I'm using centos, and I installed python2.7 alternately to the default python. I'm able to install all the module I want with pip, but I can't install scipy. When I'm doing
sudo /usr/local/bin/pip2.7 install scipy
It's downloading it, but then I have this error message:

any idea how to install it?

To install Scipy on Linux: One is simply using the inbuilt package manager that comes with the installation of Linux and the second is using the pip, the python package manager. Both the methods take merely a single command to install SciPy.
With pip or Anaconda's conda, you can control the package versions for a specific project to prevent conflicts. Conda also controls non-Python packages, like MKL or HDF5. System package managers, like apt-get , install across the entire computer, often have older versions, and don't have as many available versions.
I suppose this is caused because Scipy has no Python 3.10 support (yet), so trying to install it with that Python should fail somewhere. Consider using a lower Python version, or use Anaconda (like a user suggested).
Scipy requires two Linear Algebra libraries installed on your system. Make sure the following (or variants thereof) are installed,
sudo yum install blas-devel lapack-devel
