Setup MacOS 10.14 Mojave Discussion

Chris Oliver asked in General

Is anyone else receiving errors with MacOS 10.14 Mojave and the Mysql2 gem? I'm also getting a "Library not loaded: libssl.1.0.0.dylib (LoadError)" error when executing "rails server".

Thanks!

Hey Ted,

If you upgraded, you probably need to uninstall the gem and reinstall it so that it compiles with the new Mojave libraries.

If you have trouble installing it from scratch, see this thread: https://github.com/brianmario/mysql2/issues/1005#issuecomment-424786695

I resolved the problem with this:

gem install mysql2 -- --with-opt-lib=/usr/local/opt/openssl/lib

Yes, I have the same error.

what do you think about MacOS Mojave? Is it problematic? Have you got any other issues? I am wondering if it is better to upgrade now or to wait for a little bit.

I updated system to Mojave and generally i am happy. I had only one problem. My bluetooth didn't work in macOS Mojave. I have tried to clear the icon cache by starting your Mac in Safe Mode, then shut it down and restart it normally. It helped!

Latest version of ruby in my rbenv is 2.5.0, how can I update the list?

for readers willing to upgrade it might be a bit different. in particular if you were using rvm which is not compatible with rbenv. I could not understant why installing a new ruby version with rbenv was still linking to a previous one installed with rvm. So to sumarize: go for the installation from Chris above if you are starting from scratch...but follow this https://medium.com/@namangupta01/replacing-rvm-with-rbenv-in-os-x-9dea622bd639 if you are coming from another world ;-)

Is the header issue for Mojave resolved? When I run the command sudo installer command listed in the final steps I get the following error: installer: Error - the package path specified was invalid: '/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg'.

I haven't experienced it myself, but looks like there's some info on StackOverflow https://stackoverflow.com/questions/51270680/brew-wont-upgrade-on-mojave

Joel, I know its been a few months, but this just happened to me and I was able to figure it out. To resolve, open xcode in my case as soon as I opened it updated, even though no updates were cited in app store ...? Next, I reinstalled the command line tools in terminal with: xcode-select --install

Once completed I could run the original command without error. Hope this helps

Hi guys!
Thanks for this wonderful guide. Eveything was fine and now I have Ruby on Rails on my mac.
Sorry for stupid question: now I want to test a website. I'd like to try Spina CMS. How can I start? How can I install this gem?

Edit: maybe I made a mistake by skipping the git step... :( I do not understand the step including this instruction: cat ~/.ssh/id_rsa.pub what should I do there?

Could you elaborate about what part of this step you are having trouble understanding?

This may be of some help: https://help.github.com/en/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

I just set-up my first Rails local development environment with no problems at all !
Thank for this great tutorial Chris.

When I run "rbenv install 2.6.5", I get this errors:

clang: error: no such file or directory: '1/.rbenv/versions/2.6.5/include'
make[1]: *** [apps/app_rand.o] Error 1
make: *** [all] Error 2

How do I proceed?

Anyone getting the following error with mojave 10.14.6 when "rbenv install 2.6.5"? Getting the same error when installing any ruby version

Seems like an error when I have Anaconda installed. But even after uninstalling and completely removing Anaconda, it shows an error related to C libraries.

I get the same type of error when installing 2.7.1 on Mojave
