【问题描述】：
在试图弄清楚如何将 Google Identity Toolkit 正确导入到我的 GAE 项目中时，我发现在 PyCharm (v. 4.5.2 pro) 中运行项目时，PYTHONPATH 不相同就像在 PyCharm 的 Python 控制台中一样。
例如，在控制台中，我从 GAE SDK (v. 1.9.23) 中正确找到了 oauth2client 库：
/usr/bin/python2.7 -u /home/usr_local/pycharm-4.5.2/helpers/pydev/pydevconsole.py 43085 43754
Python 2.7.8 (default, Sep 30 2014, 15:34:38) [GCC]
Type "copyright", "credits" or "license" for more information.

In[2]: from oauth2client import crypt
In[3]: crypt
Out[3]: <module 'oauth2client.crypt' from '/usr/local/google_appengine/lib/oauth2client/oauth2client/crypt.py'>
In[4]:
但是在运行项目时我得到：
File "/home/user/src/myapp/main/identitytoolkit/gitkitclient.py", line 47, in <module>
from oauth2client import crypt
ImportStringError: import_string() failed for 'gitkit.GitKitHandler'. Possible reasons are:
- missing __init__.py in a package;
- package or module path not included in sys.path;
- duplicated package or module name taking precedence in sys.path;
- missing module, class, function or variable;
Original exception:
ImportError: No module named oauth2client
我还在异常之前转储 sys.path（显示真实路径，/usr/local/google_appengine 是指向/home/usr_local/google_appengine_1.9.23 的符号链接）：
ERROR 2015-06-30 18:59:46,199 gitkit.py:13] ['/home/user/src/myapp/main', '/home/usr_local/google_appengine_1.9.23', '/home/usr_local/google_appengine_1.9.23', '/usr/lib64/python2.7', '/usr/lib64/python2.7/lib-dynload', '/home/usr_local/google_appengine_1.9.23/lib/webapp2-2.5.2', '/home/usr_local/google_appengine_1.9.23/lib/jinja2-2.6', '/home/usr_local/google_appengine_1.9.23/lib/pycrypto-2.6', '/home/usr_local/google_appengine_1.9.23/lib/markupsafe-0.15', '/home/usr_local/google_appengine_1.9.23/lib/setuptools-0.6c11', '/home/usr_local/google_appengine_1.9.23/lib/protorpc-1.0', '/home/usr_local/google_appengine_1.9.23/lib/webob-1.1.1', '/home/usr_local/google_appengine_1.9.23/lib/yaml-3.10']
有没有办法配置 PyCharm 将相同的 PYTHONPATH 从控制台（恕我直言）应用到开发服务器执行？
或者 - PyCharm 如何确定/配置开发服务器执行路径？ （如果需要，我什至不介意手动配置正确的路径）。
如果相关，请不要这样做，但我在处理这个项目时已经多次升级了 PyCharm 和 GAE SDK 版本。
