I've just installed Jekyll 3.5.0 on Windows 10 using this instruction.
I've successfully run jekyll new my_blog and my blog folder looks like
kontiky#DESKTOP-GRQ069N:~/my_blog$ ls
404.html about.md _config.yml Gemfile Gemfile.lock index.md _posts vendor
but then I call jekyll build inside my_blog I see these warning and error messages

jekyll 3.5.0 | Error: superclass mismatch for class Mapping
Could you, please, help me avoid these warnings and errors?
I encountered the same issue and I finally decided to install Ruby on Windows without Bash On Ubuntu from this installer: https://rubyinstaller.org/downloads/
After that, I installed jekyll & bundler and, to make jekyll command-line script work, I had to execute this via bundle:
$ bundle exec jekyll serve --watch

How can we get rid of such ruby warning messages reported when I execute a Homebrew command on MacOS ?

Starting MailCatcher
~~> ERROR: Something's using port 1025. Are you already running MailCatcher?
Then when I try to use the http://localhost:1080/ shows me the app mailcatcher.
But what I need to do with the application for don't show anymore this error?
Something seems to be running on that port. It can be another instance of mailcatcher, or some other process.
On most *nix systems you can use the following command to search for a process occupying a particular port:
lsof -i :PORT
For example:
lsof -i :1025
The result will contain a PID (Process ID). You can use this to kill the offending process.
kill -9 SOME_PID
Example:
kill -9 32487

And here is what I did with the Unified installer:
I used --build-python option because I am using Enthought Canopy version of Python, which does not have the Python.h that Zope needs to in order to build its instance. So I just build up a new python -which honestly I don't know how it works, but I am guessing it is using virtualenv to isolate the installation environment, correct me if I am wrong.

Can someone explain how I can fix the issue with Pillow and get Plone installed in my machine? Thanks so much!
install like this
./install.sh --target=/home/tclap1006/all_folders/unifiedinstallers/Plone --build-python standalone
here --target is path (means at which directory u want to install ur Plone)

Jekyll runs fine though! But I guess it couldn't harm to fix this. It probably has something to do with versions of JSON not matching Jekylls dependencies?
I fixed it by updating all my gems.

Your Ruby is Ruby200-x64, which is 64-bit, so please download the 64-bit DevKit to match your Ruby.
The latest 64-bit DevKit is DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe, which can be found here, while currently yours is 32-bit DevKit-mingw64-32-4.7.2-20130224-1151-sfx.
Did you notice the difference? Yours is mingw64-32, but you need mingw64-64.
Another issue I encountered here is using Ruby2.00 which seems not an idea version.
The version worked for me is:
Ruby 1.9.3-p448
DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe
Basically it's just the version issue, other than that , just follow articles you can search around.
