Cocoapods: Unable to find a specification for a pod that exists

[idokleinman]

Updated to Cocoapods to 0.38.0 and pod trunk push-ed my latest pod 'Spark-SDK', completed successfully but now trying to install this pod in a project fails:
Unable to find a specification for Spark-SDK

doubled checked name and all is OK, seems like a case sensitivity issue though nothing changed on my side/podspec except for bumping version

What is wrong?

[segiddins]

Is the platform in your Podfile compatible with the spec's minimum deployment target?

[idokleinman]

Didn't specify platform in podfile. as a test just added
pod 'Spark-SDK'

[segiddins]

Then the deployment target in your Xcode project might not be compatible

[idokleinman]

Appreciate the help but I don't think this is the issue
podspec specifies:
s.platform = :ios, '7.1'
project is 8.0, tried now also 7.1 but always get:
[!] Unable to find a specification for Spark-SDK

https://github.com/CocoaPods/Specs/blob/master/Specs/Spark-SDK/0.3.0/Spark-SDK.podspec.json

[segiddins]

Can you try running pod repo update?

[idokleinman]

Sure:

Updating spec repo `master`
Already up-to-date.

then pod install with same results.

Interesting find:
when I change the Podfile to read:
pod 'spark-sdk'
(simply lowercase)
I get:
[!] Unable to find a specification for Spark-SDK/Helpers (= 0.3.0) depended upon by spark-sdk

looks like interpreter progressed to the next part of podspec (reading subspecs) which means something weird is going with case sensitivity.

[idokleinman]

Any feedback appreciated as currently no users can install/use my pod library

[segiddins]

I can't reproduce this whatsoever, sorry. It installs fine for me.

[idokleinman]

Oh, the strangest thing! What might be causing that?

[segiddins]

What's the output of pod repo list, pod search Spark-SDK, and pod spec cat Spark-SDK?

[idokleinman]

Here:

I'd just try mv ~/.cocoapods/repos/master/Specs/spark-sdk ~/.cocoapods/repos/master/Specs/Spark-SDK, as it looks like you've changed the capitalization of your spec at some point?

[idokleinman]

That did the trick! Thanks a lot!
I did change capitalization I think, that was on 0.1 several months ago, didn't have any issues installing the pod locally up till now. Nevermind, it's all good now since my uesrs are not blocked and me neither now.
Thank you

[rymanalo]

I found this thread because I had the same problem just now when trying to
pod install or pod update

the following:
pod "Spark-SDK"

I used:
mv ~/.cocoapods/repos/master/Specs/spark-sdk ~/.cocoapods/repos/master/Specs/Spark-SDK

then pod install worked fine.

[rchatham]

Ran into this same issue when trying to point to a specific repository and branch other than the official release in a .podspec!

[fabiomassimo]

@rchatham I think I have the same issue , I'm trying to install a pod directly from its git url and specific branch but I get back

[!] Unable to find a specification for 'MyPod'.

If I try to install the same pod without specifying any option everything works as expected.
I'm using CocoaPods v1.1.1.

Below there is an small edited version of the stacktrace I got:

Is it there something else I can provide to help with this issue?

[orta]

Did you try running the git commands it outputted, and going into the folder to verify that the Podspec is not there?

[fabiomassimo]

@orta yes I tried and the Podspec is actually there. Also double checked any capitalisation issue in the name.

[fabiomassimo]

Quick update:
By following all the steps from the stacktrace I published, I have just found out that while the Podspec is available at the command:

/usr/bin/git clone {git_url} /var/folders/40/419ts8s15_zd6l_wl45sr__c0000gn/T/d20161105-94038-12yjji --template=

It actually disappears when this commands is executed:

/usr/bin/git -C /var/folders/40/419ts8s15_zd6l_wl45sr__c0000gn/T/d20161105-94038-12yjji checkout --quiet 3123a22aa417f89f066a7869a45ca58179fae0a2

I'm not sure how it determines to checkout 3123a22aa417f89f066a7869a45ca58179fae0a2, any idea?

EDIT:

When ls branches (/usr/bin/git ls-remote {git_url} {git_branch}}) the output is

3123a22aa417f89f066a7869a45ca58179fae0a2  refs/heads/feature/{git_branch}
d09e6d25cd840884155321d8cd86c5e9e64f5dec  refs/heads/{git_branch}

I'm interested in the second one but the first one is picked.

EDIT 2:

A solution would be to run the git ls command by pre appending the refs/heads/ to avoid conflicts like in this case. What do you think? Is this valid material for a small PR?

My proposal is to run the ls command as follow:

/usr/bin/git ls-remote {git_url} refs/heads/{git_branch}

[HelaGone]

I just updated the repo via pod repo update and voila, it works!!

[nick3389]

@fabiomassimo I have the same issue. trying to install a private pod from a specific branch. Have you found a solution?
