我有一个Python 2软件包,我正在尝试升级到Python 3.它是由一个曾经在同一个团队工作的人编写的,我现在已经不在公司了,不幸的是没有人留在团队中是有帮助的。
在对包的文件运行2to3之后,我运行python setup.py sdist
来创建包,将包放在本地存储库中,然后尝试使用pip install
来安装包。它最终错误地显示以下内容:
Exception:

该软件包的旧Python 2版本在.tgz存档中没有任何名为.dist-info
的内容,并且安装得很好。有谁知道这里发生了什么以及如何解决它?
答案 0 :(得分:0)
就我而言,这是通过删除AppData\Local\pip\Cache
文件夹(Windows)来解决的。对于其他操作系统,应该相当相似。
