Answer 1

如果尚未下载，请下载Microsoft Build Tools。

该错误表明cl.exe is not found。如果已安装，请转至程序和功能并修复工具。

来源：python pip on Windows - command 'cl.exe' failed

您需要在计算机和cl.exe中安装PATH（Microsoft C编译器）。 PATH是一个环境变量，它告诉Windows在哪里找到可执行文件。

首先，确保已安装用于Visual Studio的 C ++生成工具。您可以与Visual Studio downloads page分开下载 Visual Studio的构建工具，然后从安装程序中选择 C ++的构建工具。如果已经拥有Visual Studio，则还可以从Visual Studio安装程序中安装使用C ++进行桌面开发，您应该在“开始”菜单中安装该软件。

然后，使用正常菜单中的 Visual Studio文件夹中的特殊命令提示符之一，而不是普通的命令提示符或PowerShell 。对于32位Python，您可能正在寻找 x86本机工具命令提示符。这样会自动设置PATH，以便可以找到cl.exe。
