Failed to run task: 'bower --allow-root install' failed

问题

I am trying to build Apache zeppelin from the source code. But it breaks at the "zeppelin-web" with the following error

[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:0.0.23:bower (bower install) on project zeppelin-web: Failed to run task: 'bower --allow-root install' failed. (error code 8) -> [Help 1]

Here is the full debug log.

Apache zeppelin build process failure in zeppelin-web with bower http://madhukaudantha.blogspot.com/2015/04/building-zeppelin-in-windows-8.html

I was getting the same problem here, and this answer is just a guide, for those who are getting the same error: The maven output was similar to yours:

[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:0.0.25:bower (bower install) on project zeppelin-web: Failed to run task: 'bower --allow-root install' failed. (error code 1) -> [Help 1]

but going up a little bit it showed:

[ERROR] bower ECONFLICT Unable to find suitable version for angular

This means that bower was been executed but it couldn't choose between some available angular versions. To fix that I have gone to /zeppeling-root-folder/zeppelin-web and executed

./bower install

At the end of bower install it asked me to choose between one of the available angular versions, which I choose 1.5.0, after it just run a

npm install node-gyp@latest

This was an issue with apache zeppelin master branch. Now it is rectified. Just get the latest master branch and try build it
