Cocoapods: Unable to find a specification for X depended upon by Y) during validation

[vicmosin]

Here is the case...
I have a pod, which depends on two pods:

1. Some public pod located at github and not published at cocoapods yet
2. A pod from cocoapods

Pod file contains two definitions:

pod 'SomeLib', :git => 'https://github.com/SomeLib/SomeLib.git'
pod 'SomeLib2', '~> 3.0'

and it works fine. But in case of .podspec it's not so trivial, since it accepts only cocoapods-published definitions so I can't specify github repo. As a result, I get two errors:

1. Encountered an unknown error (Unable to find a specification for SomeLib depended upon by MyLib) during validation
2. fatal: Remote branch 1.0.0-SNAPSHOT not found in upstream origin and I really don't know why it tries to use this branch and not master...

I found this issue, but --sources doesn't help since it still has error # 1

The --sources option is for specifying additional spec repos, not for specifying a Pod repo. So if you are passing https://github.com/SomeLib/SomeLib.git in your case that will not work.

@neonichu Yes, I tried to use it with pod spec lint but it didn't help as I described

[neonichu]

As I said, this is not the use case for --sources that's why you're receiving an error. You'll need to either set up a private spec repo (see https://guides.cocoapods.org/making/private-cocoapods.html) or publish your dependencies on trunk. There's no third option.

I also met this error, and the Thirdlib which is not private spec repo.

@yangshengtao Have there been any solutions with this? i'm currently also struggling with this

[pjocer]

@EMart86 I have this issue too.....

[majeedyaseen]

in my case, it got solved by including the source URL of the library at the first line of pod file

source 'https://github.com/myrepo.git'
