pyenv local 3.6.3 ||env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.6.3 && pyenv local 3.6.3 #（PYTHON_CONFIGURE_OPTS="--enable-shared"加上以生成动态链接库）
pip3 install --upgrade pip setuptools wheel --index-url http://pypi.douban.com/simple –-trusted-host pypi.douban.com
pip3 install -r requirements.txt --index-url http://pypi.douban.com/simple –-trusted-host pypi.douban.com
