To install on Linux:
Unzip the google_appengine_1.9.69.zip file that you downloaded, for example:
unzip google_appengine_1.9.69.zip
There is no App Engine installation script that you need to run after unzipping the files.
Add the google_appengine_1.9.69 directory to your PATH:
export PATH=$PATH:DIRECTORY_PATH/google_appengine_1.9.69/
Make sure Python 2.7 is installed on your machine using the following command:
/usr/bin/env python -V
The output should look like this: Python 2.7.[NUMBER]. If Python 2.7 isn't installed, install it now using the installation instructions for your Linux distribution.
解压：
unzip google_appengine_1.9.69.zip
加入到环境变量里 /etc/profile
sudo vim /etc/profile
写入：
export PATH=$PATH:home/hades/google_appengine_1.9.69
完成！
