NPM和Eslint：这令人困惑，这正常吗？

Question

我是JS的新手，我正在尝试学习棉绒。因此，我正在关注一个教程，其中我们在lint文件中设置了package.json阶段。

它看起来像这样："lint": "./node_modules/.bin/eslint ."

因此，在终端中，当我运行./node_modules/.bin/eslint .时，它会按预期报告所有错误和警告。

/Users/me/dev/webapps/templates/sample_node_project/index.js
  1:1   error    Expected 1 empty line after require statement not followed by another require  import/newline-after-import
  1:35  error    Missing semicolon                                                              semi
  5:27  error    Missing semicolon                                                              semi
  9:3   warning  Unexpected console statement                                                   no-console
  9:53  error    Missing semicolon                                                              semi

✖ 5 problems (4 errors, 1 warning)
  4 errors and 0 warnings potentially fixable with the `--fix` option.

但是当我运行npm run lint时，我得到的是：

/Users/me/dev/webapps/templates/sample_node_project/index.js
  1:1   error    Expected 1 empty line after require statement not followed by another require  import/newline-after-import
  1:35  error    Missing semicolon                                                              semi
  5:27  error    Missing semicolon                                                              semi
  9:3   warning  Unexpected console statement                                                   no-console
  9:53  error    Missing semicolon                                                              semi

✖ 5 problems (4 errors, 1 warning)

因此，这引发了额外的错误，使我认为我的node和npm已损坏。另外，在本教程中，讲师正在运行yarn lint，而他似乎得到的额外错误块要少得多。

那正常吗？

Ico1将消除您看到的NPM错误。由于发生lint错误，ESLint为您提供了非零的退出代码。 NPM基本上说它由于掉毛错误而无法正确运行。是的，这很正常。
