Flask uWSGI ImportError:没有名为reques的模块

Question

我使用的是python2.7.11:：Anaconda 2.4.0（x86_64）

我正在努力学习uWSGI。我能够得到一个“Hello World”PythonuWSGI应用程序从本教程开始：http://uwsgi-docs.readthedocs.io/en/latest/WSGIquickstart.html#the-first-wsgi-application

现在我想做一个“Hello World”Flask应用程序。当我跑步时：

uwsgi --socket 127.0.0.1:3031 --wsgi-file app.py --callable app --processes 4 --threads 2 --stats 127.0.0.1:9191

我得到这个错误：

^{pr2}$

我试过pip install -U Werkzeug，但没用。Werkzeug文档说：

“Werkzeug至少需要Python2.6才能正常工作。如果您确实需要支持旧版本，您可以下载旧版本的Werkzeug，但我们强烈建议您不要这样做。Werkzeug目前对Python3提供了实验性支持。“

我使用的是python2.7.11，因此我不确定werkzeug为什么要使用urllib.request而不是{}。在

Answer 1

你的python版本似乎有什么问题。这是来自^{}的源代码。如果您有python2.x，第一个import应该可以工作，第二个应该可以使用python3。在

try:
    from urllib2 import parse_http_list as _parse_list_header
except ImportError:  # pragma: no cover
    from urllib.request import parse_http_list as _parse_list_header

由于某些原因，您的python版本既没有python2urllib2，也没有python3urllib。在

我不熟悉PythonPython，但可能是安装已经被搞砸了吗？在
