cabal: /usr/bin/ar: permission denied #245

Hi, I tried to install bnfc on a MacOS 10.13 following

git clone https://github.com/BNFC/bnfc.git cd bnfc/source cabal install

upon which I get

cabal: /usr/bin/ar: permission denied

I tried to find sth about this issue. Mostly posts from 2015 saying that this issue was resolved in newer version of ghc/cabal. So I installed the latest version of the Haskell Platform for Mac OS X, which is 8.4.3.

But I have still the same problem.

Very hard to give remote advice on this.

Have you checked that the cabal that is invoked is actually the newest one? Which version is it?
Maybe you have installed some things as sudo and not files belong to root which shouldn't?! Make sure the whole trees under .ghc and .cabal belong to you and are user-writable.

I am closing this issue as it is nothing BNFC specific. Feel free to come back with more information and reopen it, if you wish further discussion.
