python2.7 Could not find a version that satisfies the requirement pymysql

The error message you're seeing typically means that the package you're trying to install (in this case, "pymysql") either doesn't exist or is not compatible with your version of Python.

Since you're using Python 2.7, you may need to use an older version of pymysql that is compatible with Python 2.7. Try running the following command to install an older version of pymysql:

pip install pymysql==0.9.3

If that still doesn't work, you may need to upgrade to a newer version of Python that is compatible with the latest version of pymysql. Python 2.7 is no longer supported, so it's recommended that you upgrade to Python 3.x if possible.
