Windows 10下构建Autodesk Forge RCDB遇node-gyp错误

Looking at your error log, the core issue is a malformed npm_config_node_gyp environment variable — notice the duplicate node prefix in the path: node C:\Users\me\AppData\Roaming\npm\node_modules\node-gyp\bin\node-gyp.js. This causes Node.js to look for a non-existent module path, breaking the canvas@1.6.10 installation via node-gyp.

Here's a step-by-step fix tailored to your scenario:

1. Correct the npm_config_node_gyp Environment Variable #

• Open Command Prompt (CMD) as your regular user account (skip admin unless your npm was installed with admin rights)
• Run this command to check your current setting:

  echo %npm_config_node_gyp%
  

• If the output includes a leading node (like node C:\Users\me\...), fix it with this temporary command (replace with your actual node-gyp path):

  set npm_config_node_gyp=C:\Users\me\AppData\Roaming\npm\node_modules\node-gyp\bin\node-gyp.js
  

• For a permanent fix: Go to System Properties > Advanced > Environment Variables, find npm_config_node_gyp in the user variables, and remove the extra node prefix from the path.

2. Clean and Reinstall Dependencies #

• Delete the node_modules folder and package-lock.json (or npm-shrinkwrap.json) from your project directory
• Clear npm's cache to remove any corrupted files:

  npm cache clean --force
  

• Re-run the installation command:

  npm install
  

3. Verify Node-gyp's Windows Prerequisites #

Even if you've checked these before, double-critical dependencies that often cause node-gyp failures on Windows:

• Install Python 2.7 (not Python 3.x) and ensure it's added to your system PATH
• Install Visual Studio Build Tools (or Visual Studio 2015+) with the "Desktop development with C++" workload enabled
• Reinstall global node-gyp to ensure it's up-to-date:

  npm install -g node-gyp
  

4. Fallback: Use Prebuilt Canvas Package #

If the above steps still fail, replace the canvas dependency with a prebuilt version to bypass node-gyp entirely:

• Open your project's package.json
• Replace "canvas": "^1.6.10" with "canvas-prebuilt": "^1.6.10"
• Repeat the clean/reinstall steps from section 2
