I'm getting this error after installing ruby 3.0.2 and running bundle exec rake test, it seems a tempfile is not being found:

A colleague and I had this same issue using ruby 3.0.2 installed via rbenv.

I switched to using chruby and installing 3.0.2 using ruby-install and now, I no longer have this issue; I'm able to run the tests successfully.

I'm not sure if there's a more straightforward solution. I haven't dug into the specifics of why this works yet (I've only ever used rbenv and RVM before), but I saw @tenderlove's setup during this online event and I attempted to more closely replicate his by switching installation/version management tools.

Thanks @Thomascountz for your hints, I investigated a bit more and I saw that rbenv passes the following flags when compiling ruby (see https://github.com/rbenv/ruby-build/blob/e3909413561b85c80ddc3bb05949a38d8ec65114/share/ruby-build/3.0.2#L2). I guess ruby-install uses different flags or paths. I tried to install ruby with rbenv changing some of the flags but I was not able to make it work anyway.

I experience the same error with ruby 3.0.2 installed via rbenv/ruby-build.

I was able to make it work with by installing ruby 3.1.0-dev with rbenv/ruby-build and using that version.
