I only have one alex installed under ~/.cabal/bin. It seems working with shell environment, but not cabal.
My guess: You added ~/.cabal/bin to the path, but have quoted the path, like export PATH="~/.cabal/bin:$PATH" in your .bashrc That does not work. Tilde expansion is *not* done for quoted strings, so cabal looks (among other places) for "~/.cabal/bin/alex". Now, there is no directory "~" in your file system, so alex is not found. Check: $ printenv PATH If the output contains ~, it won't work. If it doesn't, well then something else must be broken. Fixes 1) don't quote the path, export PATH=~/.cabal/bin:$PATH works. 2) (better) Use $HOME instead of ~ (works quoted or unquoted) 3) write out your home directory completely
