当我尝试使用 Grunt 进行编译时出现此错误。我以前没怎么用过它，但我似乎只在这个项目中遇到了这个错误，它适用于我服务器上的其他项目。

运行“jshint:main”（jshint）任务警告：路径必须是字符串。收到 null 使用 --force 继续。

由于警告而中止。

reporterOutput必须是字符串。当省略时，它被视为一个null.

在 Gruntfile.js 中为其提供一个空字符串

jshint: {
    main: 'script/dist/main.js',
    reporterOutput: '' // <-- Add an empty String here
}

如果您使用任何生成器，请像这样

jshint: {
      main: {
        options: {
            jshintrc: '.jshintrc',
            reporterOutput: "" // Empty string inside options
        },
        src: createFolderGlobs('*.js')
      }
    }

对我来说，它在配置对象中添加reporterOutput了一个空字符串值，例如：Gruntfile.js

{
  jshint: {
     options: {
        jshintrc: ".jshintrc",
        reporterOutput: ''
     }
  }
}

解决了它。

此错误与jshint库的版本有关。要解决，请将当前 jshint 版本更改为最新

$ npm install grunt-contrib-jshint@latest --save-dev

无论如何，手动将文件jshint中的版本更改为 1.1.0。package.json不要忘记使用以下语句更新项目：

npm install
