your ruby version is 2.7.0, but your gemfile specified 2.7.1

Explanation for each step:

Step 1: Check Ruby version To verify the Ruby version installed on your system, you can use the following command in your terminal:

ruby -v

This will display the version of Ruby currently installed.

Step 2: Check Gemfile The Gemfile is a file in your Ruby project that specifies the dependencies (gems) required by your application. Open the Gemfile in a text editor and look for the line that specifies the Ruby version. It should look something like this:

ruby '2.7.1'

This line indicates that your application requires Ruby version 2.7.1.

Step 3: Compare versions Compare the Ruby version installed on your system (from step 1) with the version specified in your Gemfile (from step 2). In this case, the installed version is 2.7.0 and the Gemfile specifies version 2.7.1.

Step 4: Resolve the inconsistency To resolve the inconsistency between the installed Ruby version and the version specified in the Gemfile, you have a few options:

Option 1: Update Ruby If you have administrative privileges on your system, you can update your Ruby installation to the required version (2.7.1 in this case). You can do this by following the installation instructions for your operating system, or by using a version manager like RVM or rbenv.

Option 2: Modify Gemfile If updating Ruby is not feasible or desirable, you can modify your Gemfile to specify the Ruby version that is installed on your system. In this case, you would change the line in your Gemfile to:

ruby '2.7.0'

Save the modified Gemfile and run the following command in your project directory to update the dependencies:

bundle install

Step 5: Verify the change After resolving the inconsistency, you can verify that the correct Ruby version is being used by running the following command in your project directory:

ruby -v

This should now display the updated version (2.7.0 in this case).

Step 6: Run your application With the correct Ruby version specified in the Gemfile and installed on your system, you should now be able to run your application without any version conflicts.

That's it! Following these steps should help you resolve the inconsistency between your Ruby version and the version specified in your Gemfile.
