Webstorm下安装ESLint检测JS代码

今天配置下Webstorm下面的Eslint。

1，先看下本地安装的Node，NPM版本，2017-11-23日这个节点最新版本。

>node -v

v8.9.1

>npm -v

5.5.

2，使用Webstorm快捷键Alt + F12，进入Terminal窗口，如下图

3，执行全局安装eslint

npm install -g eslint

4，执行 eslint --init

初始化eslint配置文件,每一步根据自己需要选择YES or NO，

C:\Users\XXXXXXX\WebstormProjects\es6tutorial>eslint --init

? How would you like to configure ESLint? Answer questions about your style

? Are you using ECMAScript  features? Yes

? Are you using ES6 modules? Yes

? Where will your code run? Browser

? Do you use CommonJS? No

? Do you use JSX? No

? What style of indentation do you use? Tabs

? What quotes do you use for strings? Single

? What line endings do you use? Unix

? Do you require semicolons? Yes

? What format do you want your config file to be in? JavaScript

最后将会生成一份.eslintrc.js 文件,

5，在自己项目里，执行 eslint learning/chap02-let.js，

eslint将会根据配置的规则进行JS验证并在控制台打印出提示消息

PS：我在安装测试过程中，发生如下错误，大概意思是：要确保ESLint全局安装。

Oops! Something went wrong! :(

ESLint: 4.11..

ESLint couldn't find the plugin "eslint-plugin-jsx-a11y". This can happen for a couple different reasons:

. If ESLint is installed globally, then make sure eslint-plugin-jsx-a11y is also installed globally. A globally-installed ESLint cannot find a

locally-installed plugin.

. If ESLint is installed locally, then it's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

    npm i eslint-plugin-jsx-a11y@latest --save-dev

If you still can't figure out the problem, please stop by https://gitter.im/eslint/eslint to chat with the team.
