How to make virtualenv accessible in the flask applications with gunicorn guide?

Heya,

Just came across this answer and decided to write some general guidelines for anyone who comes across this in the future despite the old question.

This problem could be due to lack of permission in your current directory.

Here are a few things you can do to resolve this:

1. First, check if you have enough permission in your current directory by running the command ls -l. If the user and group are not your’s, then you should change the directory to somewhere you have full access to.
2. Create the virtual environment in a directory where you have full access. If you’re not sure, you can always create it in your home directory.
3. Also, make sure that you have the correct and updated version of virtualenv. Depending on your system, you can update it with pip install --upgrade virtualenv.

Remember, it’s always best to avoid using sudo when it’s not necessary as it can lead to permission issues like what you’re experiencing now.

For further details, you can visit the Python setup on CentOS guide on DigitalOcean’s community tutorials.

Hope that this helps!
