Windows10部署Sawtooth供应链遇JScript编译错误800A03EA求助

Hey there, let's break down why you're hitting this error and how to fix it quickly:

What's Causing the Error? #

The error code 800A03EA is a syntax error from Microsoft's JScript engine. This happens because Windows is trying to run the index.js file with its built-in script host (WScript/Cscript) instead of Node.js. The ledger_sync module in Sawtooth Supply Chain is a Node.js application, so it requires Node.js to execute—not Windows' native JScript engine, which doesn't understand modern JavaScript syntax used in Node.js projects.

Step-by-Step Fixes #

1. Stop Using Windows' Default Script Host to Run the File #

Never double-click the index.js file directly, or use "Open with > Windows Script Host" to launch it. Instead:

• Open Command Prompt or PowerShell.
• Navigate to the ledger_sync directory using the cd command (e.g., cd C:\path\to\sawtooth-supply-chain\ledger_sync).
• Run the file with Node.js explicitly:

  node index.js
  

2. Verify Node.js is Installed (and Compatible) #

Sawtooth Supply Chain v0.10.1 typically works best with Node.js versions 8.x or 10.x. To check if you have Node.js installed:

• Run this in your terminal:

  node -v
  

If no version number appears, install a compatible Node.js version first.

3. Ensure Dependencies Are Installed (For Local Debugging) #

If you're running the ledger_sync module locally (not through Docker), install the required dependencies first:

• In the ledger_sync directory, run:

  npm install
  

Wait for all dependencies to install, then run node index.js again.

4. Check Docker Compose Configuration #

If the error pops up during docker-compose up, verify your docker-compose.yml file:

• Ensure the ledger_sync service uses a Docker image that includes Node.js (like the official Sawtooth images or a custom image with Node.js pre-installed).
• Confirm the container is mounting the correct directory and running the Node.js command to start index.js (not relying on Windows' script engine inside the container).
