我无法理解这个错误：

======================================================================
ERROR: test_webtest (unittest2.loader.ModuleImportFailure)
----------------------------------------------------------------------
ImportError: Failed to import test module: test_webtest
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/unittest2/loader.py", line 260, in _find_tests
    module = self._get_module_from_name(name)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/unittest2/loader.py", line 238, in _get_module_from_name

    class TestRequest(webob.BaseRequest):

情况是：

  • 我正在尝试为我的 App Engine 应用设置处理程序单元测试。
  • 我正在关注本教程以获取单元测试框架，包括页面底部的 bash 脚本，逐字逐句。

  • 我正在使用以下命令从终端运行测试：

    ./run_tests.py /usr/local/google_appengine test/

  • 我正在使用本教程来构建我的处理程序测试。但它永远不会超过进口。我所要做的就是test/test_webtest.py生成错误：

    import webtest

  • 我已经安装了 webtest：

    $ pip install WebTest
Requirement already satisfied (use --upgrade to upgrade): WebTest in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): six in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from WebTest)
Requirement already satisfied (use --upgrade to upgrade): WebOb>=1.2 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from WebTest)
Requirement already satisfied (use --upgrade to upgrade): waitress in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from WebTest)
Requirement already satisfied (use --upgrade to upgrade): beautifulsoup4 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from WebTest)
Requirement already satisfied (use --upgrade to upgrade): distribute in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/distribute-0.6.28-py2.7.egg (from waitress->WebTest)

  • 我正在同时运行所有测试，包括通过且没有错误的旧测试。但是导入webtest其中任何一个都会在顶部生成错误。为什么？

I'm using webtest with GAE and it is working for me. I'll try to identify differences between my setup and yours to see if that helps you:

  • I'm using unittest and not unittest2.
  • I'm not using a script like your run_tests.py. I just call it from the command line like this: nosetests --with-gae

事实证明，这对于我的不同 python 环境来说是一个愚蠢的问题。

我的路径中的pipandpython链接到/user/local/bin/python. 实际上，这就是安装 webtest 的地方。

然而，我从教程中复制的代码有这个 hashbang：#!/usr/bin/python所以当我用 运行它时，它运行在没有安装webtest./run_tests.py的环境中。

运行python ./run_tests.py或更改 hashbang 以#!/user/local/bin/python解决问题。
