我刚刚在我的 Mac (OS X 10.12.6 - Sierra) 上下载了 stylelint (npm install -g stylelint) 并且基本上复制并尝试修改我在此处找到的示例配置文件。
然后我尝试在我拥有的 CSS 文件上运行它，在修复了 ~/.stylelintrc 文件中的一些错别字后，我得到了一个错误：
Error: Undefined rule null
at module.exports (/usr/local/lib/node_modules/stylelint/lib/utils/configurationError.js:8:28)
at Object.keys.forEach.ruleName (/usr/local/lib/node_modules/stylelint/lib/augmentConfig.js:302:13)
at Array.forEach (<anonymous>)
at normalizeAllRuleSettings (/usr/local/lib/node_modules/stylelint/lib/augmentConfig.js:297:29)
at augmentConfigBasic.then.then.then.augmentedConfig (/usr/local/lib/node_modules/stylelint/lib/augmentConfig.js:91:14)
at <anonymous>
我不知道该怎么做才能克服这个问题 - 我不想尝试调试代码（我在调试自己的代码时遇到了很多问题，我希望这个工具能帮助我 - 我没有足够的带宽来尝试调试别人的代码）
帮助？
更新：根据要求 - 我的 ~/.stylelintrc 文件：
