Ruby on rails errors

so am new into all of this. last night I spent 5 hours reading and trying to fix the issues I have.

This worked for me. Uninstall the msgpack and then re-install it or run the following commands

gem uninstall msgpack

bundle install --redownload

Well there could be many things, as you are new and some how got issue. Let us start to diagnose issue by following few commands, see what you get. Run following commands

node -v

I have response of 12.10.0 you may have close to something, now check npm and yarn versions

npm -v

My npm is 6.11.3 and you should have something close to it. Now check yarn version

yarn --version

My system has 1.17.3 version. Now if everything installed and you got no errors but version are older try to update at close to these version.

First check what version of msgpack is installed 

gem info msgpack

It should be msgpack (1.3.1) as per your errors it has also same, also to be safe side check ruby version ruby -v it should ruby 2.6.3 version. If you are getting proper information and version of msgpack than it is fine but just do try following

gem uninstall msgpack

Now go in rails folder and run following command

bundle install

Now see if you get any error.
