由于pycares错误，无法安装ccxt包

Question

我正在使用python 3.9.2。 我想在我创建的虚拟环境中安装ccxt包

python3 -m venv venv_cryptofolio

我遇到了一个错误，我在下面发布（但不是全部，因为它与问题描述相比太大，堆栈溢出不允许我发布）：

我尝试使用以下命令重新安装pycares：

pip install --upgrade --force-reinstall pycares

因此，我得到了一个类似的错误，如果需要，我将在这里发布

原因是什么？解决方案是什么

编辑：

我找到了删除cares文件的解决方案：

brew uninstall --ignore-dependencies c-ares
