Good Morning,

When attempting to install Python packages using "pip install ", I get the following error:

pip install error 1

The solution posted here works for most packages. Unfortunately, packages like usaddress, which download additional data during the installation process will result in the following error if the whl/tar is installed locally:

pip install error 2

I believe this is due to a firewall issue, so the solution here did not apply in this case, but may be helpful to others.

Any advice would be greatly appreciated.

*edit: I should have also mentioned that I updated my pip version this morning, after the installation failed.

Python version:

Python 3.6.4 | Anaconda, Inc. | (default, Jan 16 2018, 10:22:32) [MSC v.1900 64 bit (AMD64)] on win32

  • Which version of Python are you working on? – MAYANK SHARMA Apr 20 '18 at 15:39

  • Try upgrading pip and then use "pip install usaddress". If still, it doesn't work, then my suggestion would be to check it installing on Anaconda Python 3.5.2 version because I also faced some issues on installation in Python 3.6.4, so I downgraded Python and Python 3.5.2 is working well & In fact, usaddress was also installed perfectly in it. – MAYANK SHARMA Apr 20 '18 at 16:12
  • Thank you for the recommendation. In addition to verifying an up-to-date pip, I tried installing the usaddress whl on Python 3.5.2, but was getting the same error message as before. – Keith Lyons Apr 20 '18 at 16:45

I found a solution. The issued turned out to be that although I downloaded and tried to pip install usaddress, that particular library had a few dependencies that also needed to be installed.

In the "pip install error 2" example from my question, where I tried to install a local copy of usaddress downloaded from pypi.org, you can see a red sentence at the bottom of the screenshot which says, "Could not find a version that satisfies the requirement future>=0.14". It means that I need to also install a package called "future", of version greater than or equal to 0.14. I went on to pypi.org, and was able to download and pip install the future package.

I found that some libraries have many dependencies, so it can take a few minutes to keep downloading and installing dependencies, but it was an effective way to get around the firewall.

I hope this saves somebody else some time!
