我正在使用ng build --prod命令，但它显示错误

Answer 1

似乎是行节点缓存模块问题。请尝试以下命令：

cd {your-project}
npm -f cache clean 
rm -f package-lock.json
rm -rf node_modules
npm install

如果不起作用，请在主目录中清除.npm和.node-gyp。

Answer 2

你可以验证的东西很少，

1. 检查是否从正确的目录加载组件，我的意思是Import语句中组件的路径 import PackageName from './FromFolder';
2. 删除node_modules并重新安装所有软件包
3. 使用更新的软件包更新Angular CLI版本

现在试试ng build --prod
