致命错误:无法找到Gruntfile

时间:2013-05-17 14:13:51

标签: node.js gruntjs

grunt --version

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,我收到错误:

$ 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,我得到了:

/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

我可以将其中一个grunt文件复制到/ ex / co / www / dev / htdocs / unittest(Javascript / quint测试的地方)吗?或者还有其他我想念的东西?

我正试图在Centos 6.4上运行grunt。另外,为什么不grunt init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:

grunt

我遇到了同样的错误,事实证明我只需要先运行npm install。虽然我之前已经安装了npm,但是安装后某些东西已经损坏了。快速重新安装工作;我只需要这两个命令:

npm install
grunt jshint

我认为您正在寻找的是Project Scaffolding文档中的实际命令行工具grunt-init

您当前的命令grunt init正在寻找Gruntfile.js及其中的任务init。显然无法找到您的Gruntfile.js,因此会抛出该错误。

编辑:

您的新错误是因为您复制了Gruntfile.js文件而default任务(如果要打开它,则位于底部附近)将调用这些模块。通常,您将使用bower之类的东西将它们安装到本地目录中。

我上面提到的默认任务看起来像这样:

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

这基本上是说:当我在命令行运行grunt时,按顺序运行任务jshintqunitconcatuglify 。这些任务早先已在Gruntfile中指定。要了解该文件,请查看sample Gruntfile

我建议您查看Yeoman,因为它是为您的应用提供脚手架的好工具(包括工作Gruntfile.js)。

编辑2:

了解发生的事情非常重要。您复制的Gruntfile.js看起来就是在调用“subgrunt”任务。即子项目中的grunt个任务。这是你想要的吗?

完成Gruntfile.js之后 - 当您运行grunt时,它会调用以下订单:'jshint', 'nodeunit', 'subgrunt'

理想情况下,你想自己写这个而不是复制它,因为我不熟悉jshint调用的一些选项。如果您阅读jshint documentation,则不会提及前三个选项。

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']
  }
}

您应该仔细阅读每个任务的文档,并确保了解所传递的选项。

另一个暗示。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。

我有类似的问题,我使用了以下命令,它对我有用

grunt -f 
grunt server

希望它也适合你。

答案 3 :(得分:0)

Grunt文件应位于根目录中,而不应位于文件夹内的某个位置,并且应拼写“ Gruntfile.js”

示例

对于asp.net Core角度项目,其位置应为

enter image description here

如果您将此文件放在ClientApp或其他位置,直到您定义某种方法来执行此操作,否则将无法正常工作。

检查你是否正在和你一起工作 运行npm install那里可能会解决你的问题
