Cocoapods points to wrong version - ruby

Question

I had some problems with one version of the project. I've found this answer where someone suggest steps to remove all cocoapods-connected stuff from the machine and reinstall it. I did follow the steps:
$ 'pod --version'
0.36.1
$ gem list --local | grep cocoapods
cocoapods (0.39.0.rc.1, 0.38.2, 0.38.1, 0.37.2)
cocoapods-core (0.39.0.rc.1, 0.38.2, 0.38.1, 0.37.2)
cocoapods-downloader (0.9.3, 0.9.1)
cocoapods-plugins (0.4.2)
cocoapods-search (0.1.0)
cocoapods-stats (0.6.2, 0.5.3)
cocoapods-trunk (0.6.4, 0.6.1)
cocoapods-try (0.5.1, 0.4.5)
$ gem uninstall cocoapods // and all others from the list above
The problem is that when i again grep all cocoapods, the list was equal to upper one, nothing disappeared.
$ sudo gem uninstall cocoapods
Select gem to uninstall:
1. cocoapods-0.37.2
2. cocoapods-0.38.1
3. cocoapods-0.38.2
4. cocoapods-0.39.0.rc.1
5. All versions
> 5
$ pod --version
// here was the error command not found, so everything fine
$ sudo gem install cocoapods
Fetching: cocoapods-0.38.2.gem (100%)
Successfully installed cocoapods-0.38.2
Parsing documentation for cocoapods-0.38.2
Installing ri documentation for cocoapods-0.38.2
Done installing documentation for cocoapods after 2 seconds
1 gem installed
$ pod --version
Could not find proper version of cocoapods (0.36.1) in any of the sources
Run `bundle install` to install missing gems.
But why does it want me to install 0.36.1? Anyway, as it asked, I did:
$bundle install
Installing cocoapods-core 0.36.1
Installing cocoapods-downloader 0.8.1
Installing cocoapods-plugins 0.4.1
Installing cocoapods-trunk 0.6.0
Installing cocoapods-try 0.4.3
Installing cocoapods 0.36.1
// Many "using" dependencies
So now when I run:
$ pod --version
0.36.1
And I'm stuck :) Why can't I have newest release version? Maybe pod --version points to the newest version of cocoapods-core instead of only cocoapods, so everything is ok and I have the correct version?

Answer 1

Check if you use Gemfile and there is specified the version of
cocoapods.
You can use specific version by pod *version* action. For example: pod _1.5.0.beta.1_ update or pod _1.5.0.beta.1_ install

For anyone coming to this in an attempt to update cocoapods. After doing all of the above I wasn't able to get this resolved. I then headed to the resolved answer and being unwilling to remove RVM, I tried to resolve this issue another way.
I found that my issue did indeed lie in my Gemfile.
First, run
gem install cocoapods to ensure you have the latest version, or whatever specified version you were looking for downloaded.
Second, ensure your projects Gemfile hasn't specified a cocoapods version number and instead simply specifies it as:
gem "cocoapods"
If yours doesn't, change this and run bundle update to regenerate the Gemfile.lock file and your problem should be solved. If not, go ahead and delete the Gemfile.lock file altogether and then run bundle update. You can easily check to see which gem version will be loaded by opening the Gemfile.lock file and searching for cocoapods-core <version number here>
At this point, you can go into your project and run
pod setup
and then check the cocoapods version with
pod --version
and now FINALLY you are free to run
pod install
to replace the Podfile.lock file and get back to your happy dev life. Hope that helps someone and saves them from burning hours.

It seems something got messed up in my ruby version. I still have no idea what and why. I've managed to fix it via this solution: https://stackoverflow.com/a/25021772/849616. After it everything works correctly.

Answer 4

You might face this issue when it comes migrating to a higher Swift version. Assuming that you already have cocoapods installed, you probably need to run bundle update command (possibly with sudo).
For more details, you could check: https://guides.cocoapods.org/using/a-gemfile.html
Additionally, I'd suggest to do the following:
Install the latest Xcode version.
Clear derived data (not just clean project) in your project.
Run pod update command.

Answer 5

I have the same problem.
In my project, pod --version and gem which cocoapods always return diffrence version.
All I had to do is remove Gemfile.lock in my project and bundle install again. It removed the locked cocoapods version and install a new one.
Hope that helps some one here.

I ran pod install and I've got this error:
Could not find proper version of cocoapods (1.11.3) in any of the sources
and I ran:
bundle install
after that pod install worked properly
