Fix Your Ruby version is 2.6.8, but your gemfile specified 2.5.5-CodePudding

On my local machine I'm using rbenv

When I run bundle install I get:

The git source `git://github.com/sinatra/sinatra.git` uses the `git` protocol, which transmits data without encryption. Disable this warning with `bundle config git.allow_insecure true`, or switch to the `https` protocol to keep your data secure.
Warning: the running version of Bundler (1.17.2) is older than the version that created the lockfile (1.17.3). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

Your Ruby version is 2.6.8, but your Gemfile specified 2.5.5

The problem is, when I run rbenv versions, I get the right version (2.5.5):

  system
* 2.5.5 (set by /Users/Mahmoud/dev-reps/non-docker/normal/.ruby-version)

And when I run which ruby, it correctly points to rbenv:

/Users/Mahmoud/.rbenv/shims/ruby

Even ruby -v gives the correct version:

ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-darwin21]

So persumably, 2.5.5 is the ONLY version I have. In addition to this I tried all the usual hacks related to bundler:

bundle uninstall, gem uninstall bundler -v 1.17.2 but nothing seems to work.

Another "interesting" fact that I think gives a hint: which bundle gives:

/usr/local/bin/bundle

My question is where is this 2.6.8 coming from? And how can I fix this and start the server?

CodePudding user response：

Finally got it working.

So the key to the problem as well to the solution was the fact that which bundle gave:

/usr/local/bin/bundle

while which ruby gave:

/Users/Mahmoud/.rbenv/shims/ruby

indicating that bundle isn't using ruby from rbenv.

I already had the path set in ~/.bash_profile:

export PATH="$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"

but apparently this was not enough as I was using zsh. Had to add those same 2 lines to ~/.zshrc as well and restarted terminal. Now bundle install is working as expected.

After updating ~/.zshrc which bundle gives:

/Users/Mahmoud/.rbenv/shims/bundle

indicating that the problem was just that bundle was using the wrong ruby.

So if you have this problem, just make sure ~/.bash_profile and ~/.zshrc have the correct path by adding the 2 lines indicated above. Restart terminal and check if its working now.
