eslint array-callback-return is invalid value warn is wrong type

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开始编辑代码，发现eslint报错：

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

所以我打开eslint.js 并找到了这条线

'array-callback-return': 'warn'

这对我来说似乎也是正确的。

还有其他我想检查的错误吗？或我需要更新的模块？

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 cmets 看到您正在使用 ESLint v1.7.3。在v2.0.0-alpha-1 中添加了array-callback-return，在v2.3.0 中添加了string severity levels ("off"/"warn"/"error")。至少升级到 v2.3.0 应该可以解决此问题。
