"ModuleNotFoundError: No module named 'pycodestyle'"

I have installed pycodestyle on my mac in the same path using

pip install pycodestyle

but when I check for its version I get-

    "pycodestyle" --version
Traceback (most recent call last):
  File "/Users/shashwatkhilar/tools/bin/pycodestyle", line 6, in <module>
    from pycodestyle import _main
ModuleNotFoundError: No module named 'pycodestyle'

1. Create a project directory demo
2. change directory to the project directory
3. create a virtual environment myenv
4. Activate the virtual environment.
5. Install pycodestyle

mkdir demo
cd demo
python3 -m venv myen
source myenv/bin/activate
pip install pycodestyle

Check whether it is installed or not using any of these commands

pip freeze

or

pycodestyle --version
