Pipreqs unicodedecodeerror

To fix the UnicodeDecodeError when running pipreqs, you can follow these steps:

1. Make sure you have the latest version of pip installed by running the following command:

           python -m pip install --upgrade pip
         

2. If the issue still persists, you can try modifying the pipreqs source code as follows:

           1. Locate the pipreqs package in your Python installation directory. It can usually be found in "lib/site-packages/pipreqs".
           2. Open the "pipreqs.py" file with a text editor.
           3. Look for the line that reads: "requirements = requirements.decode('utf-8')".
           4. Replace it with: "requirements = requirements.decode('utf-8', 'ignore')".
         

3. Save the changes and run pipreqs again. The UnicodeDecodeError should no longer occur.

Here’s an example of the modified code:

    # pipreqs.py
    import sys
    import os

    def get_file_encoding(filepath):
        # Some code here

    def process_file(filepath):
        # Some code here

    def generate_requirements():
        # Some code here

    # Main method
    if __name__ == '__main__':
        reload(sys)
        sys.setdefaultencoding('UTF8') # Added line to set default encoding to UTF8
        path = os.path.abspath(os.path.dirname(__file__))

        args = sys.argv[1:]
        max_args = len(args)
        path_param = ''
        file_list_param = []

        # Parsing command line options
        # Some code here

        if not path_param:
            if max_args == 0:
                path_param = path
            else:
                path_param = args[0]

        generate_requirements()
