Pip gives error when installing vpnotebook

Vpython versions are not available from their website, but according to https://groups.google.com/forum/#!topic/vpython-users/AmIZF2v4Wkc, "pip install vpython" should work for any version of Python. I entered "pip install vpython" into the windows command prompt. After several minutes of downloading, pip gave me the following error:

  Running setup.py install for vpnotebook ... error

If your python version is greater than 2.7.9, skip to step 3

  1. Install python version > 2.7.9 [2.7.14 is the latest]

    • Download latest version of python
    • extract the archive
    • ./configure
    • make
    • make install
  2. Download and re-install pip

    • curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
    • sudo python get-pip.py
  3. Install jupyter First

    • sudo pip install jupyter
  4. Then, install vpython

    • sudo pip install vpython

The immediate fix is to install jupyter before you install vpnotebook:

pip install jupyter

Thanks for reporting this; in the future issues posted at either the location @user1114907 indicated or at the main github repo: https://github.com/BruceSherwood/vpython-jupyter/issues

This appears to be a bug in vpnotebook, upon which vpython depends. Trying to install vpnotebook in both Python 2.7 and 3.5 fails with the same error, which appears to have been caused by the package's authors not even using a basic linter. I would suggest reporting this to said authors, but there are no contact details, repositories, or project websites listed on the package's PyPI page.
