pip install "numpy" causing error in android chaquopy

Question

Hi I've been trying to use chaquopy to run my python script but I've been having a trouble in import part. It works fine when I run a script that doesn't require any external library and don't use install code that you would write in build.gradle.

        python{
            pip{
                install "numpy"
            }
        }

The problem comes in as soon as I slip that install code in. It comes up with the error message written below.

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

I think SSLError happened to some other people but I couldn't find what SyntaxWarning: 'str' object ~~ is about.

The problem itself wasn't in the pip install command. The real problem came from using python.exe from anaconda instead of original python.exe. I was able to solve the issue after downloading python 3.8.6 and changing buildpython path.
