Grunt Package cmd 在运行 minall 任务时失败（ubuntu 和 windows）

Question

我正在尝试按照本教程 https://docs.angularjs.org/misc/contribute 在我的操作系统上安装 angularJS，但我被困在这一步：

# Build AngularJS:
grunt package

当我执行“sudo grunt package”命令时，我得到了这个：

Running "bower" task

Running "clean:build" (clean) task
Cleaning build...OK

Running "clean:tmp" (clean) task
Cleaning tmp...OK

Running "buildall" task
>> File build/angular-scenario.js created.
>> File build/angular.js created.
>> File build/angular-loader.js created.
>> File build/angular-touch.js created.
>> File build/angular-mocks.js created.
>> File build/angular-sanitize.js created.
>> File build/angular-resource.js created.
>> File build/angular-messages.js created.
>> File build/angular-animate.js created.
>> File build/angular-route.js created.
>> File build/angular-cookies.js created.
>> File build/angular-aria.js created.
>> File tmp/promises-aplus-adapter++.js created.

Running "minall" task
ERROR - Cannot read: Needed

ERROR - Cannot read: a

ERROR - Cannot read: revision

ERROR - Cannot read: single

4 error(s), 0 warning(s)
Warning: Error minifying build/angular-animate.js Use --force to continue.

Aborted due to warnings.

我真的不明白是什么让 minall 失败了......

我正在做所有这一切，因为当启动业力时，我收到此错误：

$ karma start karma.conf.js 
INFO [karma]: Karma v0.12.24 server started at http://localhost:9876/
INFO [launcher]: Starting browser Chrome
INFO [Chrome 38.0.2125 (Linux)]: Connected on socket bMZ0eWE4QWE4XZTs0cny with id 13199010
Chrome 38.0.2125 (Linux) ERROR
  Uncaught ReferenceError: angular is not defined
  at /path/javascripts/app.js:1

我不走运吗？

感谢您的帮助！

我遇到了同样的问题。

这个问题/错误（？！）关于通过 git clone 或 bower install 安装 Angular 的区别。默认情况下，grunt package taks 尝试使用 git 命令来检测当前版本并提交 sha。但是，如果您使用 bower - 这是行不通的并会生成此类警告。

有我的解决方法：

找到./lib/versions/versions-info.js，然后转到getBuid()函数。

function getBuild() {
  var hash = shell.exec('git rev-parse --short HEAD', {silent: true}).output.replace('\n', '');
  if (hash.code === 0) { // just check code answer as in other places
    return 'sha.'+hash;  
  }
  return '';
}
