Cocoapods: Pod install returning error

Created on 15 Dec 2014  ยท  7Comments  ยท  Source: CocoaPods/CocoaPods

Hi everyone,

I'm new to iOS programming and I wanted to use the _Mutual Mobile Drawer Controller_ for a test application. Unfortunately I have the following error showing up. Juste to make sure I tried to remove the MMDrawer dependency but that did not change anything.
I searched on the issues already encountered but there was not any explanation, just some bug fix commits.

If you need any other info just ask.

Thank you for your support.

Report

  • What did you do?

Running "pod install" command.

  • What did you expect to happen?

Download the dependencies described by my Podfile.

  • What happened instead?

The following error occurred: _NoMethodError - undefined method `downcase' for nil:NilClass_.

There's something wrong with your checkout of the master repo:

Repositories : master -  @ fatal: Not a git repository (or any of the parent directories): .git

You should be able to repair this by doing:

$ sudo rm -fr ~/.cocoapods/repos/master
$ pod setup

I tried what you said but each time I'm trying to do a pod setup I have the following error:

[!] /usr/bin/git clone 'https://github.com/CocoaPods/Specs.git' master --depth=1

Cloning into 'master'...
error: Could not resolve host: (nil); nodename nor servname provided, or not known while accessing https://github.com/CocoaPods/Specs.git/info/refs?service=git-upload-pack

fatal: HTTP request failed

Knowing that I tried to download manually the Specs but I probably miss something since I have the same error as previously described when opening this issue.

There seems to be some kind of network problem going around on your side. Better take it to Stack Overflow, as this is not really a CP issue.

Delete pods folder & podfile.lock file.
Reinstall pods.

This solved my problem.

In my case, it was not possible to delete Podfile.lock, because I cannot update the pod libs.

Updating Ruby and Cocoapods resolved the issue.
