Hello, do you have tried one of the following solutions:

To fix this,

1. install the .NET Framework 2.0 SDK,
2. install Microsoft Visual Studio 2005
3. add the location of the component to the system path if it is installed elsewhere. [C:\Users\GoodWorkLabs\Desktop\ecar-ba

I have solved this. If you notice this part of the command else (node "" rebuild ) what I think is happening is that it is incorrectly evaluating if not defined npm_config_node_gyp as false and trying to run nothing instead of node-gyp. What you need to do is define your npm_config_node_gyp variable. You can do this like so:
export npm_config_node_gyp=<PATH_TO_NODE_GYP_PACKAGE_FOLDER> remember that Windows will need double backslashes. For me, it looked like this:
export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp

There is another step after my fix. When executing my code, the expat bindings were missing. To fix it, add the bin folder and node-gyp executable to the npm_config_node_gyp variable and run node-gyp rebuild in the node_modules\node-expat folder. e.g.
export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp\\bin\\node-gyp.js
cd node_modules\node-expat
node-gyp rebuild
