Build Failures: capybara -- `require': cannot load such file -- nokogiri (LoadError)

[huangsam]

I'm not sure how to resolve this one. I've been trying to update my Gemfile to use different versions of capybara and so far nothing has been working to resolve this issue for my Travis-CI builds. Any ideas?

[roidrage]

Does the Gemfile also include nokogiri? Or is nokogiri installed as part of the bundle install?

[sarahhodne]

Could you please link us to the build where you are seeing this?

It looks like nokogiri is not being installed, which is odd since it's a dependency of Capybara. I wonder if the bundle install output will give any clues.

[huangsam]

Gemfile does not include it, but Gemfile.lock does include it

[roidrage]

That's quite odd, the bundle install doesn't seem to install nokogiri?

[huangsam]

Not from what I see on the build. Rather curious.

[huangsam]

I've seen some related issues here and there. Not sure if that helps with your troubleshooting.

[roidrage]

Could you add nokogiri directly to your Gemfile and see if that helps?

[huangsam]

I did what you suggested, and the build still failed.

[huangsam]

I even did a before_install: gem install nokogiri. According to Travis CI, nokogiri installed but the build still fails.

[BanzaiMan]

Very curious. I don't see nokogiri getting installed. Did I miss it?

[huangsam]

See it now?

Perhaps dependency resolution is failing somehow.

[huangsam]

Yeah. That's exactly why I did the before_install, as a workaround. Clearly, injecting nokogiri into the Gemfile and before_install approach did not work.

[BanzaiMan]

Truths experiment: create a small project locally with just nokogiri in Gemfile and see if installs nokogiri and its dependencies. If it works, try building it on Travis. We'll understand where the problem is.

[BanzaiMan]

BYW if bundler does not activate nokogiri, installing it beforehand doesn't do any good.

[BanzaiMan]

Try this experiment...

[huangsam]

Did what you wanted - super-trivial and it breaks. Just got the error.

[BanzaiMan]

I see the problem now. You are bundling the Windows version of nokogiri in your Gemfile.lock (https://github.com/huangsam/travis-nokogiri/blob/master/Gemfile.lock#L5), so that bundle install on our Linux VM tries to rebundle, but it fails.

See http://stackoverflow.com/questions/3642085/make-bundler-use-different-gems-for-different-platforms for a possible workaround.

[huangsam]

One thing I did one want to mention is that when I do the approach of hiding the Gemfile.lock using a .gitignore on my Windows machine, Travis-CI works. However, when pushing to Heroku I get this nasty request:

It's like StackOverflow is telling Windows users one thing, while Heroku is telling them another thing.

[BanzaiMan]

Not owning a Windows machine, I don't know what the best practice is. However, you can try creating a second Gemfile, identical to ./Gemfile, and point to it with gemfile in ./travis.yml.

[huangsam]

Bingo! Works on Heroku and Travis CI now. Thanks a bunch!

I'm using ruby 2.3.3 on my project and nokogiri 1.6.8.rc2.The build failed on Gitlab ci.The error message is: `require': cannot load such file -- nokogiri (LoadError).
could someone helps?Thanks!

[BanzaiMan]

@hypolyte You'll need to ask Gitlab for support.

[hypolyte]

That's what I'm doing!

[BanzaiMan]

@hypolyte Sorry, but this is GitHub.
