Reactjs 当eslint指控max length时，Prettier不适用。prettierignore不起作用

案例1（

PrintWidth

）：

这种情况下会发生以下情况：我在

.prettierrc

文件中、在vscode

settigns.json

和

.eslintrc.js

中配置了printWidth。但是，当达到

最大长度

（在本例中为

120

）时，

更漂亮的

不会应用其样式

案例2（

.prettierignore

）

prettier

只是忽略此文件，不应用其中包含的规则

当

eslint

验证代码是否处于行大小的限制（在本例中为120且大于限制）时，它会“中断”代码，例如降低

JSX组件的属性

等
