After trying guix a few months, I came to realize that, at the a theoretical level, the environment variables are not treated as part of the dependency graph in the Guix world. Dangling environment variables happens, and can not be solved by installing everything with guix(1). I really hope that we can come up with some methods to solve these problems in a systematical way. I will keep reporting bugs caused by environment variables, hoping that it might be helpful in future development. [1]: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30093
