I have clone ng2-admin directory from git hub few days back and run npm install after that i am able to run and see the UI, now I had been deleted node_modules folder, docs folder, and dist folder from ng2-admin now facing below error in browser console with scattered UI.

回答1:


The solution is very simple. You need to add a file on your project root directory:

postcss.config.js

Inside, the content can be:

module.exports = {};

This is a translated version of a now-deleted non-English answer by Feng SHADU.




回答2:


If you don't want to add another file, it's enough to add your options in your webpack config:

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



回答3:


The solution is actually to properly reference the config file in the loader options like this (create an empty one if you don't have it yet, though):

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

You are not supposed to create empty or dummy placeholder configs in the node_modules folders.




回答4:


Create node_modules/bootstrap-loader/postcss.config.js with the contents module.exports={};




回答5:


This can be caused by a reference error, more specifically an import for CSS file that doesn't exist.
