从node_modules导入模块（create-react-app） [英] Import module from node_modules (create-react-app)

问题描述

如何从src目录外部导入模块？

How do I import modules from outside src directory?

./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：

According to react-material-icons page, I was supposed to import as follows:

import mui from 'material-ui';

错误很奇怪。我从 jquery中获取了 import $； 紧挨 import mui ... ，而且效果很好。此外，如果我创建一个新项目并添加
react-material-icons，则npm将不会启动，并显示错误：

the error's strange. i got import $ from 'jquery'; just next to import mui... and it works fine. What's more, if i create a new project and add react-material-icons, the npm won't start, showing an error:

> 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:

推荐答案

只需删除软件包名称前面的。。

Just remove the . in front of the package name.

import mui from 'material-ui';

使用 npm install 或纱线安装保存到 node_modules 目录。您只需指定软件包名称即可导入它们。

Packages you install using npm install or yarn install are saved to node_modules directory. You can import them by just specifying package name.

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/>
    );
  }
}
