Had same issue on Centos 7, it can be fixed by install some packages such as libffi-devel. If it does not work maybe try install the following:
yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel xz-devel
After installing these packages, you have to reinstall the version of python. It went well in my case. Hope it helps
You will need :
sudo yum install libffi-devel
That works perfectly AlmaLinux release 8.5
Here's my one-liner (well, a 3-liner) for installing Python 3.7 on CentOS7
sudo su
yum install -y wget gcc openssl-devel bzip2-devel libffi-devel zlib-devel xz-devel ; cd /usr/src; wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz ; tar xzf Python-3.7.0.tgz ; cd Python-3.7.0 ; ./configure --enable-optimizations ; make altinstall ; rm -rf /usr/bin/python3 ; ln -s /usr/local/bin/python3.7 /usr/bin/python3 ; python3 -V
uname -a
