Are a environment activated?
It's best is to make new environment and not use (base) for this.
As you see here it goes over to a other version of Python that's not Anaconda.

This should of course not happen as you install to Anaconda,see the Path to Python 3.11 is different.

/Users/amirhosein/anaconda3/lib/python3.11/site-packages/pip

Example is i use Miniconda(work the same as Anaconda) and then first active a environment then it works.

G:\div_code
λ G:\miniconda3\Scripts\activate.bat tom_env

# When a environment it has (name_of_env) 
G:\div_code
(tom_env) λ pip install flask-mysqldb

Creating an environment with commands

Example for this task install new Python3.11 version with pip,can also add Spyder if need a editor.
Conda-forge for repeatable way on Windows, Linux and OSX.

conda create --name my_env -c conda-forge flask spyder python=3.11.5

Then activate environment and can install pip install flask-mysqldb.
See that when environment is activated and test pip it will point to the Python in Anaconda folder and not the OS Python version path.

G:\div_code
(tom_env) λ pip -V
pip 21.3.1 from G:\miniconda3\envs\tom_env\lib\site-packages\pip (python 3.10)
