Unable to build AngularJS using grunt

Question

I'm new to AngularJS. I'm installing the AngularJS and stuck at following step:

grunt package.

Error is as follows:

Running tasks: package
Warning: Task "package" not found. Use --force to continue.

Aborted due to warnings.

Any inputs would be helpful.

Answer 1

You should set environment variable NG1_BUILD_NO_REMOTE_VERSION_REQUESTS at first. For example, in Windows:

set NG1_BUILD_NO_REMOTE_VERSION_REQUESTS=1

I also met this problem like this:

CDN version (remote): No version found. Current version (remote): v1.5.7 Loading "Gruntfile.js" tasks...ERROR
>> Error: Unable to read CDN version, are you offline or has the CDN not been properly pushed? Warning: Task "package" not found. Use
--force to continue.

Aborted due to warnings.

I checked the angular's source code ,Found in the 'Gruntfile.js' ,line20 it throw the Error

Unable to read CDN version, are you offline or has the CDN not been properly pushed?

, so comment this code to solve your problem.

  //if (versionInfo.cdnVersion == null) {
  //  throw new Error('Unable to read CDN version, are you offline or has the CDN not been properly pushed?');
  //}

this can make the building success.
