Python RuntimeError：无法找到内置发现 python_spec='ackages.venvs/lpthw' 的解释器

Question

我正在关注“learn python 3 the hard way”中的“A Project Skeleton”，并且发生了这个错误。我仍然不知道这些实际上是什么，只是按照步骤操作。那么为什么会出现这个问题以及如何解决这个问题？

Answer 1

virtualenv 解释-packages为-pwhich 是该--python标志的缩写。你的指南中有 3 个错别字，应该是：

virtualenv --system-site-packages .venvs/lpthw

因此，只有一个具有正确 -- 符号的标志和 .venvs/lpthw 是路径，而不是标志的一部分。
