Problem resolved. I have successfully finished: "cargo install csvlens".

The problem as noted with EDIT-2 were lines that looked like:

token = "…"

in the config file. By commenting all places with the: xxx = "…", and running the install command, the csvlens is now installed.

 $ cargo install csvlens

Those: "…" strings look like placeholders. I think they ought to be comments if they are optional or are not always used(???). Thanks to @Kevin Reid for the suggestion.
