I understand that the following command will update a single pod: pod update <podname>
. However this also updates the dependencies of other pods (pods that were not included in the update command) that you have previously installed. Is there a way to update a single pod and leave all other dependencies alone?
This question is related to
cocoa
cocoapods
podfile
pod-install
I'm using cocoapods version 1.0.1
and using pod update name-of-pod
works perfectly. No other pods are updated, just the specific one you enter.
pod update POD_NAME
will update latest pod but not update Podfile.lock
file.
So, you may update your Podfile with specific version of your pod e.g pod 'POD_NAME', '~> 2.9.0'
and then use command pod install
Later, you can remove the specific version naming from your Podfile and can again use pod install
. This will helps to keep Podfile.lock
updated.
just saying:
pod install
- for installing new pods,
pod update
- for updating existing pods,
pod update podName
- for updating only specific pod without touching other pods,
pod update podName versionNum
- for updating / DOWNGRADING specific pod without touching other pods
To install a single pod without updating existing ones-> Add that pod to your Podfile and use:
pod install --no-repo-update
To remove/update a specific pod use:
pod update POD_NAME
Tested!
Just a small notice.
pod update POD_NAME
will work only if this pod was already installed. Otherwise you will have to update all of them with
pod update
command
This is a bit of an outlier and not likely to be what the OP was dealing with, but pod update <podname>
will not work in all cases if you are using a local pod on your computer.
In this situation, the only thing that will trigger pod update
to work is if there is a change in the podspec file. However, making a change will also allow for pod install
to work as well.
In this situation, you can just modify something minor such as the description or summary by one letter, and then you can run the install or update command successfully.
You can never get 100% isolation. Because a pod may have some shared dependencies and if you attempt to update your single pod, then it would update the dependencies of other pods as well. If that is ok then:
tl;dr use:
pod update podName
Why? Read below.
pod update
will NOT respect the podfile.lock
. It will override it — pertaining to that single podpod install
will respect the podfile.lock
, but will try installing every pod mentioned in the podfile based on the versions its locked to (in the Podfile.lock).This diagram helps better understand the differences:
The major problem comes from the ~>
aka optimistic operator.
Podfile
is not enoughSome might think that specifying exact versions of their pods in their Podfile
, like pod 'A', '1.0.0'
, is enough to guarantee that every user will have the same version as other people on the team.
Then they might even use pod update
, even when just adding a new pod, thinking it would never risk updating other pods because they are fixed to a specific version in the Podfile
.
But in fact, that is not enough to guarantee that user1 and user2 in our above scenario will always get the exact same version of all their pods.
One typical example is if the pod A
has a dependency on pod A2
— declared in A.podspec
as dependency 'A2', '~> 3.0'
. In such case, using pod 'A', '1.0.0'
in your Podfile will indeed force user1 and user2 to both always use version 1.0.0 of the pod A, but:
A2
in version 3.4
(because that was A2
's latest version at that time)pod install
when joining the project later, they might get pod A2
in version 3.5
(because the maintainer of A2
might have released a new version in the meantime).
That's why the only way to ensure every team member work with the same versions of all the pod on each's the computer is to use the Podfile.lock
and properly use pod install
vs. pod update
.The above excerpt was all derived from pod install vs. pod update
I also highly recommend watching what does a podfile.lock
do
Make sure you have the latest version of CocoaPods installed. $ pod update POD
was introduced recently.
See this issue thread for more information:
$ pod update
When you run
pod update SomePodName
, CocoaPods will try to find an updated version of the pod SomePodName, without taking into account the version listed inPodfile.lock
. It will update the pod to the latest version possible (as long as it matches the version restrictions in your Podfile).If you run pod update without any pod name, CocoaPods will update every pod listed in your Podfile to the latest version possible.
So because pod update SomePod
touches everything in the latest versions of cocoapods, I found a workaround.
Follow the next steps:
Remove SomePod
from the Podfile
Run pod install
pods will now remove SomePod
from our project and from the Podfile.lock
file.
Put back SomePod
into the Podfile
Run pod install
again
This time the latest version of our pod will be installed and saved in the Podfile.lock
.
