Hi,
I am attempting to setup a development enviroment for Discourse.
When running `bundle install` based on the instructions at [Install Discourse on macOS for development](https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-macos-for-development/15772) I get an error.
```plaintext
An error occurred while installing cppjieba_rb (0.3.0), and Bundler
cannot continue.
Make sure that `gem install cppjieba_rb -v '0.3.0' --source
'https://rubygems.org/'` succeeds before bundling.
```
I follow the suggestion and get the following output
```plaintext
$ gem install cppjieba_rb -v '0.3.0' --source
ERROR: While executing gem ... (OptionParser::MissingArgument)
missing argument: --source
```
What am I doing wrong and how can I fix the issue?

Can you try the docker based dev env, it is way simpler

I just checked my system and realized some dependencies and the ruby version manager thing needed to be configured . That might be while bundler is installing.
That said Docker does sound simpler, I intend to submit pull requests to Discourse, is the Docker environment still right for me? If so could you link me to information on it? Thanks ❤

Yes it is perfect for that, search for docker development environment, there is a howto

The only thing I could find was [(Superseded) Set up Docker in Virtualbox for 'production' testing](https://meta.discourse.org/t/setting-up-docker-in-virtualbox-for-production-testing/12111) which looks terribly outdated considering it’s use of Ubuntu 13. Could you link me to exactly the thread you’re talking about?

Thanks, and turns out - since I tried to install while on system Ruby rather than the correct version, future bundle installs were trying to use system rather than correct bundler. Deleting discourse and recloning solved the issue.

Vagrant is not a supported dev environment, please follow one of the supported **Developer Environment** guides:

I can’t seem to get the environment to set up correctly due to this `cppjieba_rb` library
Tried to fix by: `sudo gem install cppjieba_rb -v '0.3.3' --source 'https://rubygems.org/'`
Here was it’s output:

Ok, so you ran the script, cloned the repo, and it’s falling over during the `bundle install`?

An error occurred while installing cppjieba_rb (0.3.3), and Bundler cannot continue.
Make sure that `gem install cppjieba_rb -v '0.3.3' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
cppjieba_rb
```
FYI: Xcode version info:
The Google God has yielded no solutions or fruit. There was [tangential GitHub issue](https://github.com/wurmlab/sequenceserver/issues/403) which suggested:
> Try running `gem install rake` and then running `bundler` again. If that doesn’t work, there are a few other solutions listed in the above post.
.. however, this yielded nor any fruit and the error remains even if I start the cloning process from scratch again.

**Update:**
This problem appears to be resolved by a related **TLDR: don’t use the ruby comes with mac.**
See: **[xavi-](https://github.com/xavi-)** commented [on May 16, 2019](https://github.com/airbnb/sparsam/issues/17#issuecomment-492884502)
I followed his (xavi’s) instructions, switched to `rbenv` and `bundle install` worked, but still needs confirmation …
**Update 2:**
**Confirmed:** Switching to `rbenv` and setting up the current `PATH` environment `~/.rbenv/shims` works and resolved this issue.
```plaintext
export PATH=~/.rbenv/shims:$PATH
```

I was stuck on this Error and what you suggested (setting rbenv in PATH) worked for me,
thanks a lot.
