Question

当我尝试在现有 Angular project 中安装节点模块时遇到以下错误。我正在尝试在 Windows 机器（Win32 X64）中安装节点模块。

       > core-js@2.6.12 postinstall node_modules\babel-runtime\node_modules\core-js 
       > node -e "try{require('-/postinstall')}catch(e){}"

以下是我系统中安装的版本

  AngularCli : 8.3.29
  Node : 14.17.1
  NPM: 8.2.12

我尝试删除 node modules 文件夹并运行 npm cache clean --force 并重新安装 node modules ，还尝试卸载 nodejs 并删除 npm-cache 文件夹并重新安装。

我仍然面临同样的问题。任何帮助将不胜感激。

此错误意味着安装后脚本是 fork-and-exec'ing bash，Windows 上不存在该脚本。您需要从 MINGW64 (Git Bash) 之类的 Bash 模拟器中运行它。

因 core-js postinstall 脚本错误而失败
