我只是尝试在pypy（版本3.8）下安装包scipy==1.8.0。

pip install scipy==1.8.0

首先，scipy安装过程失败，出现以下警告和错误：

Building wheels for collected packages: scipy
  Building wheel for scipy (pyproject.toml) ... error
  error: subprocess-exited-with-error

  × Building wheel for scipy (pyproject.toml) did not run successfully.

其次，我使用以下代码安装了gfortan：

sudo apt-get install gfortran

然后scipy安装过程失败，并出现以下错误：

ERROR: Failed building wheel for scipy

我也试探着：

• 升级pip、setuptools和wheel
• 一些其他版本的scipy（1.9.0、、1.7.0、1.6.0）。

我想知道是否有解决这个问题的方法，以及Scipy是否与Pypy兼容。
