Some people (including but not only a core developer of Exosphere) encounter an error when following [these](https://gitlab.com/exosphere/exosphere/blob/d5440d141edd55154fcdd89e4de20cec1cdd9193/README.md#build-and-run-exosphere-as-electron-app) instructions to install Elm using npm. Here's a better problem report for the same (or very similar) issue: <https://discourse.elm-lang.org/t/error-installing-elm-by-npm/4347> We should find the best fix and update our instructions so that people can successfully build Exosphere.
