Environment information

• py-solc-x Version: 3.2.0
• solc Version: 0.4.18
• Python Version: 2.7.16
• OS: osx

What was wrong?

when running the install file for solc 0.4.18:

brew install https://github.com/ethereum/homebrew-ethereum/blob/2aea171d7d6901b97d5f1f71bd07dd88ed5dfb42/solidity.rb

I get this:

Unfortunately I'm not using OSX myself and I'm not familiar with Ruby, so I can't be of much help :(

There is a push to serve precompiled solc binaries for OSX - ethereum/solidity#3168 As soon as that happens I'll convert this package to use them, and this problem should become a thing of the past. In the meantime, I'm really sorry but there's not much I can offer. Possibly someone in the solidity gitter will know how to solve it.

@ilanDoron I think that you're just using the wrong URL. The one you posted is a HTML page that includes the whole Github UI. You cannot execute that as Ruby code - that's why you get errors about "unexpected '<'". You need to use a direct link to the raw Ruby file:

@cameel good catch! I've updated the wiki to better emphasize this.

Closing this for now, @ilanDoron if you have further issues feel free to re-open or ping me on gitter.
