npm无法安装量角器或selenium-webdriver-> gyp ERR！ 建立错误

Question

For an Angular project I wrote some E2E test and I would like to test them, but I cannot install protractor or selenium-webdriver, I get the error message:

gyp ERR! build error 
gyp ERR! stack Error: `make` failed with exit code: 2
gyp ERR! stack     at ChildProcess.onExit (/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/build.js:269:23)
gyp ERR! stack     at ChildProcess.emit (events.js:110:17)

gyp ERR! node -v v0.12.4
gyp ERR! node-gyp -v v2.0.2
gyp ERR! not ok 

I have searched this error on stackoverflow and github, but haven't come closer to getting past this error.

I am using npm -v 2.14.0 on Ubuntu 15.04. The gyp dependencies are met: Python 2.7.9, make and gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)

Answer 1

After reading npm install, node-gyp build error on only one of two identical machines I tried these three commands:

$ npm cache clean
$ rm -rf node_modules
$ rm -rf ~/.node-gyp

And after that was able to npm install -g protractor so found an answer myself.
