我遇到了一个找不到解决方案的问题.我有 Python 3.9.0a1 和 pip 20.0.2，我不能安装不同的包，比如 Pillow 而其他包我没有这个问题，有人可以帮我管理这个错误吗?是不是Python版本的问题?

I'm facing an issue that I can't find a solution for it. I have Python 3.9.0a1 and pip 20.0.2 and I can't install different packages like Pillow while with other packages I don't have this issue, someone can help me to manage this error? Is it an issue related to the version of Python?

错误:

推荐答案

正如@Njord 提到的，PIL 没有维护.它的叉子 Pillow 是.这里是有关该项目的信息. fork 尚未针对 Python 3.9 进行更新 - 因为许多软件包不会更新.在此期间，您需要使用 Python 3.8，直到更新到来.

As @Njord mentioned, PIL is not maintained. Its fork, Pillow, is. Here's information about the project. The fork is not yet updated for Python 3.9 - as many packages will not be. You'll need to use Python 3.8 in the meantime until the update comes.

Pillow 将在其 8.0.0 版本中获得 Python 3.9 支持.截至今天，计划于 2020 年 10 月 15 日.

Pillow will get Python 3.9 support in its 8.0.0 release. As of today, it's scheduled for October 15, 2020.
