openclaw - 💡(How to fix) Fix Skill 环境变量未注入到 exec 子进程 [1 participants]

TL;DR

Modify the exec tool to automatically inject environment variables from skills.<name>.env into the subprocess environment for skill-related commands.

Guidance

• Identify the exec tool's current implementation and determine how it handles environment variables for subprocesses.
• Consider modifying the exec tool to parse the openclaw.json configuration file and inject the required environment variables for skill-related commands.
• Alternatively, explore modifying the skill executor to handle environment variable passing uniformly.
• Verify that the modified solution works by testing the skill script with the expected environment variables.

Example

// Example of how the exec tool could be modified to inject environment variables
const exec = require('child_process').exec;
const openclawConfig = require('./openclaw.json');

exec('node ~/.openclaw/skills/tavily-search/scripts/search.mjs "test"', {
  env: {
    ...process.env,
    ...openclawConfig.skills.tavily.env
  }
}, (error, stdout, stderr) => {
  // Handle the result
});

Notes

The proposed solution assumes that the exec tool is responsible for launching the subprocess and that modifying it to inject environment variables is feasible. Additionally, the example code snippet is a simplified illustration and may require adjustments to fit the actual implementation.

Recommendation

Apply a workaround by modifying the exec tool to inject environment variables, as this approach addresses the specific issue without requiring a version upgrade or significant changes to the existing codebase.
