Fix OpenCode Crash On Startup In Ubuntu 25.04
Experiencing crashes when starting OpenCode on Ubuntu can be frustrating. This article provides a comprehensive guide to diagnosing and resolving the issue, specifically addressing the "SyntaxError: Invalid or unexpected token" error encountered in Ubuntu 25.04. Whether you're a developer, a student, or just someone who loves to tinker with code, this guide will walk you through the steps to get OpenCode up and running smoothly.
Understanding the Issue
When OpenCode crashes on startup with a "SyntaxError: Invalid or unexpected token" error, it typically indicates a problem with the execution of the OpenCode binary. This can stem from various sources, including file corruption, incompatibility with the system architecture, or issues with the Node.js environment. The error message itself suggests that the system is encountering an unexpected character or syntax error while trying to interpret the OpenCode executable. Pinpointing the exact cause requires a systematic approach to troubleshooting.
The error message SyntaxError: Invalid or unexpected token usually points towards an issue with how the binary file is being interpreted. In this case, it suggests that the system is trying to execute a file that isn't compatible with the current environment. This often happens when an executable built for a different architecture is run, or if the file has been corrupted during installation or download. It is crucial to verify the architecture compatibility and integrity of the OpenCode installation to address this problem effectively.
Furthermore, the environment in which OpenCode is running plays a significant role. Factors such as the Node.js version, the package manager (pnpm in this case), and the operating system itself can all contribute to startup crashes. Ensuring that these components are correctly installed and configured is essential. This involves checking the versions of Node.js and pnpm, confirming that they meet the requirements of OpenCode, and verifying that the operating system is properly set up to execute Node.js applications. Understanding the interplay between these elements can help in narrowing down the root cause of the crash.
Diagnosing the Crash
1. Verify System Architecture
The provided system information reveals an aarch64 architecture. It's crucial to ensure that the OpenCode version you're using is compatible with this architecture. If you've installed a version intended for a different architecture (like x64), it will likely result in a crash. To check the architecture, you can use the uname -m command in your terminal. This will output the machine hardware name, which should be aarch64 for the system in question. If the architecture is incorrect, you will need to download and install the correct version of OpenCode for your system.
2. Check OpenCode Installation
The installation path /home/agladysh/.local/share/pnpm/global/5/-pnpm/opencode-linux-arm64@1.0.72/node_modules/opencode-linux-arm64/bin/opencode indicates that OpenCode was installed using pnpm. Verify that the installation process completed without errors. You can try reinstalling OpenCode globally using pnpm to ensure all files are correctly placed and no dependencies are missing. To reinstall, you can use the command pnpm uninstall -g opencode-ai followed by pnpm install -g opencode-ai. This will remove the existing installation and install a fresh copy, potentially resolving any issues caused by incomplete or corrupted files.
3. Node.js Version Compatibility
OpenCode might have specific Node.js version requirements. The provided logs show Node.js v20.18.1 is being used. Check the OpenCode documentation or repository for compatible Node.js versions. If the version you're using is incompatible, you might need to use a Node.js version manager like nvm or n to switch to a compatible version. These tools allow you to easily install and switch between different Node.js versions, making it simple to match the requirements of OpenCode. Using a compatible Node.js version is critical for ensuring that OpenCode can run without encountering syntax or runtime errors.
4. File Permissions
Ensure that the OpenCode executable has the necessary permissions to run. You can use the chmod command to grant execute permissions. Navigate to the directory containing the opencode binary (e.g., /home/agladysh/.local/share/pnpm/global/5/-pnpm/opencode-linux-arm64@1.0.72/node_modules/opencode-linux-arm64/bin/) and run chmod +x opencode. This command adds execute permissions to the file, allowing the system to run it as a program. Without the correct permissions, the system will be unable to execute the binary, leading to startup failures.
5. Check for Corrupted Files
A corrupted installation can lead to the "Invalid or unexpected token" error. Try reinstalling OpenCode using pnpm. Additionally, verify the integrity of the downloaded package if possible. Corrupted files can occur due to various reasons, such as network issues during download or disk errors. Reinstalling ensures that you have a clean and complete set of files. If the problem persists, consider downloading the installation package again from the official source to rule out any issues with the original download.
Steps to Resolve the Crash
Based on the diagnosis, here are the steps to resolve the crash:
1. Reinstall OpenCode
First, uninstall OpenCode globally:
pnpm uninstall -g opencode-ai
Then, reinstall it:
pnpm install -g opencode-ai
This ensures that you have a fresh installation, resolving any potential file corruption issues. Reinstalling is a straightforward way to replace potentially problematic files with known good copies, which often resolves startup crashes.
2. Approve Builds
Run the pnpm approve-builds -g command and ensure OpenCode is selected and approved. This step is crucial for allowing OpenCode to run if it requires specific permissions or approvals within the pnpm environment. Approving the builds ensures that pnpm trusts the OpenCode binaries and allows them to execute without restrictions.
3. Verify Node.js Version
Check the OpenCode documentation for the recommended Node.js version. If your current version is incompatible, use nvm or n to switch to a compatible version. For example, if OpenCode requires Node.js 18, you can use nvm install 18 and nvm use 18 to switch to that version. Using the correct Node.js version is critical for OpenCode to run correctly, as different versions may have different features and behaviors.
4. Set Execute Permissions
Navigate to the OpenCode binary directory and set execute permissions:
cd /home/agladysh/.local/share/pnpm/global/5/-pnpm/opencode-linux-arm64@1.0.72/node_modules/opencode-linux-arm64/bin/
chmod +x opencode
This allows the system to execute the OpenCode binary. Without execute permissions, the system will not be able to run the program, resulting in a crash.
5. Test OpenCode
After performing these steps, try launching OpenCode again by simply typing opencode in your terminal. If the crash is resolved, OpenCode should start without any issues. If the problem persists, you may need to investigate further, considering other potential causes such as system-level conflicts or hardware issues.
Additional Troubleshooting Steps
If the above steps don't resolve the issue, consider the following:
1. Check System Logs
Examine system logs for any error messages related to OpenCode. Logs can provide valuable insights into the cause of the crash, highlighting specific issues or conflicts. Common log locations include /var/log/syslog and /var/log/kern.log. Analyzing these logs can reveal underlying problems that are not immediately apparent.
2. Update System
Ensure your Ubuntu system is up-to-date. Outdated system packages can sometimes cause compatibility issues. Running sudo apt update followed by sudo apt upgrade will update your system to the latest packages, potentially resolving any conflicts or dependencies that are causing the crash.
3. OrbStack Configuration
Since you're using OrbStack, ensure that the virtual machine is properly configured and has sufficient resources allocated. Insufficient memory or CPU allocation can lead to performance issues and crashes. Review the OrbStack settings and adjust the resources allocated to the Ubuntu VM as needed. Additionally, ensure that OrbStack is running the latest version, as updates often include bug fixes and performance improvements.
