未定义符号：PyExc_TypeError

我正在使用 Ubuntu 12.04，出现了一个奇怪的问题。我一直使用 virtualenv 命令来处理我的 Python 项目，从来没有遇到过问题。但是，由于某种原因（我真的不知道是什么原因），它现在不再起作用了。我尝试为我的一个项目创建新的虚拟环境，但它一直出现错误：

Traceback (most recent call last):

Original exception was:

您知道为什么会这样吗？如何解决？谢谢

答案1

此错误意味着 dynloader 尝试查找 PyExc_TypeError 调用条目但未找到任何条目。

如果您使用不二进制兼容的不同库，则经常会发生此错误。

你没有说你的虚拟环境在哪里。你下载了二进制文件吗？还是 dist 包？所以尝试获取正确的版本。
