so, for the record and any future viewers.
I was using gem 2.7.7

$ gem --version
2.7.7

This was fixed by running

gem update --system 2.7.6

some more detail:

I get it with a podspec that was published some months ago, as well as with a podspec that I'm trying to update

trying to update this one to 1.2.2 (no changes other than the two instances of the version string)

I have tested with cocoapods 1.5.3 and 1.6.0.beta.2

$ pod lib lint

 -> HSTestingBackchannel (1.2.2)
    - ERROR | [iOS] unknown: Encountered an unknown error (Malformed version number string ) during validation.

  #  These will help people to find your library, and whilst it
  #  can feel like a chore to fill in it's definitely to your advantage. The
  #  summary should be tweet-length, and the description more in depth.

  s.name         = "HSTableView"

  s.summary      = "A simpler, more elegant UITableView using objects, blocks instead of delegates"

  # This description is used to generate tags and improve search results.
  #   * Think: What does it do? Why did you write it? What is the focus?
  #   * Try to keep it short, snappy and to the point.
  #   * Write the description between the DESC delimiters below.
  #   * Finally, don't worry about the indent, CocoaPods strips it!
  s.description  = <<-DESC
A simpler, more elegant UITableView. Rows are managed by objects. Things happen with blocks.

Your whole table is declared up front with no need for delegates

The table view uses a responder chain to provide settings. Any setting can be set at the row level, the section level or the table level.

This allows simple configuration at the table level, and easy customisation at the row level.

Blocks are used for tap handlers, delete handlers, etc.

Default (and coloured) accessories are supported

HSTableView is suitable for situations where there is a known finite number of rows (although the number can change). It doesn’t support infinite scrolling tables (you’ll have to use UITableView and delegates for that!)

did you try pod lib lint ??

ok - so different results on different systems.
any suggestions?

so perhaps a ruby 2.4.0 issue???

@ConfusedVorlon still works for me in ruby 2.4.0 :|

any further info I can give?

did you see the 'RuntimeError - can't modify frozen String' error in the --verbose output?

Maybe this is a duplicate?

gem 2.7.7 can not run cocoapods 1.3.x . 1.4.x
you should install rubygem in 2.7.6

knox picture knox on 2 Nov 2018

yes - that fixes it. Thank you.

fwiw, this still feels like a bug to me.

  • It's fine for cocoapods not to run on gem 2.7.7
  • it is not fine for cocoapods to fail without saying why
ConfusedVorlon picture ConfusedVorlon on 2 Nov 2018

so, for the record and any future viewers.
I was using gem 2.7.7

$ gem --version
2.7.7

This was fixed by running

gem update --system 2.7.6
