Cocoapods: pod lib create fails: uninitialized constant Nanaimo::Reader::StringScanner (NameError)

Created on 29 Oct 2016 · 24Comments · Source: CocoaPods/CocoaPods

Before you start, are you using the CocoaPods beta release? No
a lot has changed with Xcode 8 that is not backwards compatible.

Xcode 8 Status: Only works with CocoaPods 1.1.0
Swift 3: You need to add a .swift-version file, see the CHANGELOG
China: Use https://gems.ruby-china.org/ instead of https://gems.ruby-china.org/ for the RC see #5910

[x] I've read and understood the *CONTRIBUTING guidelines and have done my best effort to follow.

Report

What did you do?

Ran pod lib create <name>

Sort of creates it, but doesn't fill in the name or any info I provided

Cloning `https://github.com/CocoaPods/pod-template.git` into `test-lib`.

Ran sudo gem update
And then reran above, but receiving related error .. :/

gem list | grep plist
plist (3.2.0, 3.1.0)

gem list | grep xcodeproj
xcodeproj (1.4.0, 1.3.3)

Any thoughts?

Appreciate the help!

@MaximusMcCann You shouldn't need sudo if you're using rbenv. Now it looks like nanaimo is not in your gem path?

what's the output of gem list | nanaimo?

endocrimes on 29 Oct 2016

hmm...

gem list | nanaimo
zsh: command not found: nanaimo

MaximusMcCann on 29 Oct 2016

Please can you try gem install nanaimo -v 0.1.2 or use Bundler?

endocrimes on 29 Oct 2016

Looks like I must have set something up incorrectly to start :/

Had to refresh my shell

gem install nanaimo -v 0.1.2
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied @ rb_sysopen - /Users/a/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/nanaimo-0.1.2/.gitignore

nanaimo (0.1.2, 0.1.0)

reloaded shell, but still `read_from_path': cannot load such file -- nanaimo (LoadError)

MaximusMcCann on 29 Oct 2016

🤔 - I'm honestly not too sure. It looks like there's something funky with your ruby env. Could you try http://guides.cocoapods.org/using/a-gemfile.html?

endocrimes on 29 Oct 2016

Will try. Thank you for the help!

MaximusMcCann on 29 Oct 2016

Got bundle to work. The key: cannot add a hyphen to the pod name so test-lib failed, but testLib works!

Still not working without bundle exec, but that's on me. Thanks @DanToml for the quick help!

MaximusMcCann on 29 Oct 2016

Had to explicitly remove the old nanaimo 0.1.0. Now it works

I resolve this problem when i switch ruby version 2.1.1 to 2.2.4

theewind on 28 Apr 2017

Uninstalling old versions of Nanaimo worked!

DanielZanchi on 12 Jun 2017

Probably your project file is corrupted try to use https://github.com/Karumi/Kin to figure it out

$ gem uninstall nanaimo

Select gem to uninstall:
 1. nanaimo-0.2.3
 2. nanaimo-0.2.4
 3. nanaimo-0.2.5
 4. All versions

Uninstalled 0.2.3 and 0.2.5. Worked for me. Maybe having more than one version triggers the issue? Dunno.
