Android Studio中Dart依赖English_words出现Target URI不存在问题求助

Hey there, I’ve dealt with this exact error a bunch of times when working with Dart/Flutter in Android Studio. Let’s walk through the most reliable fixes step by step:

1. Double-Check Your pubspec.yaml Syntax #

YAML is super picky about indentation and spelling—this is the most common culprit. Make sure your pubspec.yaml has the package listed correctly under dependencies, with proper 2-space indentation (no tabs!) and a valid version number:

dependencies:
  flutter:
    sdk: flutter  # Only include this if it's a Flutter project
  english_words: ^4.0.0  # Use the latest version available on pub.dev

2. Manually Run pub get #

Sometimes Android Studio’s auto-pub-get doesn’t trigger properly. Try either:

• Click the Pub get button in the top-right corner of the pubspec.yaml editor
• Open the terminal at your project root and run:

  # For Flutter projects
  flutter pub get
  
  # For pure Dart projects
  dart pub get
  

3. Verify Spelling and Case #

Double-check that you’ve written english_words correctly—no typos like english_word, EnglishWords, or other variations. The package name is all lowercase with an underscore.

4. Clear IDE Cache and Restart #

Corrupted IDE cache can cause weird issues like this. Here’s how to fix it:

• Go to File > Invalidate Caches...
• Check the box for Invalidate and Restart
• Let Android Studio restart, then try running pub get again.

5. Check Network Connection & Pub Mirror (if needed) #

The english_words package is hosted on pub.dev, so you need a stable internet connection to pull it. If you’re in a region where pub.dev is slow or unreachable, configure a pub mirror (like Aliyun’s) in your terminal:

dart pub config set pub-hosted-url https://mirrors.aliyun.com/dart-pub/

Then run pub get again.

6. Reset pubspec.lock (Last Resort) #

If none of the above works, delete the pubspec.lock file in your project root, then run pub get again. This forces Dart to re-resolve all dependencies from scratch.

If you still see the error, check the terminal output after running pub get—it’ll usually give a more specific clue about what’s wrong (like a missing SDK or network issue).
