Question

我有几天前从git hub克隆ng2-admin目录并运行npm install之后我能够运行并看到UI，现在我已经从ng2-admin删除了node_modules文件夹，docs文件夹和dist文件夹现在，在分散的用户界面的浏览器控制台中面临以下错误。

那么如何解决以下错误， `

Answer 1

解决方案非常简单。您需要在项目根目录中添加一个文件：

s = data_2.drop_duplicates(['patnum'])['vrddat']
print (s)
0   2012-01-31
1   2012-02-29
2   2012-03-31
Name: vrddat, dtype: datetime64[ns]

在内部，内容可以是：

postcss.config.js

_{这是Feng SHADU现已删除的非英语答案的翻译版本。}

Answer 2

如果您不想添加其他文件，只需在webpack配置中添加选项即可：

         {
           loader: `postcss-loader`,
           options: {
             options: {},
             plugins: () => {
               autoprefixer({ browsers: [ 'last 2 versions' ] });
             }
           }
         },

Answer 3

解决方案实际上是在这样的加载程序选项中正确引用配置文件（但是，如果还没有，请创建一个空文件）：

    {
      loader: 'postcss-loader',
      options: {
        config: { 
          path: 'path/to/postcss.config.js' 
        } 
      }
    }

您不应在node_modules文件夹中创建空的或虚拟的占位符配置。

Answer 4

使用内容module.exports = {}创建node_modules / bootstrap-loader / postcss.config.js;

Answer 5

这可能是由引用错误引起的，更具体地说是对不存在的CSS文件的导入。
