npm http 200 https://registry.npmjs.org/phantomjs/-/phantomjs-1.9.7-15.tgz
npm ERR! cb() never called!
npm ERR! not ok code 0

[root@dev ~]# node -v

[root@dev ~]# npm -v

操作系统：centOS 6.2（最终版）

有什么问题？如何在centOS 6.2上安装phantomjs？

Answer 1

根据这个：http://phantomjs.org/build.html

sudo yum install gcc gcc-c++ make git openssl-devel freetype-devel fontconfig-devel
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.9
./build.sh

你也可以尝试预编译版本，它会快得多：

http://phantomjs.org/download.html

希望它有所帮助！

由于版本已大大提升，您可能不会再出现此错误。但是，如果任何人在运行phantomJS的CentOS 6上有错误，我发现http://www.sameerhalai.com/blog/how-to-install-phantomjs-on-a-centos-server/有帮助并解决了我的问题。即，grunt test产生了：

-sh-4.1$ grunt test
Running "karma:unit" (karma) task
INFO [karma]: Karma v0.12.28 server started at http://localhost:9876/
INFO [launcher]: Starting browser PhantomJS
ERROR [launcher]: Cannot start PhantomJS

INFO [launcher]: Trying to start PhantomJS again (1/2).
ERROR [launcher]: Cannot start PhantomJS

INFO [launcher]: Trying to start PhantomJS again (2/2).
ERROR [launcher]: Cannot start PhantomJS

ERROR [launcher]: PhantomJS failed 2 times (cannot start). Giving up.
Warning: Task "karma:unit" failed. Use --force to continue.

Aborted due to warnings.

但是

之后

yum install -y freetype fontconfig

PhantomJS开始工作，测试通过了：）
