I did something while trying to install the vestal_versions plug-in that ended up creating a vestal_versions directory in my app\'s root with the following:
I had the same problem and found that I had a .bundler directory in my application's root folder that was causing this. After I removed the directory, the bundle install
installed everything to the correct ruby directory again. Thanks to this post by Caleb.
bundle install <directory name>
makes the bundler install the gems in the respective directory. Running bundle install --system
will set the install directory back to the system directory rather than the custom one you provided.
I've had this problem a few times. From the root directory of your project check if you have a .bundle/config file. It should contain only:
--- {}
Delete anything else in the file and bundle install should return to installing outside of your project root.
