webpack - eslint array-callback-return 是无效值 warn 是错误的类型

Question

我使用 create-react-app ( https://facebook.github.io/react/blog/2016/07/22/create-apps-with-no-configuration.html ) 创建了一个 SPA，没有任何问题

然后我启动 ATOM 并开始编辑代码，发现 eslint 出现错误:

Configuration for rule "array-callback-return" is invalid: value "warn" is the wrong type

所以我打开了eslint.js并找到了这一行

'array-callback-return': 'warn'

这对我来说似乎也是正确的。

还有其他我错过检查的错误吗？或者我需要更新的模块？

更新:这是错误日志

Error: /Users/Jim/Project/tomorrow/config/eslint.js:

我的 Atom 使用 linter-eslint 包，我怀疑某些设置可能是原因

我从评论中看到您正在使用 ESLint v1.7.3。 array-callback-return已添加于 v2.0.0-alpha-1 ，和string severity levels (“关闭”/“警告”/“错误”)已添加到 v2.3.0 。升级到至少 v2.3.0 应该可以解决该问题。
