What is the cause of "Permission denied: 'curl-config'" error when trying to create building airflow in docker-compose using pycurl in requirements?

edit

The "Permission denied: 'curl-config'" error occurs when the user does not have sufficient permissions to access or execute the "curl-config" file. This file is used by pycurl to build and install the library in the virtual environment.

To fix this error, you can try running the docker-compose command as a root user. Alternatively, you can provide the necessary permissions to the file by using the chmod command:

sudo chmod +x /usr/bin/curl-config

This will give execute permissions to the curl-config file and allow the pycurl library to install properly.
