无法通过pip在Python 3.9上安装Pillow 7

Question

我正面临着一个我找不到解决方案的问题。我有Python 3.9.0a1和pip 20.0.2，我不能安装像Pillow这样的不同包，而对于其他包我没有这个问题，有人能帮我处理这个错误吗？这是一个与Python版本相关的问题吗？

错误：

Answer 1

正如@Njord提到的，不维护PIL。它的叉子，枕头，是。Here's information about the project.的fork还没有更新到Python3.9--因为很多包都不会更新。在此期间，您需要使用Python3.8，直到更新到来。

Pillow将在其8.0.0版本中获得Python 3.9支持。到今天为止，它是scheduled for October 15, 2020。

Answer 2

发生这种情况的原因是因为PIL还没有更新到Python 3.9，我还不知道有什么修复，但现在最好是降级到可以运行PIL的Python版本。

在这个问题上，你并不孤单。

Answer 3

我也有同样的问题。这可以通过从github克隆gym来解决。我使用GIT CMD应用程序进行克隆

    git clone https://github.com/openai/gym.git

    cd gym

    pip install -e .
