The closest alternative is to use “ bundle install -deployment”, which installs any gems in the “ vendor/bundle/” directory within that one application. Setting a GEM_HOME value will also installs the gems to a directory within your home directory, however there is no way to tell “ bundle install” to use “ gem install -user-install” when it needs to install gems. The alternative is to use things like the “ gem install -user-install” option when installing gems, which installs the gems to a directory within your home directory. In my case, I always set this variable when using Ruby from Homebrew, even though I’m normally the same user that installed Homebrew and Ruby (and therefore have write permissions to the directory). This is normally done if you don’t have write access to the normal system-wide Ruby gems directory (maybe because you’re using a system’s “native” Ruby and you’re running as a user without administrator rights), or if you don’t want to risk making system-wide changes (which is always a good excuse.) Setting a value for the GEM_HOME variable will override the location where “system-wide” Ruby gems will be installed. If you updated your PATH, be sure to start a new shell and make sure the change worked. For example, if “ ruby -v” says “ 2.7.2p137”, the directory name will still be “ 2.7.0”. Note that the directory name will always be “ n.n.0”, regardless of the “point release” version. $PREFIX/lib/ruby/gems/3.0.0/bin - if using Ruby 3.0.x.$PREFIX/lib/ruby/gems/2.7.0/bin - if using Ruby 2.7.x.For executables installed as system-wide Ruby gems when GEM_HOME is not set (see below).Make sure the following directories are in your PATH, in the appropriate order. In theory Jekyll should work with the Ruby 2.6 that comes with macOS 11, however I couldn’t get it to work when I tried on an Intel machine /opt/homebrew/bin - contains the brew command itself, along with symlinks to executables installed by Homebrew packages.I generally want binaries installed by Homebrew to be used instead of binaries with the same names that came with macOS, so I have it in my PATH before the /usr/bin and /bin directories. Make sure the following directory is in your PATH, in the appropriate order. Check PATHįor arm64 systems, Homebrew installs everything under /opt/homebrew/ and does not symlink installed binaries into /usr/local/bin/ like it does on Intel systems.
It’s entirely possible that they may have updated something and I haven’t updated this page yet. Note: if you’re going to copy/paste this, please copy/paste from the Homebrew web site instead.
