The error message indicates that the module 'fcntl' is missing. This module is used for manipulating file descriptors and is commonly used in Unix-based systems.

To resolve this issue, you can try installing the 'python3-fcntl' package using pip:

pip install python3-fcntl

If you are using a different version of Python, you may need to adjust the package name accordingly. Alternatively, you can try installing the package using your system's package manager. For example, on Ubuntu, you can run:

sudo apt-get install python3-fcntl

Once the package is installed, try running the command again
