1.安装python3.7以及pip3

1)首先来安装依赖

yum -y install gcc gcc-c++ yum -y groupinstall “Development tools” yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel libffi-devel

2)然后下载 Python-3.7.0 的源码并解压：

mkdir -p ~/src cd ~/src wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz tar -zxvf Python-3.7.0.tgz

3)编译安装：

cd Python-3.7.0 ./configure –prefix=/usr/local/python3 make && make install

4)最后创建软链接

ln -s /usr/local/python3/bin/python3 /usr/bin/python3 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

5)测试

python3 --version pip3 --version

升级pip3命令：

pip3 install –upgrade pip

2.使用pip3安装pipenv时pip报错

安装指令：

pip3 install pipenv

错误信息：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

原因：
yum 安装的openssl 版本都比较低，即pip依赖出现问题，导致pip未够正常使用，需要更新依赖！

3.使用pip3安装pipenv时出现ReadTimeoutError

安装指令：

pip3 install pipenv

错误信息（此时简略错误信息）：

ReadTimeoutError

解决方案：
使用以下指令：

pip3 --default-timeout=100 install pipenv

4.查看pipenv版本报错

[root@instance-6lf3j8lp Python-3.7.0]# pipenv --version -bash: pipenv: command not found

原因：未建立软链接
解决方案：

ln -s /usr/local/python3/bin/pipenv /usr/bin/pipenv
