Error: Could not locate the bindings file. Tried:

Question

I ran into the following error while trying to run my electron app that contains my express app.

Error: Could not locate the bindings file. Tried:

I think the issue has to do with serialport module, for without it being required everything works fine.

Answer 1

You need to rebuild the serialport module as it uses different V8 headers than Electron.

First you will need to set up a node-gyp toolchain (https://github.com/nodejs/node-gyp)

Next, install any version of Visual Studio.

Open a command window and change directory to node_modules/serialport within your project.

Enter this command with the appropriate variables:

node-gyp rebuild --target=<electron_version> --arch=<arch> --dist-url="https://atom.io/download/atom-shell" --msvs_version=<visual_studio_year>

For an example this is the command I use when rebuilding:

node-gyp rebuild --target=1.2.5 --arch=x64 --dist-url="https://atom.io/download/atom-shell" --msvs_version=2013

I had a similar problem. My solution: I got more specific about which version of nodejs I was using. I had the latest release (at this writing) 13.8 and I had the same problems as the OP.

So I installed nvm and started using it to pick my nodejs.

$ nvm install --lts 
$ nvm use --lts
Now using node v12.16.0

The current Long Term Support version (at this writing) is 12.6. I redid npm install for the app and after that I had no problems with the serial port. Theoretically, I could have kept nvm'installing different version of nodejs until I got the one that worked.
