No such file or directory when getting assets

[xTachyon]

My web dev experience is almost 0, so this might be something trivial, but:

When running cargo xtask assets --watch, as mentioned in DEVELOPMENT.md, I get the following error:

    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.11s
     Running `target/debug/xtask assets --watch`
Lockfile is up to date, resolution step is skipped
Already up to date
Done in 768ms
Error: Could not watch the asset directory

Caused by this error:
  1: No such file or directory (os error 2) about ["/home/../margo/ui/dist"]
