I am trying to build a Haskell project on `osx` but it it fails with the message [No such ghc version ‘8.8.3’](https://travis-ci.org/github/EduardSergeev/vscode-ghci-debugger/jobs/681778953). The parallel build on linux [works just fine](https://travis-ci.org/github/EduardSergeev/vscode-ghci-debugger/jobs/681778954).

Is there a _fast way_ to add GHC 8.8 on osx?  
Of course I can just use homebrew to install it but due to the recent problem with [Unknown command: bundle](https://travis-ci.community/t/macos-build-fails-because-of-homebrew-bundle-unknown-command/7296) I had to use [update: true](https://travis-ci.community/t/macos-build-fails-because-of-homebrew-bundle-unknown-command/7296/10) which makes the build [unbearably slow](https://travis-ci.org/github/EduardSergeev/vscode-ghci-debugger/jobs/681568565#L89) (~3x times slower).

Is there anything I can do add more modern than [default 7.10.3](https://travis-ci.org/github/EduardSergeev/vscode-ghci-debugger/jobs/681778953#L72) GHC to `osx` build?

UPDATE: In fact even 7.10.3 [fails on osx](https://travis-ci.org/github/EduardSergeev/vscode-ghci-debugger/jobs/681790019#L70-L74).

I don’t remember a time when we developed Haskell support with macOS in mind; the [`travis_ghc_install`](https://github.com/travis-ci/travis-build/blob/master/lib/travis/build/bash/travis_ghc_install.bash#L1) function that installs `ghc` is based on `apt`, and as such it works only on Ubuntu.
