Note from maintainer:

Note, this only affects folks using the npm installer on Windows. If your team doesn't use Windows, or if you use Windows but install via elm-tooling or by manually downloading binaries, then you can use 0.8.6 as normal.

If you are installing via npm and using Windows, then you'll need one of the following workarounds until the next (0.8.7) release is published:

• continue using elm-format 0.8.5
• set your elm-format version to 0.8.6-windows (this version still works on any platform, but will use the fixed binaries on when Windows)

Original issue follows:

We upgraded to 0.8.6 via elm-tooling (but have also used the release asset directly), and we're getting error codes without any output whenever we try to run elm-format (or elm-format --version or elm-format --help). We're using a Windows environment.

Happy to do any troubleshooting if there's something I can do. Thanks!
