无法在mac上安装python arcade

Question

我想用python做点什么，所以我试着安装arcade。只是pip install arcade不起作用，我也尝试了其他的东西，比如关注this链接。这些都不起作用，它总是给我同样的错误。这是整个日志。

它找不到setup.py，到目前为止，我搜索到的东西都没有帮助到我。因此，如果你们中的任何人能帮助我解决这个问题，那就太好了。

您必须在系统上安装库GEOS。运行此命令- brew install geos。

如果您没有brew，可以从以下位置下载：https://brew.sh

在ubuntu上，你可以做$ sudo apt-get install libgeos-dev。
