Running the script with cabal on windows seems to have some issues and is currently not fully supported.
Running the script with cabal on windows requires a cabal version greater or equal to `3.0.0.0`.
Unfortunately, it is still required to have `stack` installed so that the install-script can locate the `local-bin` directory (on Linux `~/.local/bin`) and copy the `hie` binaries to `hie-x.y.z`, which is required for the `hie-wrapper` to function as expected.
For brevity, only the `stack`-based commands are presented in the following sections.
##### Install cabal using stack
Although you can use hie for stack based projects (those which have a `stack.yaml` in the project base directory) without having cabal installed, you will need it for cabal based projects (with only a `<projectName>.cabal` file or a `cabal.project` one in the project base directory).
You can install an appropiate cabal version using stack by running:
```bash
stack ./install.hs stack-install-cabal
```
##### Install specific GHC Version
