I’m trying to run `bundle exec jekyll serve` in Terminal and when I do, I receive this.

```
Could not find gem 'autoprefixer-rails' in any of the gem sources listed in your Gemfile.

Run `bundle install` to install missing gems.

```

So I run `gem install autoprefixer-rails`

and I get

```
Successfully installed autoprefixer-rails-9.7.4

Parsing documentation for autoprefixer-rails-9.7.4

Done installing documentation for autoprefixer-rails after 0 seconds

1 gem installed

```

and I run `bundle exec jekyll serve` again, and I run into the same message as before.

Help anyone?

The message is asking you to run `bundle install` not `gem install ...`

Here’s a screenshot. Might be more useful.

Interesting. Bundler is not able to install fresh native extensions.  
What is the output when you run `bundle config path`?

**Edit:** Nevermid that. I think the problem is that your directory path contains a space:  
`/Google Drive/`. Try renaming the directory to `GoogleDrive` or `Google_Drive`…

Then rename `003 Faculty` to something without the space…

Yes, that’s because `003 Faculty` has a space too…

Did you try renaming `003 Faculty` to something without the space…?

Yeah, that seemed to work. Weird… It was never an issue before? Does it have something to do with the new MacOs update?

So I ran `bundle exec jekyll serve` and it seems to be running now, minus all the errors appearing.

Can’t say for certain if its the macOS update. It was always noted that installing native extensions in a path containing spaces can lead to bugs… 🤷‍♂️

Regarding the current load of warnings you see…, it is explicitly because of Ruby 2.7.0.  
They will go way when Jekyll releases v4.1… Until then you can edit your Gemfile to point to the Jekyll GitHub repository if you want…

How can I edit my Gemfile to do that?

Sorry for all the questions. Jekyll has always run so smoothly.

Edit your Gemfile so that it looks like the following:

```ruby
gem 'jekyll', github: 'jekyll/jekyll'

```

Alright so I did that and ran

```

  In Gemfile:
    html-proofer was resolved to 3.15.1, which depends on
      mercenary (~> 0.3)

    jekyll-sitemap was resolved to 1.4.0, which depends on

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

```

so I ran `bundle update`, which worked successfully and now when I run `bundle exec jekyll serve` again, I receive this:

Frustrating isn’t it?  
You were probably using `jekyll-assets` before. But removed it for some reason… (😈)

The other thing is `jekyll-assets` has not released a Jekyll 4.0 compatible version yet. I’m not totally familiar with that project though so can’t really recommend that you try pointing your Gemfile to the plugin’s GitHub repository…

Super super frustrating.

I added `jekyll-assets` back in because a _certain someone_!! told me to remove it.

Still running into the same issue. Here’s my repository: [https://github.com/christiantype/Faculty-One](https://github.com/christiantype/Faculty-One)

So is there just nothing I can do?

If your site builds fine with Jekyll 3.8, use that instead of the jekyll `master`.  
Yes, you’ll have those warnings. You can search the internet for tips to turn them off…

Last question. How do I use that instead of jekyll master?

If that doesn’t work. I think I’m just going to start my website from scratch.
