开发环境

pyenv

1. 使用github仓库代码安装pyenv

mkdir ~/.pyenv
git clone https://github.com/pyenv/pyenv.git ~/.pyenv
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile
source ~/.bash_profile

Fish shell note: 添加到 ~/.config/fish/config.fish

status --is-interactive; and source (pyenv init -|psub)

2. 使用离线包安装python
   NOTE：国内下载很慢，建议使用 搜狐镜像 下载到本地进行安装

mkdir ~/.pyenv/cache
wget http://mirrors.sohu.com/python/$version/Python-$version.tar.xz -P ~/.pyenv/cache

3. 安装你需要的 Python 版本

pyenv install $version

4.切换 Python 版本

pyenv local $version

pyenv-virtualenv

1. 安装

git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
source ~/.bash_profile

Fish shell note: 添加到 ~/.config/fish/config.fish

status --is-interactive; and source (pyenv virtualenv-init -|psub)

2. 切换 virtualenv

pyenv virtualenv 3.6.3 venv36

pyenv virtualenvs
3.6.3/envs/venv36 (created from /home/username/.pyenv/versions/3.6.3)
* venv36 (created from /home/username/.pyenv/versions/3.6.3)

3.激活 virtualenv

pyenv activate <name>
pyenv deactivate
