Oct 24, 2025 by SLV Team 44 views

Hey guys! 👋 If you're using the Claude Code SDK, then you might have run into a little hiccup recently. The package that holds the SDK has moved, and this is a heads-up to make sure you're all set and don't get stuck! Let's dive into what's changed and how to get your code working smoothly again. Basically, the Claude Code SDK has changed its package, so you need to update to the new one to keep things running. This change affects anyone using the SDK, particularly those who are integrating it into their projects. The move ensures that the Claude Code SDK stays up-to-date and offers the best performance.

The Big Shift: Why the Package Change? 🤔

So, what's the deal? Why did the Claude Code SDK change packages? Well, it's all about keeping things organized and making sure you get the best experience possible. The old package, @anthropic-ai/claude-code, is no longer where the magic happens. The new home for the SDK is @anthropic-ai/claude-agent-sdk. This change helps streamline the way you interact with the SDK and ensures that all the latest features and updates are readily available. This helps with better organization and future-proofing the Claude Code SDK. You might be asking, "Why the change?" The simple answer is to improve the overall functionality and organization of the Claude Code SDK. The new package is part of a broader effort to make the Claude Code SDK more robust, easier to use, and more aligned with the latest developments. It's like moving to a new house: you get more space, everything is updated, and it's easier to find things. But you've got to know where the new house is, right? This move isn't just about changing a name; it's about setting the stage for future improvements and ensuring that the SDK remains a top-notch tool for developers like you. If you were using the original package, you'll need to update your code to point to the new location to make sure things continue to work seamlessly. This keeps your code running and lets you take advantage of any improvements and updates in the new package.

Impact on Your Projects

The impact on your projects is straightforward but important: If you've got code that uses the @anthropic-ai/claude-code package, it will break. Your IDE or build system will start throwing errors, complaining that it can't find the SDK files. But don't worry! This is an easy fix, and we'll walk you through it. Your project will be unable to find the Claude Code SDK. Make sure that all of your imports and any references to the SDK are updated. The main issue here is the package location. After the upgrade, you will be able to take advantage of the latest features and updates. This ensures the best integration with your project and all the newest features of the Claude Code SDK.

Fixing the Problem: Your Step-by-Step Guide 🛠️

Alright, let's get you back on track. Here's a quick guide to get your code updated and working with the new Claude Code SDK package:

Update Your Package Dependency: First things first, you need to change your package declaration. Open your package.json file (or the equivalent file for your project) and find the @anthropic-ai/claude-code dependency. You'll need to remove it and then add the new dependency: @anthropic-ai/claude-agent-sdk. Use your project's package manager (like npm or yarn) to install the new package. For example, in your terminal, run npm install @anthropic-ai/claude-agent-sdk or yarn add @anthropic-ai/claude-agent-sdk. This updates the dependency list and ensures that the correct version of the SDK is used. This process ensures that your project uses the latest Claude Code SDK version and all its benefits. Make sure you're getting the most up-to-date version of the SDK. If you are using a package manager like npm or yarn, make sure that you update the package with the appropriate commands. This ensures that you have access to the latest improvements, fixes, and features that Anthropic has released.
Update Your Imports: Once the new package is installed, you'll need to update your import statements in your code. Anywhere you were importing from @anthropic-ai/claude-code, you'll now need to import from @anthropic-ai/claude-agent-sdk. For example, if you had import { ClaudeCode } from '@anthropic-ai/claude-code';, you'll change it to import { ClaudeCode } from '@anthropic-ai/claude-agent-sdk';. This simple change tells your code to look for the SDK in the new location. This ensures the correct functionality and is a crucial step in resolving the issue. This is crucial for fixing the bug and making sure that all the SDK functionality is available to your project. This also avoids all of those pesky “module not found” errors. These imports are the paths that your project uses to access the SDK, so updating them is absolutely essential for the code to run correctly. Double-check all of your import statements, and make sure that you've updated all of them to reflect the new package location.
Test Your Code: After updating the package and imports, it's time to test. Run your code and make sure everything works as expected. Check for any errors or unexpected behavior. If everything is set up correctly, your code should compile and run without any issues. This allows you to verify that the Claude Code SDK is correctly integrated into your project. Now you should make sure that the functions and features are working as expected after the package change. This quick test can spot any issues that might have been missed in the previous steps. It's always a good idea to test after any significant updates. Make sure that your applications still behave as expected, and that you haven't introduced any regressions or bugs. Testing is super important to make sure everything's running smoothly!
Check the Documentation: If you run into any problems or need more detailed information, head over to the official documentation. This is your go-to resource for all things Claude Code SDK, including migration guides, API references, and troubleshooting tips. The documentation provides a comprehensive overview of the changes and how to navigate them. The documentation is the best source to find the most up-to-date information on the SDK. You'll find all the details you need to get things working right. The documentation is full of helpful information to guide you through the transition. It offers a detailed breakdown of the package change, including explanations of why the move was made and how it impacts your projects.

Handling Theia Versions

For those of you working with Theia, the latest versions should be compatible with the new package. Make sure you are using the latest master branch. If you run into any Theia-specific issues, check for updates or relevant plugins that might also need to be updated. Ensure your Theia environment is compatible with the latest version of the SDK and that all necessary configurations are updated to match the new package structure. In order to avoid potential compatibility problems, make sure you are using a compatible version of Theia. It's also important to verify that any relevant plugins or extensions within your Theia environment are updated to work with the latest version of the SDK. This is something that you should always be checking and ensuring it is up to date.

Troubleshooting Tips 💡

Still running into problems? Here are some quick troubleshooting tips:

Clear Your Cache: Sometimes, your build system or IDE might be holding on to old versions of the package. Try clearing your cache and restarting your development environment. This often fixes problems where the updated package isn't being recognized. Clearing your cache ensures that your project uses the most recent version of the SDK and that the correct files are loaded. This forces your system to fetch the latest version of the SDK, resolving potential conflicts caused by outdated cached files.
Double-Check Your Package Manager: Make sure you've installed the new package correctly using your package manager (npm, yarn, etc.). Double-check your package.json file to ensure the new dependency is listed. Using the correct commands ensures a clean installation. This also helps with resolving any dependency conflicts that may occur during the upgrade. Double-checking your package manager is a quick way to ensure you're not missing any required dependencies.
Verify Your Imports: Carefully review all of your import statements to ensure they point to the new @anthropic-ai/claude-agent-sdk package. A simple typo can cause big problems! This prevents those dreaded
