Ruby gem Xcodeproj在項目保存時引發異常

Question

在嘗試Xcodeproj時，我發現了一個錯誤，可能是由於濫用API引起的。 您能指出我做錯了嗎？

require 'xcodeproj'

project = Xcodeproj::Project.new("test.xcodeproj")
new_target_name = 'test'
project.new_target(:framework, new_target_name, :ios)
project.save

target_to_remove = project.targets.select {|t| t.name == new_target_name}.first
project.targets.delete(target_to_remove)
project.save

target_to_remove.remove_from_project

此代碼段給我以下錯誤消息。

/usr/local/lib/ruby/gems/2.4.0/gems/xcodeproj-1.4.4/lib/xcodeproj/project/object/configuration_list.rb:101:in `ascii_plist_annotation': undefined method `isa' for nil:NilClass (NoMethodError)

    from /Users/testuser/Desktop/XcodeprojTest/test.rb:10:in `<top (required)>'
    from -e:1:in `load'
    from -e:1:in `<main>'

有任何想法嗎？

這對我有用：

targets_to_remove = project.targets.select { |target| target.name == new_target_name }
targets_to_remove.each { |target| target.remove_from_project }

我相信只需調用remove_from_project就可以刪除它，並且可以正確清理所有引用。
