使用示例代码名称项目无法在 Eclipse 中构建 iOS Xcode 项目

Question

I was about to run the simulator in Eclipse on the example project (the initializer) on my MacBook. However when I tried to build the iOS Xcode project, it failed and asked for the installation of cocoapods. I followed the instruction using "sudo gem install cocoapods" but got another error, seeming to complain about the lack of necessary libraries and/or headers. I attached a portion of the stack trace for each error below.

Help is appreciated.

Answer 1

It seems that cocoapods is not installing for you. This appears to be a common issue, with multiple possible causes. See ERROR: Error installing cocoapods: ERROR: Failed to build gem native extension for a few different suggestions on getting past this.
