarted to complete the upgrade.
然后刷新 $PSVersionTable 中显示的值。and refresh the values shown in $PSVersionTable.
稳定版本和 LTS 版本也支持使用 Homebrew tap 方法安装 PowerShell。Installing PowerShell using the Homebrew tap method is also supported for stable and LTS versions.
brew install powershell/tap/powershell
现在可以验证你的安装You can now verify your install
pwsh
发布新版本的 PowerShell 时，只需运行以下命令即可。When new versions of PowerShell are released, simply run the following command.
brew upgrade powershell
备注
无论使用 cask 还是 tap 方法，在更新到较新版本的 PowerShell 时，请使用最初安装 PowerShell 所使用的相同方法。Whether you use the cask or the tap method, when updating to a newer version of PowerShell, use the same method you used to initially install PowerShell. 如果使用其他方法，则打开新的 pwsh 会话时将继续使用较旧版本的 PowerShell。If you use a different method, opening a new pwsh session will continue to use the older version of PowerShell.
如果决定使用其他方法，可以使用 Homebrew link 方法来解决此问题。If you do decide to use different methods, there are ways to correct the issue using the Homebrew link method.
通过直接下载安装Installation via Direct Download
请从版本页中将 PKG 包 powershell-lts-7.0.3-osx-x64.pkg 下载到 CentOS 计算机。Download the PKG package powershell-lts-7.0.3-osx-x64.pkg from the releases page onto your macOS machine.
可以双击文件并按照提示操作，或者从终端安装：You can double-click the file and follow the prompts, or install it from the terminal:
sudo installer -pkg powershell-lts-7.0.3-osx-x64.pkg -target /
安装 OpenSSL.Install OpenSSL. PowerShell 远程处理和 CIM 操作均需要 OpenSSL。OpenSSL is needed for PowerShell remoting and CIM operations.
作为 .NET 全局工具安装Install as a .NET Global tool
如果你已安装 .NET Core SDK，则可以轻松地安装 PowerShell 作为 .NET 全局工具。If you already have the .NET Core SDK installed, it's easy to install PowerShell as a .NET Global tool.
dotnet tool install --global PowerShell
dotnet 工具安装程序将 ~/.dotnet/tools 添加到 PATH 环境变量中。The dotnet tool installer adds ~/.dotnet/tools to your PATH environment variable. 但是，当前运行的 shell 没有更新的 PATH。However, the currently running shell does not have the updated PATH. 应该可以通过键入 pwsh 从新 shell 启动 PowerShell。You should be able to start PowerShell from a new shell by typing pwsh.

安装依赖关系Installing dependencies
PowerShell 远程处理和 CIM 操作均需要 OpenSSL。OpenSSL is required for PowerShell remoting and CIM operations. 如有需要，可通过 MacPorts 安装 OpenSSL。You can install OpenSSL via MacPorts if needed.
备注
在同一系统上使用 MacPorts 和 Homebrew 时可能会出现问题。MacPorts and Homebrew can have problems when used to together on the same system. 但是，Homebrew 没有适用于 OpenSSL 1.0 的包。However, Homebrew does not have a package for OpenSSL 1.0. 有关详细信息，请参阅 MacPorts 常见问题解答。For more information, see the MacPorts FAQ.
安装 Xcode 命令行工具。Install the Xcode command-line tools. MacPorts 需要 Xcode 工具。The Xcode tools are required by MacPorts.
xcode-select --install安装 MacPorts。Install MacPorts. 如需说明，请参阅安装指南。If you need instructions, refer to the installation guide.
通过运行
sudo port selfupdate更新 MacPorts。Update MacPorts by runningsudo port selfupdate.通过运行
sudo port upgrade outdated升级 MacPorts 包。Upgrade MacPorts packages by runningsudo port upgrade outdated.通过运行

sudo mkdir -p /usr/local/opt/openssl sudo ln -s /opt/local/lib/openssl-1.0 /usr/local/opt/openssl/lib
卸载 PowerShellUninstalling PowerShell
如果使用 Homebrew 安装 PowerShell，请使用以下命令进行卸载：If you installed PowerShell with Homebrew, use the following command to uninstall:
brew cask uninstall powershell
如果通过直接下载安装 PowerShell，则必须手动删除 PowerShell：If you installed PowerShell via direct download, PowerShell must be removed manually:
sudo rm -rf /usr/local/bin/pwsh /usr/local/microsoft/powershell
若要删除其他 PowerShell 路径，请参阅本文档的路径一节，并使用 sudo rm 删除路径。To remove the additional PowerShell paths, refer to the paths section in this document and remove the paths using sudo rm.
备注
如果使用 Homebrew 安装，则此步骤并非必要步骤。This is not necessary if you installed with Homebrew.
路径Paths
$PSHOME是/usr/local/microsoft/powershell/7.0.3/$PSHOMEis/usr/local/microsoft/powershell/7.0.3/- 将从
~/.config/powershell/profile.ps1中读取用户配置文件User profiles will be read from~/.config/powershell/profile.ps1 - 将从
$PSHOME/profile.ps1中读取默认配置文件Default profiles will be read from$PSHOME/profile.ps1 - 将从
~/.local/share/powershell/Modules中读取用户模块User modules will be read from~/.local/share/powershell/Modules - 将从
/usr/local/share/powershell/Modules中读取共享模块Shared modules will be read from/usr/local/share/powershell/Modules - 将从
$PSHOME/Modules中读取默认模块Default modules will be read from$PSHOME/Modules - PSReadline 历史记录将记录到
~/.local/share/powershell/PSReadLine/ConsoleHost_history.txtPSReadline history will be recorded to~/.local/share/powershell/PSReadLine/ConsoleHost_history.txt
配置文件采用 PowerShell 的每个主机配置。The profiles respect PowerShell's per-host configuration. 因此主机特定的默认配置文件位于相同位置的 Microsoft.PowerShell_profile.ps1。So the default host-specific profile exists at Microsoft.PowerShell_profile.ps1 in the same locations.
PowerShell 采用 macOS 上的 XDG Base Directory 规范。PowerShell respects the XDG Base Directory Specification on macOS.
由于 macOS 派生自 BSD，因此前缀为 /usr/local而不是 /opt。Because macOS is a derivation of BSD, the prefix /usr/local is used instead of /opt. 因此，$PSHOME 是 /usr/local/microsoft/powershell/7.0.3/，且符号链接位于 /usr/local/bin/pwsh 中。So, $PSHOME is /usr/local/microsoft/powershell/7.0.3/, and the symbolic link is placed at /usr/local/bin/pwsh.
