React Native doesn't recognize the ruby version of rvm - ruby

I'm trying to correct the issue in my react native setup, the issue seems to be ruby.
To clarify I'm on a Mac M1
So i installed rvm, installed rvm 2.7.6 (which is the current version of ruby react native uses, information taken on their website). I did this command on Rosetta2 because it was crashing in a non-rosetta terminal : rvm install 2.7.6
The rest of the command are NOT done in Rosetta2.
Then I added rvm to the my ~/.zshrc file
export PATH="$PATH:$HOME/.rvm/gems/ruby-2.7.6/bin"
export PATH="$PATH:$HOME/.rvm/bin"
well actually, I added those two lines with the command rvm get stable --auto-dotfiles
Sometimes, I still get this error, I have to admit that I don't know why, I understood that the line above was supposed to add it to the path. Warning! PATH is not properly set up, /Users/myusername/.rvm/gems/ruby-2.7.6/bin is not at first place.
Anyway, I do this then :
rvm --default use 2.7.6
ruby --version
the last line return this : ruby 2.7.6p219 (2022-04-12 revision c9c2245c0a) [x86_64-darwin22]
which sounds okay to me, so I try to init a new project with react native : npx react-native init NewProject
Then I got something suspicious, react native telling me to download cocoapods either with gem or home-brew, but I already did it with gem. Anyway I select download with gem (or Homebrew, both result have the same error). And I got this error : Your Ruby version is 2.6.10, but your Gemfile specified 2.7.6
Re-checked the ruby version, still the 2.7.6, I'm missing something, and maybe more than just one thing but I've been on a lot of post and stuff and can't find the solution so I'm trying here.

have you tried to remove the /usr/local/bin/bundle file and then run again ?

Shopify CLI not recognising correct ruby install

When logging into a store with Shopify CLI I am given the following error:
"Your environment Ruby version, 2.6.3, is outside of the range supported by the CLI, 2.6.6..<3.2.0, and might cause incompatibility issues."
I am getting a general 'unexpected' error on a range of commands and believe it's due to the issue above. Thing is, I have latest ruby installed via homebrew, so it seems Shopify CLI is seeing another install.
I have tried reinstalling shopify-cli through homebrew using
brew reinstall shopify-cli
But this doesn't help.
If I run
ruby -v
I get the version mentioned in the error which shopify cli is seeing: "ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.arm64e-darwin21]"
Not sure if you fixed this, but I figured it out using this tool. Run brew config command, and look for the CLT: key: If it says >14.x, then you got an update from macOS v12.6 version. Please correct me if you think I might be wrong.
Just like a plus, update your Node package at least to v18.x. I hope that helps.

Installing Ruby version 2.2.4 on Windows 7

I had an old version of Ruby (1.9.3) that I am using with Selenium Webdriver.But I was getting errors while running my script.So I downloaded Ruby installer 2.2.4 version and ran it. Can someone tell me what is the command line steps to fully install it ? I tried "gem update --system" and I get the error "error fetching data". I tried "gem install ruby" and it says "successfully installed rubyzip 1.1.7"
Installing Ruby on Windows is best done by downloading the installer from the Ruby Installer site and executing the binary. There are a few things to look out for:
Make sure the correct Ruby is in your PATH. E.g.:
echo %PATH%
should include a string like C:\Ruby200\bin. The installation path may be different for your version of Ruby. If you are installing a new version, you might need to edit the path using the Windows dialog so that new sessions include it.
Also, read the instructions for installing the Ruby DevKit. You'll need it for installation of gems with native extensions.
Once Ruby is installed correctly you should be able to run ruby -v in a command window to see that the expected version is there.

gen update rake -bash: gen: command not found

I have installed Ruby, Rails, RVM, Git, and Homebrew on my Mac with OS X 10.7. I have also installed Jewelry box and have the following versions of Ruby installed: (1.9.1, 2.0.0).
I can go to a terminal window and perform a gem list command but when I try gem update rake I get the following error:
-bash: gen: command not found
I fear in all my installing, uninstalling and installing I have somehow gotten a confused environment due to possibly a conflict between a single user install and a multi-user install and do not know how to figure it out.
A whereis of Ruby and Rails show them both being in usr/bin.
There is no such command gen - try gem, it is possible you might have an alias gem=gen or function gem(){ gen "$#"; } which could make that happen

Jekyll - command not found

I am trying to get Jekyll running but I have no experience with Ruby.
As far as I can tell the installation of Jekyll has succeeded.
However:
$ jekyll
Gives an error:
-bash: jekyll: command not found
This is the gem env result:
- RUBYGEMS VERSION: 1.3.4

- EXECUTABLE DIRECTORY: /Volumes/HDD/DADU/gems/bin
- RUBYGEMS PLATFORMS:

- GEM PATHS:

And I found the following paths leading to "something" Jekyll:
~.gem/ruby/1.8/gems/jekyll-0.11.0/lib/jekyll.rb
~.gem/ruby/1.8/gems/bin/jekyll (exec file)
If you are using MacOS, from the Troubleshooting guide:
Jekyll & Mac OS X 10.11Permalink
With the introduction of System Integrity Protection, several directories that were previously writable are now considered system locations and are no longer available. Given these changes, there are a couple of simple ways to get up and running. One option is to change the location where the gem will be installed (again, using sudo only if necessary):
$ gem install -n /usr/local/bin jekyll
For others coming here with the following set up:
OS X + brewed install of ruby + (possibly) zsh
I figured the problem is that after installing jekyll as per their instructions, gem installs the jekyll gem in the brew cellar, not where the OS usually expects it (somehwere in a gem directory for ruby).
So, all that was needed here was to find out where the brew install of ruby installs gems, locate the jekyll binary, and create a symbolic link to it in /usr/bin.
Here is are the steps I took to fix it:
Type gem env and look for GEM PATHS. For me it was:
/usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1.
Make sure you can see the jekyll binary in the directory from 1 above and copy its path (if you can't, search any other paths listed in GEM PATHS for it). For me it was:
/usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/jekyll-1.4.3/bin/jekyll
Use the path from step 2 above to create a symlink to /usr/bin/jekyll. I did it by typing this (you might need sudo to create the symlink):
cd /usr/bin && ln -s /usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/jekyll-1.4.3/bin/jekyll jekyll
Now all should be merry if you type jekyll.
The easiest method of doing this is to use RVM. It manages Ruby and all its gems for you and it's easy to use. See this link for using it.
If you did not want to use that you will need to modify your PATH variables so it can find your gems. I have found this to be tedious and reverted to RVM, but here are the general steps.
You will need to find out where your gems are getting installed. If you did gem install ... the gems will be in ~/.gem/ruby/1.8/gems/bin, if you used sudo gem install ... the gems will be somewhere in /System/Library/Frameworks/Ruby.framework/Versions/1.8/Resources
You have to add this path to your PATH variable. Easiest way to do this is by running :
echo 'PATH=$PATH:above/path/to/gems' >> ~/.bash_profile
If you are using RBENV instead of RVM you simply need to run rehash in the command line after installing jekyll:
rbenv rehash
I installed my ruby2.6.0 and gem via brew on MacOS 10.14.
For me, add the following line to my ~/.zshrc solved this issue.
export PATH=/usr/local/lib/ruby/gems/2.6.0/bin:$PATH
I found jekyll executable file with command locate jekyll.
Maybe a little late, but...
I had some trouble to install Jekyll on Ubuntu and tried everything that people answered in this thread - unfortunately nothing worked.
Then, I watched a video on Jekyll's site and after installing the whole ruby package again, sudo gem install jekyll worked.
Try it before anything else:
sudo apt-get update
sudo apt-get install ruby-full
sudo gem install jekyll
jekyll -v
It seems pretty simple, but it works on Ubuntu.
One solution would be editing your ~/.bashrc file and add this line:
PATH=$PATH:~/.gem/ruby/1.8/gems/bin
This will add ~/.gem/ruby/1.8/gems/bin in Bash's lookup path.
Reopen the terminal and it should work. Or you can use the following command:
. ~/.bashrc
Following steps solved my problem
gem uninstall jekyll
sudo gem install jekyll
Open ~/.bash_profile and add this code in the last line,
export PATH=$PATH:/usr/local/lib/ruby/gems/1.9.1/gems/jekyll-2.5.2/bin
Save and close the .bash_profile
Close and reopen the mac terminal, try running jekyll now, it should work
For me, I followed this installation guide instead of their main page's installation instruction. It worked after I changed the bash_profile file and restarted Terminal.
Jekyll is a ruby gem : Ruby gems in linux, for example, are in /var/lib/gems/1.8, as can be seen in the "ruby env" output.
Thus, you need to add the executables in this directory to your path.
In general, if a ruby gem is "not found" by your OS, it simply indicates that either
1) You don't have the gem installed or
2) You don't have the gem installed in a directory that is on your path.
I have found that there have been a few issues with installing ruby and ruby gems on linux (I have found that it can be tricky on Ubuntu v10, and have confirmed this with the Ruby folks on IRC). Thus, tools like RVM or rbenv might be the best approach to setting up a stable, maintainable ruby environment.
Easier than creating a symlink just install it correctly.
If you got permission errors like a lot of people are getting when trying to use
gem install jekyll
instead use
sudo gem install jekyll
#jayunit100,
I'm running into the same issue with a Jekyll blog. I've installed the gem via RVM in a 'Blog directory and the _config.yml file says that it should generate into Blog/_site. Is it as simple as adding Blog to the PATH or is there something else I'm missing?
Update: My bad, I didn't really have the gem installed. Lesson learned: rvm requirements and brew doctor are there for a reason - before you install stuff USE THEM
In my case I had to run bundle install --force
Then bundle exec jekyll serve works, but jekyll serve still doesn't. It seems I'll have to go with the former from now on…
When you use the --user-install option, RubyGems will install the gems to a directory inside your home directory, something like ~/.gem/ruby/1.9.1. The commands provided by the gems you installed will end up in ~/.gem/ruby/1.9.1/bin. For the programs installed there to be available for you, you need to add ~/.gem/ruby/1.9.1/bin to your PATH environment variable.
For example, if you use bash you can add that directory to your PATH by adding code like this to your ~/.bashrc file:
if which ruby >/dev/null && which gem >/dev/null; then
PATH="$(ruby -r rubygems -e 'puts Gem.user_dir')/bin:$PATH"
fi
https://guides.rubygems.org/faqs/#user-install
I put it in the .bash_profile (Mac OS X).

Here's an updated answer for 2020 (soon 2021). To install any Ruby gem, whether it's Jekyll, Bundler, Rails, etc., you need a proper Ruby development environment on a Mac. There are various ways to install Ruby on a Mac, as I have written about in great detail in my definitive guide to installing Ruby gems on a Mac. The only one I recommend is to use a Ruby manager because it's the most flexible and sets you up for success for the long term. My preferred one is chruby because it's the lightest and easiest to use. As part of installing Ruby, you also need to properly configure your shell startup file (typically ~/.zshrc or ~/.bash_profile) so that it knows where to find the gems you install. Otherwise, you'll get the "command not found" error, which I've also written about.
Since there are several steps involved in setting up a working Ruby development environment on a Mac, I wrote some scripts to automate the whole process and make things easier and faster for people. You can read more about the scripts in my guide mentioned above.
I had this problem for a very stupid reason, which is that I was working on Linux and had installed both flatpak and .deb versions of Visual Studio Code. I was confused because I could successfully run bundle exec jekyll serve in the terminal application, but not from the integrated terminal in Visual Studio Code.
Well, it turns out the integrated terminal loaded my PATH correctly in the .deb version but not the flatpak one. So... if you, like me, have foolishly installed multiple versions of Visual Studio Code, check which one you are using.
This is what worked for me. I'm not developing in ruby, and don't have a lot of tools that I use it for, so I don't need RVM. I also don't need to install jekyll as root. I just want it to run.
(This answer is just a more descriptive version of answers by Santa Zhang, jayunit100, and a few others.)
1. Find Local Gem Path
> gem env
Assuming this runs, it will list a bunch of useful information. You are looking for GEM PATHS. If there are two, then you want the one that is found in your home directory. Mine was something like /home/<user>/.local/share/gem/ruby/3.0.0
If it doesn't run, install the ruby gem program and try again.
2. Find Gem Binaries Path
Look in that directory until you find the location where the jekyll executable is actually installed. I found it in /home/<user>/.local/share/gem/ruby/3.0.0/bin/jekyll. But what I need is the directory path, not the file, so: /home/<user>/.local/share/gem/ruby/3.0.0/bin/.
3. Add That to PATH
Figure out how to add a directory to your PATH environment variable. Instructions for that are too extensive to provide here, as it depends on your operating system and preferred shell, and the versions of the same. Search for that information elsewhere on Stackoverflow.
4. Restart Your Session
Close your terminal and open a new one. Make sure the directory was added to your path. Depending on how you set your PATH variable, you might need to log out of your session and log in again.

Where is the default Gem.dir path set?

This is really odd: I installed ruby 1.9.1 using a "191" suffix so that it will coexist with other versions. e.g. the executables look like ruby191, gem191 and the library directory where all of the vendor/site code lives is /usr/local/lib/ruby191. The version of RubyGems (1.3.1) that is included with ruby 1.9.1 works fine. The installation was performed with:
cd /usr/local/src/ruby-1.9.1-p429
./configure --prefix=/usr/local --program-suffix=191
make
sudo make install
However, when I upgrade my RubyGems installation with sudo gem191 update --system it appears to forget about all of the installed gems. When I checked it out with gem191 environment it is now looking in /usr/local/lib/ruby.
I know I can create a ~/.gemrc and change the location there, but that smells like a hack to me. I have spent a couple of hours trying to figure out where Gem.dir is set in the code, but have been unable to find it. Does anyone know where the default location is set?
Apparently the Gem engine didn't work properly under ruby 1.9.1, but has been fixed under ruby 1.9.2. After installing the latest build, all of my Gem issues have disappeared.
You should definitely use rvm gem for multiple ruby installations on one system.
P.S. You can view your gem installation path by using $ gem{suffix} env.
