# 若下载失败则手动下载上传到cache目录再安装
mkdir ~/.pyenv/cache
cd ~/.pyenv/cache
wget https://www.python.org/ftp/python/3.6.10/Python-3.6.10.tgz -P ~/.pyenv/cache
mv ~/.pyenv/cache/Python-3.6.10.tgz ~/.pyenv/cache/Python-3.6.10.tar.gz
cp ~/.pyenv/cache/Python-3.6.10.tar.gz /tmp

pyenv install -v 3.6.10
# 或
CFLAGS=-I/usr/include/openssl LDFLAGS=-L/usr/lib64 pyenv install -v 3.6.10

# CentOS7 下载

   $ pipenv lock --pre

   Show a graph of your installed dependencies:
   $ pipenv graph

   Check your installed dependencies for security vulnerabilities:
   $ pipenv check

   Install a local setup.py into your virtual environment/Pipfile:
   $ pipenv install -e .
