Invalid `Podfile` file: syntax error, unexpected keyword_end

Bắt đầu bằng cách tái hiện vấn đề trong _plugins/nativescript-version-number/src/platforms/ios/Podfile và so sánh với demo/platforms/ios/Podfile được tạo. Chạy npm run plugin.tscwatch và npm run demo.ios, sau đó truy vết cách Podfile của plugin được kết hợp với demo target. Công việc được hoàn tất khi Podfile được tạo có các khối target cân bằng và lệnh demo iOS hoàn tất mà không có lỗi cú pháp.

Which platform(s) does your issue occur on?

• iOS

Please, provide the following version numbers that your issue occurs with:

• CLI: 5.4.2
• Cross-platform modules: 5.0.0
• Runtime(s): tns-ios: 5.4.2
• Plugins (the demo app created by running npm run postclone):

  "dependencies": {
    "nativescript-theme-core": "~1.0.4",
    "nativescript-twilio-chat": "file:../src",
    "tns-core-modules": "~5.4.0"
  },
  "devDependencies": {
    "nativescript-dev-typescript": "~0.10.0",
    "nativescript-dev-webpack": "~0.24.0"
  },

Please, tell us how to recreate the issue in as much detail as possible.

• sudo gem install cocoapods (if not already installed)
• mkdir plugin-test
• cd plugin-test
• git clone https://github.com/NativeScript/nativescript-plugin-seed _plugins/nativescript-version-number
• cd _plugins/nativescript-version-number/src
• npm run postclone
• I entered twilio-chat for the plugin name and chose defaults (create a demo TypeScript app)
• create the following Podfile in _plugins/nativescript-version-number/src/platforms/ios (as per Twilio Programable Chat docs)

source 'https://github.com/CocoaPods/Specs'

target 'MyTarget' do
  pod 'TwilioChatClient', '~> 2.4.2'
end

• replace MyTarget with demo
• in 2 terminal windows, both in _plugins/nativescript-version-number/src, run:
• npm run plugin.tscwatch
• npm run demo.ios

Result: [!] Invalid 'Podfile' file: syntax error, unexpected keyword_end, expecting end-of-input.
The generated Podfile (_plugins/nativescript-version-number/demo/platforms/ios/Podfile) looks like this:

use_frameworks!

target "demo" do
end

end

# Begin Podfile - /www/plugin-test/_plugins/nativescript-version-number/demo/node_modules/nativescript-twilio-chat/platforms/ios/Podfile
source 'https://github.com/CocoaPods/Specs'

target 'demo' do
  pod 'TwilioChatClient', '~> 2.4.2'
end

# End Podfile
end

Removing the end in my Podfile, I still get the same error (and just one less end in the resulting Podfile).
At one point I even got a Duplicate target "demo" error, so I even tried removing the line target 'demo' do line from my Podfile, but still no luck, still got the [!] Invalid 'Podfile' file: syntax error, unexpected keyword_end, expecting end-of-input. error.
Even if I delete all content from my Podfile, to have it empty, I still get a bad resulting Podfile:

use_frameworks!

target "demo" do
end

end

# Begin Podfile - /www/plugin-testt/_plugins/nativescript-version-number/demo/node_modules/nativescript-twilio-chat/platforms/ios/Podfile

# End Podfile
end
