布朗尼不工作：Cython 未定义符号 _PyGen_Send

Question

我在 Fedora 35 上设置了我的开发环境，当我运行任何布朗尼命令时，例如$ brownie console甚至brownie --version我收到以下错误：

Traceback (most recent call last):

设置：
Python=3.10.1
Cython=0.29.26
gcc/gcc-c=11.2.1-7.fc35.x86_64
Ganache CLI=v6.12.2

$ pipx list

venvs are in /home/philippbunke/.local/pipx/venvs
apps are exposed on your $PATH at /home/philippbunke/.local/bin
   package eth-brownie 1.16.4, Python 3.10.1
    - brownie

$ $PATH

/home/philippbunke/.local/bin:/home/philippbunke/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/var/lib/snapd/snap/bin

我花了一整天的时间试图修复这个错误，请帮助我！

这里的问题似乎是Python 3.10.1！

我使用 anaconda 使用 Python 3.8.12 创建了一个新的虚拟环境，使用安装了布朗尼，pipx install --python python3.8 eth-brownie它成功了！

这里的技巧是，还告诉 pipx 使用另一个 python 版本，否则它将创建对全局 python 版本的依赖，在我的例子中是 python 3.10。
