RubyGems安装错误的代码

Question

When I install the gem ipa_reader the code does not install correctly. In the file /lib/ipa_reader/ipa_file.rb , the code that I get is

Zip::ZipFile.foreach(file_path) { |f| info_plist_file = f if f.name.match(regex) } Zip::ZipFile.foreach(file_path) { |f| info_plist_file = f if f.name.match(regex) } . Which I guess is from an older version. What I should get, and what shows up on github is

Zip::File.foreach(file_path) { |f| info_plist_file = f if f.name.match(regex) }.

What is going on?

Gemfile

source 'https://rubygems.org'

Answer 1

When you are installing from rubygems you are downloading stable 0.7.1 version, while at github there is latest development version. If you want to use this one (although it is not recommended to live on the bleeding edge), specify git url in your gemfile

gem 'ipa_reader', git: 'https://github.com/schlu/Ipa-Reader.git'

This looks like a mistake from the gem author. A github repo is not synched to rubygems, so the gem published to rubygems does not necessarily have to be the exact same thing as on github.

You can easily tell bundler to user the code from github, by doing:

gem 'ipa_reader', github: 'schlu/Ipa-Reader'
