【中文标题】我无法安装 eventlet/gevent/greenlet【英文标题】：I can't install eventlet/gevent/greenlet 【发布时间】：2021-03-04 20:41:52 【问题描述】：我在我的一个项目中使用 Flask-SocketIO，它会导致一些问题，即客户端无法连接到服务器。我想这可能是由于它使用了flask默认开发服务器，所以我尝试安装eventlet，但没有成功。我收到了这个错误：

gevent 也会发生同样的事情。你能帮我解决这个问题吗？
仅供参考 - 操作系统：MacOS，Python：3.8.9
【问题讨论】：
我设法通过在客户端降级到 socketio 2 来解决 flask-socketio 的问题，而对于 eventlet，@Rivers 回答有效！ 【参考方案1】：这里描述了这个问题（并且有解决这个问题的方法）：https://github.com/ycm-core/YouCompleteMe/issues/3770
这里也是：https://github.com/python-greenlet/greenlet/issues/181
简而言之：
这是 macOS 上的 Python 版本的问题，尤其是 Xcode 附带的 Python 版本。
正如您在以xcrun -sdk macosx 开头的行中所见，它正在尝试构建一个arm64 切片，因此会引发错误error architecture not supported。
这些解决方案适用于其他用户：
第一个解决方案：
从 brew、python.org 或 pyenv 升级到最新版本的 Python。
第二种解决方案：
也许您已经拥有最新版本的 Python，所以您可以这样做：
brew link --overwrite python@3.8
第三种解决方案：
使用 conda：
安装 miniconda (https://docs.conda.io/projects/conda/en/latest/user-guide/install/macos.html)
# Create the environment (here, named "myenv")
conda create --name myenv
# Activate the environment
conda activate myenv
# In this environment, install the Python packages you need
conda install -c conda-forge flask-socketio
# Etc.
然后从这个虚拟环境运行你的代码
