我在安装 Azure CLI 时遇到问题。我尝试了三种方法，但都失败了。
前两个来自在 Windows 上安装 Azure CLI， 我试过了
- 使用 PowerShell 安装 Azure CLI，并
- 自行下载并安装最新版本的 Azure CLI .msi 文件。
- 我也尝试过删除它并使用.msi 文件重新安装。
但在所有情况下，如果我输入az，我会得到
az : The term 'az' is not recognized as the name of a cmdlet, function, script file, or operable program.
然后我尝试在 Linux 上安装 Azure CLI作为最后的手段，但它也失败了：
+ echo 'deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ bullseye main'
+ apt-get update

在 Windows 上，你可以找到 Azure CLI命令这里：
C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\wbin
该路径可以在环境变量中找到Path：
电源外壳：
$Env:Path
C:\Program 文件（x86）\Microsoft SDKs\Azure\CLI2\wbin；
如果使用 msi 文件安装 Azure CLI，它将安装应用程序并将位置添加到Path变量。
如果打开了 PowerShell，则Path不会在后台自动刷新。您必须关闭 PowerShell 并打开新会话。通常，Path会加载更新。此行为也适用于更多应用程序。
因此，重新启动机器可能是有意义的（或者如果你想要安全起见）。
顺便说一句：也可以在 Windows 11 中刷新环境变量（无需重启）例如 Chocolatey
