eslint

The extension uses the ESLint library installed in the opened workspace folder. If the folder doesn't provide one the extension looks for a global install version.

If you haven't installed ESLint either locally or globally do so by running npm install eslint in the workspace folder for a local install

or npm install -g eslint for a global install.

On new folders you might also need to create a .eslintrc configuration file.

You can do this by either using the VS Code command Create ESLint configuration or by running the eslint command in a terminal.

If you have installed ESLint globally (see above) then run eslint --init in a terminal.

If you have installed ESLint locally then run .\node_modules\.bin\eslint --init under Windows and ./node_modules/.bin/eslint --init under Linux and Mac.

关于自动修复

现在代码都比较严格，可能包含缩进是 2 个空格，是否在语句最后加逗号的情况。不可能自己手动去一个个修正。 

eslint ./src --fix 

加上 --fix 可以自动修正一些明显的问题。 

配置 VS Code 自动修复，安装 ESLint VS Code 插件。 View -> Command Palette -> install extension. 

首选项 -> 设置 -> 搜索 "autofix". Auto Fix On Save。 就可以在保存的时候自动修正了。
