实践了网上的所有方法之后还是不起作用，最后更改为 yarn 来 install.

1. 安装 yarn 可以使用三种方式安装

1. 下载 .msi 文件安装
2. 通过 Chocolatey 安装
   需要先安装 Chocolatey : 控制台执行            
   @"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
   执行完之后执行 choco install yarn 
3. 通过 Scoop 安装 ：控制台执行
   iex (new-object net.webclient).downloadstring('https://get.scoop.sh')
   执行完之后执行：scoop install yarn
