在Centos中，我尝试使用Python2.7进行./configure，然后遇到此问题
有关更多详细信息，请参见" config.log"
This file contains any messages produced by compilers
while running configure, to aid debugging if configure makes a mistake.
It was created by python configure 2.7, which was
generated by GNU Autoconf 2.69. Invocation command line was
$ ./configure

c编译器无法创建可执行文件
那是关于GCC缺失的文件。您将使用＃ yum install gcc-c++
即。GCC-C 的安装还将安装以下内容：{libc-devel，glibc-headers，kernel-headers} ... to/usr/include/include/，/usr/lib64/。否则没有完全工作的海湾cc。
P.S。：系统python无法手动更换，更改或更新。.所有管理工具{yum，system-config-*}将停止工作。
但是，您可以1）将新的Python安装到隐藏的位置，例如/opt/python27/。
或2）添加scl repo https://wiki.centos.org/additionalresources/repositories/scl ...和get/opt/opt/rh/python27/：包装列表在这里http：//mirror.centos.centos.centos.centos.centos.centos.centos.centos.centos.org/centos-6/6.8/sclo/x86_64/rh/python27/
