Does anyone install programming language environments from the fedora mirrors? Every time I've tried and start getting anywhere with a new language it inevitably leads to a hell of PATH variable amputation.
RVM , rvm gemsets, rvm use system, etc VS ruby rpm
'rvm use system' thinks there's a system ruby, my GEM_PATH is completely schizophrenic, bundler thinks it is compiling code from space, its a total mess
More recently I experienced the joys of the packaged GHC and Cabal RPMs and had to take a vacation to recover from that hell.
Now once more I'm hit with:
Compiler version mismatched, found ghc-7.8.4 ... expected ghc-7.10.2. TT
Try running "stack setup" to install the correct GHC into /home/gustav/.stack/programs/x86_64-linux/
Oh. No. I feel another RVM approaching. I just hope Cabal is completely off my laptop, any leftover config files are sure to cause madness.
Every time I start working on a new language (or go back to an old one, in the case of ruby) I appreciate the "copy the source into your own repo"-style of vendoring followed by golang more and more.
