python学习笔记--pycurl模块安装遇到的问题。

1.用easy_install安装的时候

[root@idayuan ~]# easy_install pycurl
Searching for pycurl
Best match: pycurl 7.19.
Adding pycurl 7.19. to easy-install.pth file

Using /usr/lib64/python2./site-packages
Processing dependencies for pycurl
Finished processing dependencies for pycurl

2.用pip安装的时候（由于已经安装完成所以只摘取了一些错误）

__main__.ConfigurationError: Could not run curl-config: [Errno ] No such file or directory

解决办法：

[root@idayuan ~]# yum install libcurl-devel

二。安装python-rrdtool时遇到的一些问题。

make me happy. Go to http://tobi.oetiker.ch/wish and
place an order.
