python - Python RuntimeError : failed to find interpreter for Builtin discover of python_spec ='ackages.venvs/lpthw'

Question

我正在从“以困难的方式学习python 3”中的“项目骨架”中出现此错误。我仍然不知道这些到底是什么，只是按照以下步骤操作。那么为什么这个问题以及如何解决呢？

virtualenv将-packages解释为-p，它是--python标志的缩写。
您的指南中有3种错别字，应该是:

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

因此，只有一个带有正确符号(.notvs和.venvs/lpthw)的标志才是路径，而不是标志的一部分。
