我要安装的所有其他软件包都执行相同的操作.我不知道该怎么做.我已经尝试过重新安装pip，Python，我已经尝试通过conda安装软件包，但似乎无法解决问题.任何帮助将不胜感激.
It does the same for every other package I want to install. I have no idea what to do. I have already tried reinstalling pip, Python, I have tried installing the packages via conda, but I can't seem to solve the problem. Any help would be appreciated.
推荐答案
Python 3.9甚至还没有发布10天.据我所见，很多软件包还不支持Python 3.9.我认为您最好的选择是卸载Python 3.9，然后安装Python 3.8.6.如果您愿意，可以尝试以下操作以确保确定，但是我认为我无法使用.
Python 3.9 is not even released for 10 days yet. As far as i see a lot of the packages are not supporting Python 3.9 yet. I think your best bet is to uninstall Python 3.9 and install Python 3.8.6. If you want you could try the following just to make sure, but i think i won't work.
pip intstall pipwin
pipwin install <package name>
这篇关于无法安装适用于Python的新软件包(Python 3.9.0，Windows 10)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
