Why cannot I pip install a Python3 package?

Question

I am new to Python (3) using Windows 10, 64. When trying to install a package, I get the long error message pasted below. What should I do?

(base) C:\Users\xxx>pip install boilerpipe-py3

I also tried the following: pip install --upgrade pip. I got a long error message for that as well, ending with

Installing collected packages: pip
  Found existing installation: pip 19.0.1
ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'c:\\users\\xxx\\appdata\\roaming\\python\\python37\\site-packages\\pip-19.0.1.dist-info\\RECORD'

Answer 1

I think the package have a problem because I have same error when I tried

Concerning updating pip the command is this :

python -m pip install --upgrade pip

Answer 2

The package tries to download https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/boilerpipe/boilerpipe-1.2.0.0-bin.tar.gz but the server does not allow access to the file.

You should take the issue to the package maintainer.
