eslint-plugin-react 需要 eslint 的同伴吗？

Question

我正在尝试在 Atom 编辑器上为 ReactJS 设置 eslint，所以我遵循提供的答案 :

但是，当我尝试安装 eslint-plugin-react 时，我收到警告：

eslint-plugin-react@7.7.0 需要 eslint@^3.0.0 的对等体 || ^4.0.0 但已安装 none。您必须自己安装对等依赖项。

目前安装的是eslint v4.19.1版本，我不知道是否需要降级我的eslint，因为我仍然收到JSX代码的错误

..

return (
      <div className="App">

...

错误：

Parsing error: Unexpected token < (Fatal)

Answer 1

我过去也遇到过问题。这是我为 React & Atom 设置 eslint 的方式。也可能对您有用（我知道您可能不需要某些软件包 - 留给您）：

npm install -g create-react-app

create-react-app my-app
cd my-app

npm install --save-dev eslint babel-eslint eslint-plugin-react eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-flowtype  eslint-plugin-html eslint-config-jquery eslint-plugin-jquery prop-types

npm install --save react

Atom 中安装的 eslint 包：

linter-csslint
linter-eslint
linter-stylelint

这是我的 .eslintrc:
