致命错误:无法找到Gruntfile

Question

grunt --version

grunt-cli v0.1.8
grunt v0.4.1

$ npm -v

1.2.18

$ node -v

v0.10.6

当我跑来grunt init创建时Gruntfile.js,我得到错误:

$ 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.

我搜索过Grunfile.js,我得到:

/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？

我试图在Centos 6.4上运行grunt.另外,为什么不grunt init创造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

>> Local Npm module "grunt-contrib-watch" not found. Is it installed?

模式进展....

Answer 1

我认为你在寻找什么是实际的命令行工具grunt-init中发现的工程脚手架文档.

您当前的命令grunt init正在查找其中Gruntfile.js的任务和任务init.它显然无法找到你Gruntfile.js所以抛出那个错误.

编辑:

您的新错误是因为您已经复制了一个Gruntfile.js文件而且该default任务(如果您想打开它,则位于底部附近)将调用这些模块.通常,您将使用类似的东西bower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:当我运行grunt在命令行,运行任务jshint,qunit,concat并uglify按此顺序.这些任务将在之前的版本中指定Gruntfile.要了解该文件,请查看示例Gruntfile.

我可以建议看看Yeoman,因为它是一个很棒的工具,可以为您的应用程序提供脚手架(包括工作Gruntfile.js).

编辑2:

了解发生的事情非常重要.在Gruntfile.js你复制看起来是叫"subgrunt"任务.即grunt子项目中的任务.这是你想要的吗？

通过你的Gruntfile.js- 当你运行grunt它时,调用以下顺序:'jshint', 'nodeunit', 'subgrunt'.

理想情况下,你想自己写这个而不是复制它,因为jshint我不熟悉一些选项.如果你阅读jshint文档,它没有提到前三个选项.

我想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']
  }
}

您应该阅读每个任务的文档,并确保了解您要通过的选项.

另一个提示.如果您看到如下所示的文件引用:

 <%= jshint.gruntfile %>

这是对特定文件/属性集的引用Gruntfile.js.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.

我有同样的错误,结果我只需要先运行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; 我需要的只是这两个命令:

npm install
grunt jshint
