• How did you install nvm? (e.g. install script in readme, homebrew):
  Install script in readme. Also deleted ~/.nvm and tried to reinstall. Problem persists.
• What steps did you perform?
  Can't remember, just began today. (Maybe macOS upgrade?)
• What happened?
  $NVM_DIR variable is broken, when I reset it back to $HOME/.nvm, nvm works. But it resets on every restart of terminal, although the additional junk can nowhere be found in the .bashrc or .profile file.
• What did you expect to happen?
  nvm works as usual.

Thanks in advance :-)

All that "Saving session...
...copying shared history...
...saving history...
...completed.'" output is concerning; similarly, what does which sed print out?

[te-online]

which sed outputs just normal: /usr/bin/sed

This

Saving session... ...copying shared history... ...saving history... ...completed.

seems to come from a relatively new feature of saving the bash session state.
See https://apple.stackexchange.com/questions/214862/strange-output-at-end-of-terminal-session-in-os-x-el-capitan

Remains the question: how did it get into my NVM_DIR and how do I get it out of there? 😅

https://github.com/creationix/nvm/issues/1183#issuecomment-236501456 and https://github.com/creationix/nvm/issues/1083#issuecomment-217765583 may be related; can you read through those and see if any of the suggestions apply to you?

[ljharb]

hm, https://stackoverflow.com/a/34803825/632724 also seems relevant

Okay, when I disable bash sessions, as described here https://stackoverflow.com/questions/32418438/how-can-i-disable-bash-sessions-in-os-x-el-capitan/34803825#34803825 (by creating a ~/.bash_sessions_disable file), nvm works just fine.
Getting closer... 😉

If nvm can figure out how to disable that output for individual commands, then there's a workaround I can employ.

[te-online]

I fixed it. I think the solution was more along the lines of #1183 and #1083.
There was some old nvm stuff in my ~/.profile that I didn't see before, because it was right under the rvm configuration...

I removed it and then discovered that my ~/.bashrc, where the actual nvm loading takes place, isn't even loaded to my interactive sessions, so that I now added sourcing the ~/.bashrc in my ~/.bash_profile. Now everything works as expected 🎉

Thanks for the helpful links that convinced me to check the config files once again!
