Question

如何从src目录外导入模块？

./src/App.js
Module not found: Can't resolve 'material-ui' in '/Users/suvo/GitHub/portfolio/src'

根据react-material-icons页面，我应该按如下方式导入：

import mui from 'material-ui';

这个错误很奇怪。我在import $ from 'jquery';旁边得到了import mui...，它运行正常。还有什么，如果我创建一个新项目并添加 react-material-icons，npm不会开始，显示错误：

> myapp@0.1.0 start /Users/suvo/GitHub/myapp
> react-scripts start

sh: react-scripts: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! myapp@0.1.0 start: `react-scripts start`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the myapp@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

只需删除包名前面的.即可。

import mui from 'material-ui';

使用npm install或yarn install安装的软件包将保存到node_modules目录。您只需指定包名即可导入它们。

import React from 'react';
import mui from 'material-ui';

import AlarmIcon from 'react-material-icons/icons/action/alarm';

export default class Alarm extends React.Component {
  render() {
    return (
      <AlarmIcon/>
    );
  }
}

从node_modules导入模块（create-react-app）
