安装Cocoa Pod失败，提示无法找到目标JustCall

First, let's break down what's happening here—you're hitting this error when running pod install or pod update:

Unable to find a target named JustCall, did find GPUImage and GPUImageFramework

And your Podfile looks like this:

platform :ios, '11.0'
use_frameworks!
target 'JustCall' do
  pod 'TesseractOCRiOS', '4.0.0'
end

Here are the most common fixes to resolve this issue:

• Double-check your Xcode target name
  The target name in your Podfile must match exactly (including capitalization, spaces, and punctuation) the target name in your Xcode project. Open your .xcodeproj file, look in the left sidebar under "Targets"—if the target is named something slightly different (like justcall with lowercase, or Just Call with a space), update your Podfile to match that exact name.

• Clean up Pod caches and re-install
  Sometimes old Pod caches can cause mismatches between your Podfile and project targets. Run these commands in your project's root directory (where the Podfile lives):

  pod deintegrate
  pod clean
  pod install
  

  pod deintegrate removes all existing Pod integrations from your project, pod clean clears cached Pod files, and pod install starts fresh.

• Verify your Xcode project has the JustCall target
  It's possible the JustCall target was accidentally deleted or never created in the first place. Open your Xcode project, go to File > New > Target to create the JustCall target if it's missing, then re-run pod install.

• Check for conflicting target configurations
  If your project has multiple targets (like the GPUImage ones mentioned in the error), make sure your Podfile isn't accidentally referencing a target that doesn't exist. Double-check that the target 'JustCall' do ... end block is correctly placed and not nested inside another target block.

Give these steps a try—most of the time, it's either a simple name mismatch or a cache issue that's easy to fix!
