pycurl对libcurl版本有要求，需先升级curl


下载curl
wget http://curl.haxx.se/download/curl-7.21.3.tar.gz
tar xzvf curl-7.21.3.tar.gz
cd curl-7.21.3
./configure #假若指定路径后面安装pycurl也同样需要指定curl-config路径，指到文件
make
make install


下载pycurl
wget http://pycurl.sourceforge.net/download/pycurl-7.19.0.tar.gz
tar xzvf pycurl-7.19.0.tar.gz
cd pycurl-7.19.0
python setup.py install


一切顺利，一个错误都没有提示，但运行python之后，出了问题

import pycurl


提示如下错误

Traceback (most recent call last):
File “”, line 1, in ?
ImportError: No module named pycurl



检查一下，原来是pycurl自己假定的curl路径不对。
需要给pycurl指定curl-config 路径，如下所示：

python setup.py install –curl-config=/usr/local/bin/curl-config






相关报错：


Traceback (most recent call last):
  File "", line 1, in
ImportError: libcurl.so.4: cannot open shared object file: No such file or directory
或者
Traceback (most recent call last):
  File "", line 1, in
ImportError: pycurl: libcurl link-time version (7.19.7) is older than compile-time version (7.37.0)


提示错误，解决方法：

export LD_LIBRARY_PATH=/usr/local/lib


or

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
