Question

Windows 7 Professional（64位）
Python 2.7.14（2.7.14150 64 bit）
mock 2.0.0

当我从命令提示符（作为管理员）运行python -c "import mock"时，它会产生异常：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Python27\lib\site-packages\mock\__init__.py", line 2, in <module>
    import mock.mock as _mock
  File "C:\Python27\lib\site-packages\mock\mock.py", line 71, in <module>
    _v = VersionInfo('mock').semantic_version()
  File "C:\Python27\lib\site-packages\pbr\version.py", line 461, in semantic_version
    self._semantic = self._get_version_from_pkg_resources()

Answer 1

答案在最后的异常消息中：Versioning for this project requires either an sdist tarball, or access to an upstream git repository. It's also possible that there is a mismatch between the package name in setup.cfg and the argument given to pbr.version.VersionInfo. Project name mock was given, but was not able to be found.

这似乎是pbr包的问题。您是否尝试重新安装或删除它以测试是否可以解决此问题（这表明您需要在pbr上进行密集）？

Answer 2

我有同样的问题，在我的情况下更新setuptools是修复。我在这里找到了这个建议： https://github.com/testing-cabal/mock/issues/314

在更新之前，我有setuptools 0.6c11，我已经更新到最新的39.2.0。

pip install --upgrade setuptools

或实际上在我的情况下我必须在本地下载和安装，因为生产服务器没有连接到互联网：

pip download setuptools

pip install setuptools-39.2.0-py2.py3-none-any.whl

使用模拟库，python单元测试问题的异常
