node.js - fatal error : Unable to find Gruntfile

Question

咕噜--版本

grunt-cli v0.1.8
grunt v0.4.1

$ npm -v

1.2.18

$ Node -v

v0.10.6

当我运行 grunt init 来创建 Gruntfile.js 时，出现错误:

$ grunt init 
A valid Gruntfile could not be found. Please see the getting started guide for
more information on how to configure grunt: http://gruntjs.com/getting-started
Fatal error: Unable to find Gruntfile.

我搜索了 Grunfile.js，得到:

/home/ka/.npm/grunt-cli/0.1.8/package/Gruntfile.js
/home/ka/tmp/npm-1464/1368671910572-0.38816986070014536/package/Gruntfile.js

/root/.npm/grunt/0.4.1/package/Gruntfile.js
/root/.npm/grunt-cli/0.1.8/package/Gruntfile.js

我可以将这些 grunt 文件之一复制到/ex/co/www/dev/htdocs/unittest(Javascript/quint 测试所在的位置)吗？还是我还缺少其他东西？

我正在尝试在 Centos 6.4 上运行 grunt。另外，为什么 grunt init 不创建 Gruntfile.js？

cp /root/.npm/grunt/0.4.1/package/Gruntfile.js /ex/co/www/dev/htdocs/unittest/

我按原样复制了它，现在我得到了更好的错误:

Answer 1

我认为您正在寻找的是在 Project Scaffolding 中找到的实际命令行工具 grunt-init文档。

您当前的命令 grunt init 正在寻找 Gruntfile.js 和其中的任务 init。显然无法找到您的 Gruntfile.js 所以抛出该错误。

编辑:

您的新错误是因为您复制了一个 Gruntfile.js 文件，并且 default 任务(如果您想打开它可以在底部附近找到)将调用那些模块。通常你会使用类似 bower 的东西将它们安装到你的本地目录中。

我上面提到的您的默认任务将如下所示:

grunt.registerTask('default', ['jshint', 'qunit', 'concat', 'uglify']);

这基本上是说:当我在命令行运行 grunt 时，运行任务 jshint、qunit、concat 和 uglify 的顺序。这些任务将在之前的 Gruntfile 中指定。要了解该文件，请查看 sample Gruntfile .

我建议您看看Yeoman因为它是一个很好的工具，可以为您的应用程序提供脚手架(包括工作的 Gruntfile.js)。

编辑 2:

了解正在发生的事情很重要。您复制的 Gruntfile.js 看起来正在调用“subgrunt”任务。即子项目中的 grunt 任务。这是你想要的吗？

按照您的 Gruntfile.js - 当您运行 grunt 时，它会调用以下顺序:'jshint', 'nodeunit', 'subgrunt'。

理想情况下，您想自己编写而不是复制它，因为 jshint 调用了一些我不熟悉的选项。如果您阅读 jshint documentation它没有提到前三个选项。

我认为你应该尝试这样的事情:

jshint: {
  options: {
    curly: true,
    eqeqeq: true,
    immed: true,
    latedef: true,
    newcap: true,
    noarg: true,
    sub: true,
    undef: true,
    unused: true,
    boss: true,
    eqnull: true,
    node: true,
    es5: true
  }
  files: {
    src: ['path/to/your/*.js', 'another/path/to/your/*.js']
  }
}

您应该通读每项任务的文档，并确保您了解所传递的选项。

另一个提示。如果您看到如下文件引用:

 <%= jshint.gruntfile %>

这是对 Gruntfile.js 中特定文件/属性集的引用。在这种情况下，这来自 watch 任务并指向 jshint.gruntfile 属性作为要监视的文件。
