Question

我已经在默认网站上安装了node / npm / vue.js-cli。

我安装了这两个扩展程序：

保存时，会检查ESlint规则并显示错误：

问题是，当我按CTRL-SHIFT-F格式化代码时，它（1）从函数名和括号之间取出空格，但是当我保存时文件，ESLint（2）抱怨空间不存在。

我如何知道哪些工具/扩展程序正在格式化我的代码？
我保存时如何知道检查规则的工具/扩展名是什么？
如何设置它们以使它们相同，以便重新格式化我的代码会将代码更改为它在保存时检查的规则？

当我在vue.js中启动仪表板构建时，我遇到了同样的问题。最终我上网至少2-3个小时。我发现了一个开发代码，它有.eslintrc文件和package.json的完美配置，包括所有babel核心包。

.eslintrc文件 -
