npm 安装期间的 node-sass 和 python 错误

Question

我无法运行项目，这是控制台日志，您能帮帮我吗？ 似乎 node-sass 和 Python 存在问题...... node-sass URL怎么可能是404...我不知道应该在哪里配置这个

$ npm install

> node scripts/install.js

Hint: If github.com is not accessible in your location
    try setting a proxy via HTTP_PROXY, e.g.

    export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

    npm config set proxy http://example.com:8080

我做了什么，我不确定是什么解决了这个问题，但现在它正在工作：

• 安装 Python 从https://www.python.org/downloads/windows/ 将 python 文件夹添加到您的 PATH，即 python/python39 中的一个，下载并安装适用于 Windows 的 python（接受添加到 PATH 的选项）。我还在自己的 windows env 变量中添加了其他变量名称 python2

• 重新安装Nodejs然后执行以下命令：

  • npm 链接@angular/cli
  • npm 重建 node-sass
  • npm --add-python-to-path='true' --debug install --global windows-build-tools
  • npm install --global node-gyp

最后我将一个新的 package.json 文件添加到我的 lib 项目中：

{
   "name": "menuT",
    "version": "1.0.0"
}

最后，我能够执行最后一个命令：

ng build menuT

我要救了……
