I am unable to flash binary from the CLI on MacOS. I have attempted to reinstall and update both NodeJS, particle-cli, as well as have used nvm to attempt to run this with different versions of node, and I am getting the same message: > $ particle flash --serial electron\_firmware\_1478487240813.bin > Error loading command /usr/local/lib/node\_modules/particle-cli/commands/SerialCommand.js Error: Module version mismatch.

What if you try using dfu-util instead? ```auto particle flash --usb electron_firmware_1478487240813.bin ``` ---

Well, that does get me the end goal, which is to flash the device, so thank you for that. That being said, I still get some errors - e.g the, "Expected 48 got 46" error. I'm bothered by the fact that there is something screwy with NodeJS-particle-cli when the last time I worked with this about a month ago, there were no problems. Could it be that the most recent update of NodeJS is not compatible with particle-cli or something? > Error loading command /usr/local/lib/node\_modules/particle-cli/commands/SerialCommand.js Error: Module version mismatch.

This error is caused by an issue with `serialport`, and is because a serialport binary for your version of node could not be found. What happens if you try reinstalling Particle-cli using this command: ```auto sudo npm install -g node-pre-gyp npm serialport particle-cli ``` ---

Patrick, It looks like it was successfully reinstalled. Do you still get the same error when you try to do a serial command? ---

Since I was able to accomplish uploading my firmware via DFU, I am moving on to my next issue, and currently working on getting data sent to the Google Cloud via the Particle Integration, re: [https://docs.particle.io/tutorials/topics/google-cloud-platform/](https://docs.particle.io/tutorials/topics/google-cloud-platform/) I will go back and connect my device to serial later today. ---

Thread is quite old but for others having this issue I can confirm that the above command fixes it. I was facing this issue after updating my node.js installation on Windows 10 for another project and suddenly my Particle CLI started reporting errors. Running the install command mentioned above fixed it right away 😄
