Understanding the Error Code

Error code 1, as defined in the Python documentation, signifies "Operation not permitted." Typically, this indicates that the system prohibits the action being performed.

Addressing the Installation Issue

The most probable cause of the error is the absence of setuptools. Installation of setuptools is essential for handling Python package installation and distribution. If setuptools is not already present, it can be installed by following the PyPI website's Installation Instructions.

In cases where setuptools is installed, upgrading it using "pip install --upgrade setuptools" may resolve the issue.

If the problem persists, verify the presence of the ez_setup module. If it is missing, execute "pip install ez_setup."

For further troubleshooting, attempt to install setuptools using "easy_install -U setuptools." Subsequently, rerun the "pip install unroll" command.

These measures should alleviate the installation error and allow the successful installation of "unroll."
