hey everyone! 😄 I want to know if someone can help me. I've just started using Pants, and I'm now creating my Docker image to publish the application. I have the setup working locally to build my PEX file, but when I install 
pants
on my Docker image and I run 
pants package
I get this error:

sorry, I was able to figure it out. It turns out it was happening because I was running 
pants
the first time on the folder that contained all my files. Honestly, I don't think that should happen, but if I run it on another folder before it solves the issue
c
That seems like it could be due to a permission issue on some file or folder perhaps.
b
@curved-television-6568 I'm not sure, simply by running 
pants
before copying the contents to the Docker image solved the issue
