We strongly recommend that you install Ruby gems in your home directory to avoid file permissions problems and using `sudo`.
|

You can do this with the `--user-install` option, for instance by running:
|
||||
|
||||
```sh
|
||||
gem install --user-install bundler jekyll
|

```

Or you can change the default gem path, by adding those lines to your shell config file, .e.g. `~/.bash_profile` or `~/.bashrc` if your shell is bash:
|

|

```
|

export GEM_HOME=$HOME/gems

export PATH=$HOME/gems/bin:$PATH

Jekyll requires Ruby > 2.2.5 — we recommend that you run Ruby > 2.3 though, as more and more dependencies ask for that requirement. You're good to go on macOS Mojave 10.14:
|
||||
|
||||
```sh
|
||||
sw_vers -productVersion
|
||||
10.14
|
||||
|
||||
ruby -v

||||
ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin18]
|
||||
```
|
||||
|
||||
You can install Jekyll and [Bundler](/docs/ruby-101/#bundler):
|
||||
Install [Bundler](/docs/ruby-101/#bundler) and Jekyll by running:
|
||||
|
||||
```sh
|
||||
gem install bundler jekyll
