无法在 windows 10 上安装纱线

Question

我安装了 node v16.13.0、npm v8.1.0 java 1.8 版。0_211 我想我也安装了 yarn，但我试图使用 yarn global add expo-cli 安装 expo我得到：

yarn : File C:\Program Files\nodejs\yarn.ps1 cannot be loaded. The file C:\Program Files\nodejs\yarn.ps1 is not
digitally signed. You cannot run this script on the current system. For more information about running scripts and
setting execution policy, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

+ yarn global add expo-cli
+ ~~~~
    + CategoryInfo          : SecurityError: (:) [], PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess

然后又尝试安装yarn，现在100%无法安装：

PS C:\Users\user> npm install -g yarn

changed 1 package, and audited 2 packages in 1s

found 0 vulnerabilities

但是运行 yarn --version 我得到了和以前一样的错误：

yarn : File C:\Program Files\nodejs\yarn.ps1 cannot be loaded. The file C:\Program Files\nodejs\yarn.ps1 is not
digitally signed. You cannot run this script on the current system. For more information about running scripts and
