hint: See above for output from the failure.

If you get the error legacy-install-failure when trying to install a Python package using pip, you can try to fix it by following the below options.

1. If you are using Python3 make use of pip3 instead of pip and see if it works.
2. Make sure that the pip/pip3 installations is up-to-date. If not update using the below command.
   
   For pip:

   pip install --upgrade pip
   
   or
   
   python -m pip install --upgrade pip

   For pip3:

   pip3 install --upgrade pip
   
   or
   
   python3 -m pip install --upgrade pip

3. In the same way, next you update the setuptools and wheel.
   
   For pip:

   pip install --upgrade setuptools wheel

   For pip3:

   pip3 install --upgrade setuptools wheel

4. Try to create a virtual environment and then install the package within that environment, as this can help to isolate your project dependencies and avoid conflicts.
   
   Step 1: Create a virtual environment

   python3 -m venv myenv

   Step 2: Activate the virtual environment:
   
   Linux/Mac

   source myenv/bin/activate

   Windows

   .\myenv\Scripts\activate

   Step 3: Now try to install the package within the virtual environment

   pip3 install package-name
