# it took me a lot of time to handle the python2.7 virtual envrionment issue
# memo here !
# python2.7 install on system, so I have to use sudo to operate python2.7
# download get-pip.py
# wget https://bootstrap.pypa.io/get-pip.py
# install pip for python2.7
# sudo -E bash -c "python2.7 get-pip.py"

# set PYTHONIOENCODING or LC_CTYPE
# this two system variable affect python's value of sys.stdout.encoding
# if not set this variable, sys.stdout.encoding may not be utf-8, thus print function will not work with chinese text charactor
# export PYTHONIOENCODING=utf-8
# export LC_CTYPE=en_US.UTF-8
