python - 没有名为 Flask (GAE) 的模块

Question

我正在尝试在这里运行普通的 gae-init 项目 https://github.com/gae-init/gae-init/开始使用 Flask 和 GAE。我不断收到此错误 -

INFO     2015-10-11 13:28:25,924 devappserver2.py:763] Skipping SDK update check.
INFO     2015-10-11 13:28:26,001 api_server.py:205] Starting API server at: http://localhost:48281

INFO     2015-10-11 13:28:28,560 module.py:786] default: "GET /_ah/warmup HTTP/1.1" 500 749

我尝试添加 PYTHONPATH到我的 .bashrc 文件 export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages (dist-packages，因为 pip 似乎是在其中安装我所有的东西？我看到提到了 site-packages ，但该文件夹中没有任何内容)

我尝试过运行 pip install -r requirements.txt -t lib因为据我所知，dev_server.py根本找不到flask。

我已经查看了答案 here和 here但他们并没有多大帮助。第二个似乎很有希望，但我运行的是 Ubuntu 而不是 Windows。

我是 Python 的初学者，所以我在学习的过程中试图弄清楚这一点。

感谢您的帮助!

您必须通过将 appengine_config.py 添加到项目根目录来告诉您的应用第三方库的位置。
