Linux下遇到PyCurl的错误解决方法(解决方法错误)

Could not run curl-config 的解决方式

Downloading/unpacking pycurl (from pyspider)
 Downloading pycurl-7.19.5.1.tar.gz (142kB): 142kB downloaded
 Running setup.py (path:/tmp/pip-build-DuBGJ5/pycurl/setup.py) egg_info for package pycurl

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-DuBGJ5/pycurl
Storing debug log for failure in /root/.pip/pip.log

在安装 pyspider 的时候我就遇到了这个问题， pyspider 依赖 pycurl 这个库，而 pycurl 要求系统中存在相对应的库。

经过我的测试， curl 是正确安装了的，但是却依然提示了找不到 curl-config 的问题
