bundle install returns "Could not locate Gemfile"

Question

You just need to change directories to your app, THEN run bundle install :)

You may also indicate the path to the gemfile in the same command e.g.

BUNDLE_GEMFILE="MyProject/Gemfile.ios" bundle install

I had this problem as well on an OSX machine. I discovered that rails was not installed... which surprised me as I thought OSX always came with Rails. To install rails

• sudo gem install rails
• to install jekyll I also needed sudo
• sudo gem install jekyll bundler
• cd ~/Sites
• jekyll new <foldername>
• cd <foldername> OR cd !$ (that is magic ;)
• bundle install
• bundle exec jekyll serve
• Then in your browser just go to http://127.0.0.1:4000/ and it really should be running

You must be in the same directory of Gemfile

When I had similar problem gem update --system helped me. Run this before bundle install

I had this problem on Ubuntu 18.04. I updated the gem

sudo gem install rails
sudo gem install jekyll
sudo gem install jekyll bundler
cd ~/desiredFolder
jekyll new <foldername>
cd <foldername> OR 
bundle init
bundle install
bundle add jekyll
bundle exec jekyll serve

All worked and goto your browser just go to http://127.0.0.1:4000/ and it really should be running

1. Make sure that the file name is Capitalized Gemfile instead of gemfile.
2. Make sure you're in the same directory as the Gemfile.
