This post will be a little bit different cause I will add the commands that I used to get Jekyll running on my Macbook Air m1.
Trying to run Jekyll using ARM
The first thing I did was trying to install a Ruby version that is compatible with ARM and to achieve this I installed
rbenv to be able to pick a recent version easily.
$ brew install rbenv
To verify that rbenv is set up properly, I used the
type command, which displays more information about the rbenv command:
$ type rbenv
Then with the next command I init the
$ rbenv init
$ eval "$(rbenv init -)"
After running the previous command I added this
eval into my
.zshrc file. I added it using
vi command. This way I don’t have to run this command every time I open a terminal.
$ cd $ vi .zshrc
With the following commands, I installed a version that is compatible with arm64 (Apple silicon)
$ rbenv install 2.7.2
$ rbenv global 2.7.2
Running the following command we can see that the installed version of Ruby is an arm64 version.
$ ruby -v ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [arm64-darwin20]
Then after installing the Ruby version, I tried to run
bundle install into the directory that I have this blog Jekyll application, but the results were not the ones I expected.
$ arch -x86_64 bundle install Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)! To rerun under ARM use: arch -arm64 brew install ... To install under x86_64, install Homebrew into /usr/local.
Trying to run the command to start the Jekyll application locally there were some undefined symbols for the arm64 architecture.
$ bundle exec jekyll serve Undefined symbols for architecture arm64: "_ffi_call", referenced from: _ffi_raw_call in raw_api.o _ffi_java_raw_call in java_raw_api.o "_ffi_closure_trampoline_table_page", referenced from: _ffi_trampoline_table_alloc in closures.o "_ffi_prep_cif_machdep", referenced from: _ffi_prep_cif_core in prep_cif.o "_ffi_prep_cif_machdep_var", referenced from: _ffi_prep_cif_core in prep_cif.o "_ffi_prep_closure_loc", referenced from: _ffi_prep_closure in prep_cif.o _ffi_prep_raw_closure_loc in raw_api.o _ffi_prep_java_raw_closure_loc in java_raw_api.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [libffi.la] Error 1 make: *** [all-recursive] Error 1 make: *** [all] Error 2 make: ***
Also, I didn’t get lucky when trying to run the following commands.
$ arch -x86_64 bundle update arch: posix_spawnp: bundle: Bad CPU type in executable
$ arch -x86_64 bundle install arch: posix_spawnp: bundle: Bad CPU type in executable
Running Jekyll using arch x86_64
In the previous section, we have seen how I struggled to try to run Jekyll on my Apple Silicon processor. The good news is that I found a workaround, using the
arch -x86_64 before the command that downloads and executes the
homebrew installation shellscript.
$ arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
All the following commands where executed in the root folder of my jekyll project on my laptop
$ arch -x86_64 gem install --user-install bundler jekyll Successfully installed bundler-2.2.8 Parsing documentation for bundler-2.2.8 Done installing documentation for bundler after 1 seconds Successfully installed jekyll-4.2.0 Parsing documentation for jekyll-4.2.0 Installing ri documentation for jekyll-4.2.0 Done installing documentation for jekyll after 0 seconds 2 gems installed
The next step was to execute the
bundle update command:
$ bundle update Fetching gem metadata from https://rubygems.org/........... Resolving dependencies...........................

The next command to execute was
bundle install to install all of the required gems from this blog on my local laptop:
$ bundle install Using concurrent-ruby 1.1.8 Using i18n 0.9.5 Using multi_json 1.15.0 Using activesupport 220.127.116.11 Using public_suffix 3.1.1 Using addressable 2.7.0 Using bundler 2.2.8 Using coffee-script-source 1.11.1 Using execjs 2.7.0 Using coffee-script 2.4.1 ...

Use `bundle info [gemname]` to see where a bundled gem is installed.
Up and running
Now when I execute the bundle command to run Jekyll in my local I got it up and running!
$ bundle exec jekyll serve --drafts Configuration file: blog/_config.yml Source: blog Destination: blog/_site Incremental build: disabled. Enable with --incremental Generating...

In this post, we have seen the process that I followed to have running Jekyll on my Macbook Air m1. I hope that this post can help you getting it up and running faster than I did and not having to look for on the internet for responses to my problem a whole afternoon.
