Can't connect to HTTPS URL because the SSL module is not available

python3.5.9源码安装ssl路径问题

问题来源：安装好的python3使用pip3 install 会报Can't connect to HTTPS URL because the SSL module is not available

问题分析：查找网上的解答后会发现是python编译的时候没有设置ssl
，有解决方案是在./configure --with-ssl，然而其实根本没有这个参数

问题解决：

• 首先安装ssl这个在很多教程中都有，建议源码安装

• 然后找到ssl的include和lib路径，一般在/usr/local/include和/usr/local/lib

• 然后修改python安装包下的setup.py中 ：
  /usr/local/ssl/include ----> /usr/local/include
  /usr/local/ssl/lib ----> /usr/local/lib
  修改后如下：

    # Detect SSL support for the socket module (via _ssl)
    search_for_ssl_incs_in = [
                          '/usr/local/include',
                          '/usr/contrib/ssl/include/'
                         ]
    ssl_incs = find_file('openssl/ssl.h', inc_dirs,
                         search_for_ssl_incs_in
                         )
    if ssl_incs is not None:
        krb5_h = find_file('krb5.h', inc_dirs,
                           ['/usr/kerberos/include'])
        if krb5_h:
            ssl_incs += krb5_h
    ssl_libs = find_library_file(self.compiler, 'ssl',lib_dirs,
                                 ['/usr/local/lib',
                                  '/usr/contrib/ssl/lib/'
                                 ] )
  

• 然后再执行

./configure
make -j$(pronc)
make test  -j$(pronc)
sudo make install

• 最后查看是否安装完成

python3
import ssl
