Question

刚刚在我的Windows 7盒子上安装了python，pip和virtualenv。

当我想创建虚拟环境时，请进入以下问题：

virtualenv测试给了我：

任何想法？尝试过使用注册表检查程序以及对mimetypes.py文件进行硬编码：http://www.swarley.me.uk/blog/2014/04/23/python-pip-and-windows-registry-corruption/但仍然会出现同样的错误。

Answer 1

您从read_windows_registry()功能获取的不同特定错误消息比my blog post中我所谈到的消息更多，因此我不认为删除/跳过已损坏的注册表项空字符对你有效。

我刚刚在 virtualenv 项目中找到issue #505，这似乎是在讨论您的具体问题。该线程中有几个建议 - 这些建议可以解决您的问题吗？看起来问题随后由pull request #579修复，所以也许你只需要更新到 virtualenv 的更新版本？
