When I ran the test with the rspec command, I suddenly got an error like the title, even though I was able to run it without any problems. As a result, I found out that it was due to bundle update. As a person who casually did a bundle update, I felt like "I got an error even though I didn't do anything".
Below is the result output when the rspec command is executed
$ rspec spec/models/task_spec.rb
An error occurred while loading ./spec/models/task_spec.rb.

I will write the solution first
The problem with this error is the version of the library
As it says cannot load such file --public_suffix, the library called public_suffix cannot be loaded because of the version.
In my case it was public_suffix (4.0.6) at the time of the error
Looking at the previous commit without any error, it was public_suffix (4.0.5), so change from Gemfile.lock to public_suffix (4.0.6) → public_suffix (4.0.5) Run bundle install
When I run the test with rspec again
$ rspec spec/models/task_spec.rb
An error occurred while loading ./spec/models/task_spec.rb.
Hint: Install the `did_you_mean` gem in order to provide suggestions for similarly named files.
Failure/Error: require 'rspec/rails'
LoadError:

Finished in 0.00013 seconds (files took 2.54 seconds to load)
0 examples, 0 failures, 1 error occurred outside of examples
And I got an error again, but I will fix the version of cannot load such file --minitest / assertions and minitest in the same way as public_suffix.
In my case, I changed it from minitest (5.14.2) to minitest (5.14.1)
Also bundle install and run rspec
$ rspec spec/models/task_spec.rb

Passed! Fixed: joy:
Below, I will write why this error occurred and what kind of search I tried to solve.
The essence of the problem is not Failure / Error: require File.expand_path ('../ config / environment', __dir__), but cannot load such file --public_suffix
I have a library called public_suffix, but the problem was that it wasn't loaded.
Just look at Gemfile.lock and it's installed. So is the version different? I came up with the idea and solved it
At first, I thought it was an error and searched for Failure / Error: require File.expand_path ('../ config / environment', __dir__).
Therefore, it is included in the title. However, searching did not solve the problem, I only knew that it was not a problem on the rspec side.
Even if I introduced rspec again from the initial project with rails new, the error did not disappear, so it was clear from this that it was not a problem with rspec.
After struggling for about 6 hours, I realized that Failure / Error: require File.expand_path ('../ config / environment', __dir__) was a side effect of the essential problem, so Load Error: cannot load such file- --I realized that public_suffix is the essence of the error
I didn't know that public_suffix was a library, so I thought it was an error, which is why it took a long time to resolve.
After that, I searched Gemfile.lock with public_suffix and noticed that the version was different compared to the previous commit, so I returned it and it was fixed.
By the way, searching for Failure / Error: require File.expand_path ('../ config / environment', __dir__) did not solve the problem, so I wrote this article for those who got the same error. Tata
Let's quit the innocent bundle update! The cause of the error was a change in the version of the library, so if you suddenly get an error, suspect the version. In the first place, I did not understand the behavior around bundle, and it was the worst element that I used somehow. I had a pain in the bundle so I studied in this article https://qiita.com/lasershow/items/1a048d03ddaaba98171e
Gemfile and Gemfile.lock which fixed the versions of public_suffix and minitest so that rspec works.
