问题:pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
原因:没有ssl模块
解决:
yum install openssl
yum install openssl-devel -y
修改Modules/Setup.dist,去掉这几行注释
205 _socket socketmodule.c
206
207 # Socket module helper for SSL support; you must comment out the other
208 # socket line above, and possibly edit the SSL variable:
209 SSL=/usr/local/ssl
210 _ssl _ssl.c \
211 -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
212 -L$(SSL)/lib -lssl -lcrypto
再重新编译
./configure
make
make install
