Goals

Install pods on a second machine.

Expected Results

On the first machine bundle exec pod update succeeded and updated the Podfile.lock accordingly. Doing a bundle exec pod install on a second machine with having the following in Podfile.lock

- Realm (3.19.0):
    - Realm/Headers (= 3.19.0)
  - Realm/Headers (3.19.0)
  - RealmSwift (3.19.0):
    - Realm (= 3.19.0)

is expected to just succeed without any errors.

Actual Results

bundle exec pod install --verbose

     You are in 'detached HEAD' state. You can look around, make experimental
     changes and commit them, and you can discard any commits you make in this
     state without impacting any branches by performing another checkout.

     If you want to create a new branch to retain commits you create, you may
     do so (now or later) by using -b with the checkout command again. Example:

       git checkout -b <new-branch-name>

More

The permissions inside of $TMPDIR for directories like the above are the following:

drwx------      2 <the-user>  staff      64 Oct  3 04:11 d20191003-96746-42crc8

These are the same permissions on both, the first machine and the second.

Deleting $TMPDIR/sync_bin and Pods/Realm/core should fix this.

[lunij]

rm -rf $TMPDIR/sync_bin did the trick. Thanks

Hey - looks like you forgot to add a T-* label - could you please add one (if you have access to add labels)?
