为cffi运行setup.py bdist_wheel加密失败的构建轮

我正在尝试构建一个docker镜像。我有一个install.sh文件，它将在构建时运行。install.sh的内容如下

sudo apt-get install -y python-dev python3.5 python3.5-dev
# Install virtualenv
sudo wget https://bootstrap.pypa.io/ez_setup.py -O /tmp/ez_setup.py
sudo python3.5 /tmp/ez_setup.py
sudo easy_install-3.5 pip
pip3.5 install virtualenv
#pip install -U cffi
virtualenv -p python3.5 $HOME/venv/3.5
# Install pip packages
. $HOME/venv/3.5/bin/activate
pip install pyopenssl ndg-httpsclient pyasn1
pip install nose mock pytest coverage
CFLAGS="-O0" pip install lxml
deactivate

当pip install pyopenssl ndg-httpsclient pyasn1执行时，我收到以下错误

running install_egg_info

看完此链接后，我尝试使用更新的车轮套件

wget http://nipy.bic.berkeley.edu/scipy_installers/wheel-0.24.0-py2.py3-none-any.whl
pip install wheel-0.24.0-py2.py3-non-any.whl

还是一样的错误。尽管出现此错误，但映像已成功构建。任何帮助将不胜感激。

提前致谢。
