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

今天在linux机器上执行yum指令时报“pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (none/other)”找个错误，提示pycurl不存在。既然不存在，那就安装呗。使用

pip install pycurl安装过程报错，提示缺少某些模块，具体如下

src/module.c: In function ‘initpycurl’:       src/module.c:723: error: ‘CURLPROTO_IMAP’ undeclared (first use in this function)       src/module.c:723: error: (Each undeclared identifier is reported only once       src/module.c:723: error: for each function it appears in.)       src/module.c:724: error: ‘CURLPROTO_IMAPS’ undeclared (first use in this function)       src/module.c:725: error: ‘CURLPROTO_POP3’ undeclared (first use in this function)       src/module.c:726: error: ‘CURLPROTO_POP3S’ undeclared (first use in this function)       src/module.c:727: error: ‘CURLPROTO_SMTP’ undeclared (first use in this function)       src/module.c:728: error: ‘CURLPROTO_SMTPS’ undeclared (first use in this function)       src/module.c:729: error: ‘CURLPROTO_RTSP’ undeclared (first use in this function)       src/module.c:730: error: ‘CURLPROTO_RTMP’ undeclared (first use in this function)       src/module.c:731: error: ‘CURLPROTO_RTMPT’ undeclared (first use in this function)       src/module.c:732: error: ‘CURLPROTO_RTMPE’ undeclared (first use in this function)       src/module.c:733: error: ‘CURLPROTO_RTMPTE’ undeclared (first use in this function)       src/module.c:734: error: ‘CURLPROTO_RTMPS’ undeclared (first use in this function)       src/module.c:735: error: ‘CURLPROTO_RTMPTS’ undeclared (first use in thi

本人参考http://stackoverflow.com/questions/26405389/failed-to-install-pycurl-on-heroku来解决

pip install pycurl==7.19.3.1提示安装成功，但是在使用

import pycurl时还是报错，于是本人下载了libcurl库，下载链接：http://curl.haxx.se/download.html

下载后解压，.然后

/configure

make

之后还是报错，搜索后，找到了解决方案，按照这里介绍http://curl.haxx.se/mail/lib-2008-06/0331.html，Just build it with NSS instead of OpenSSL:配置时加上参数

 $ ./configure --without-ssl --with-nss 这样就完美的解决了
