Error installing Rainforest (`file.metas['link']`) #13

AliSoftware · 2014-05-13T20:54:10Z

There is an error in the Rakefile@L417

file.metas['link'].first ➡️ Undefined method metas for #<Tempfile>

I just freshly cloned the repo, did execute rvm gemset create rainforest to have a clean gemset to start from, then followed the README instructions.

$ rvm current
ruby-2.0.0-p353@rainforest

$ rake --trace bootstrap
** Invoke bootstrap (first_time)
** Execute bootstrap
/Users/olivier/.rvm/gems/ruby-2.0.0-p353@global/bin/bundler

Can you try it without RVM and gemsets? There shouldn’t be a need for this, especially as you’re not doing any other Ruby dev, right?

AliSoftware · 2014-05-14T10:49:54Z

This doesn't change anything.

Looking at the API for OpenURI, it seems the method is misspelled. It should probably be just meta: http://apidock.com/ruby/OpenURI/Meta (the header fields).

Progress.

Hrmm, I have the feeling that the objects returned by OpenURI might have different APIs on different Ruby versions. @irrationalfab can you confirm?

In this case, assuming that @irrationalfab confirms that on other Ruby versions this does return an Array, it would have to be made compatible with all. I think this should help:

link = Array(file.meta['link']).first

The Kernel::Array() method wraps an object in an array, unless it’s already an Array.

AliSoftware · 2014-05-14T11:13:07Z

This seems to work, the rake script is cloning repos right now!

$ sed -n 417p Rakefile 
    link = Array(file.meta['link']).first
$ ruby -v
ruby 2.0.0p451 (2014-02-24 revision 45167) [universal.x86_64-darwin13]

alloy · 2014-05-14T11:17:03Z

Ok, let’s see what @irrationalfab says about why the code is as it is right now and then patch it accordingly.

AliSoftware · 2014-05-14T11:17:39Z

$ ri OpenURI::Meta#meta
 = OpenURI::Meta#meta

(from ruby core)
------------------------------------------------------------------------------

returns a Hash that represents header fields. The Hash keys are downcased for
canonicalization.

I believe that if there is only one header of a given header key (like link), it returns an String, and only returns an array if there are multiple values for the same header. But I'll wait for @irrationalfab validation before pushing the fix.

AliSoftware · 2014-05-14T11:22:47Z

Something strange about this Rakefile anyway:

The first time I tried to rake bootstrap, it stopped asking me to manually install bundler
So I did some sudo gem install bundler (even if I found it strange as I believe the gem was already installed) and ran rake bootstrap again

But then after cloning all the repositories, it failed on this:

gem install bundler
ERROR:  While executing gem ... (Gem::FilePermissionError)

So I sudo rake bootstrap to workaround the permission error, which did the trick but showed me this warning:

gem install bundler
Successfully installed bundler-1.6.2
Parsing documentation for bundler-1.6.2
1 gem installed
bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.

Seems strange that even if I manually installed bundler explicitly before running rake, it tried to install it again, right?

alloy · 2014-05-14T11:26:49Z

One of the repos Rakefile’s is probably trying to install Bundler as part of rake bootstrap which should not be done. It has to be installed manually before running rake bootstrap. Can you figure out which repo it is?

AliSoftware · 2014-05-14T11:29:40Z

Will try, but am a bit lost with all this code in multiple Rakefiles and all the repos 😉

If it helps, this was in the "Installing gems" section of the output:

There we go, it’s in the CLAide Rakefile: https://github.com/CocoaPods/CLAide/blob/master/Rakefile#L8.

AliSoftware · 2014-05-14T11:30:47Z

CLAide is the one: https://github.com/CocoaPods/CLAide/blob/master/Rakefile#L8

AliSoftware · 2014-05-14T11:31:18Z

Damn you shot first 😆

alloy · 2014-05-14T11:34:15Z

👯

So yeah, it probably use a check like this repo’s Rakefile has and print an error to install bundler. In any case, it should not try to install bundler.

AliSoftware · 2014-05-14T11:49:48Z

Just FYI, once I manually fixed both:

line 417 of Rainforest's Rakefile
the bootstrap task of CLAide's Rakefile to remove the sh gem install bundle line (but keep sh bundle install line)

I was finally able to complete the installation, confirmed by running CocoaPods/bin/pod --help

This still needs some official fix though
