claude-code - 💡(How to fix) Fix [BUG] Claude commands fail with EACCES permission denied error when creating files [1 participants]

Error: EACCES: permission denied, open '/path/to/project/test.py' at Object.openSync (node:fs:601:3) at Object.writeFileSync (node:fs:2249:35) at ClaudeCode.writeFile (/usr/local/lib/node_modules/@anthropic-ai/claude-code/dist/index.js:123:10) at async ClaudeCode.executeCommand (/usr/local/lib/node_modules/@anthropic-ai/claude-code/dist/index.js:456:5)

TL;DR

The most likely fix is to check and adjust the file system permissions for the project directory to ensure the Claude Code process has write access.

Guidance

• Verify the ownership and permissions of the project directory and its contents using ls -l to check if the user running the Claude command has write permissions.
• Check if the issue persists when running the Claude command with elevated privileges using sudo to isolate if it's a permission issue.
• Review the differences in file system permissions between the last working version (1.0.100) and the current version (1.0.123) to identify any changes that might be causing the issue.
• Consider resetting the permissions of the project directory to a more permissive state (e.g., chmod -R 755 my-project) to test if it resolves the issue.

Example

No specific code snippet is applicable in this case, as the issue seems related to file system permissions rather than code.

Notes

The fact that this is identified as a regression and worked in a previous version (1.0.100) suggests that a change in the Claude Code version might be the cause, potentially related to how file system interactions are handled.

Recommendation

Apply a workaround by adjusting the file system permissions to ensure the Claude Code process has the necessary write access, as the root cause seems to be related to permissions rather than a bug in the code itself.
