尝试使用以下食谱在CentOS 6计算机上安装和运行Python 3.7.2：
yum -y update
yum install gcc
yum groupinstall -y "development tools"
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel libffi-devel
wget http://python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz
tar -xf Python-3.7.2.tar.xz
cd Python-3.7.2
./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
安装一切正常。但是，一旦我尝试首先使用pip安装任何python软件包...
pip3.7 install requests
我得到了错误：
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting requests

没有意义，因为您安装了SSL模块，如您所见：
[root@xxx Python-3.7.2]# rpm -qa | grep openssl
openssl-1.0.1e-57.el6.x86_64
openssl-devel-1.0.1e-57.el6.x86_64
已经尝试了一切并搜索了吨，如何解决这个问题？
