ERROR:root:code for hash md5 was not found

Question

I'm on a Linux machine without root access. I built my own local copy of openssl and python (2.7.13). When I try to import hashlib in python, I get these error messages:

UPDATE: I just realized that the python build failed to build the hashlib module:

How should I fix this? It looks like the problem might be that it's looking for the openssl headers in /usr/include/openssl, but I'm trying to use my own installation of openssl.

Answer 1

I saw this as one of the first of a host of errors when using YouCompleteMe in vim on OSX. This was after migrating from one Mac to another using the Migration Assistant, so I wasn't doing a fresh install. In my case it was because the Anaconda python distribution was messing with Homebrew.

As brew doctor warned me, Anaconda can cause problems for Homebrew. So I removed the part of my path that included anaconda and then ran:

brew uninstall macvim
brew install macvim
brew linkapps

Homebrew complained that brew linkapps is not a good command, but it worked for me all the same, and my vim errors went away.

Answer 2

I've had a similar issue on Ubuntu 16.04. Turns out I needed the package libssl-dev.
