由于libcurl的源码编译因素，在安装pycurl可能会导致以下两种错误。

错误1：

ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)

错误2：

ImportError: pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)

解决办法：

错误1的解决办法如下：

# pip uninstall pycurl

# export PYCURL_SSL_LIBRARY=openssl

# pip install pycurl

错误2的解决办法如下：

# pip uninstall pycurl

# export PYCURL_SSL_LIBRARY=nss

# pip install pycurl

 

以下是网上一些更详细的解决办法

pip uninstall pycurl

export PYCURL_SSL_LIBRARY=[nss|openssl|ssl|gnutls]

pip install pycurl

#xor

curl -O https://pypi.python.org/packages/source/p/pycurl/pycurl-7.19.3.1.tar.gz

#...

python setup.py --with-[nss|openssl|ssl|gnutls] install
