I’m working on a website that is running sage 8.5.1, and I’m running into some issues with gulp watch.

I’ve done all of the following:  
Install gulp and Bower globally with npm install -g gulp bower  
Navigate to the theme directory, then run npm install  
Run bower install

But when I run gulp watch, I get these issues:  
Error: Cannot find module ‘gulp-cli’

Any suggestions?

We’ll need to know what operating system you’re running, and also what you’ve done to troubleshoot this issue so that we’re not re-treading ground you’ve already walked.

Hi MWDelaney,

Thanks so much for getting back to me.

I’m running Mac OS High Sierra, and I’ve managed to fix the issue above. But I am now getting this error when running gulp watch within the template directory:  
gulp watch[8188]: …/src/node\_contextify.cc:633:static void node::contextify::ContextifyScript::New(const FunctionCallbackInfo\<v8::Value\> &): Assertion `args[1]-\>IsString()’ failed.

Abort trap: 6

I have done a bit of Googling, which suggested downgrading node.js, but that didn’t seem to help either so I stuck with the suggested version on the node website.

Thanks,  
Meg

Sage 8 requires Node 4.5. We recommend using `nvm` to switch between Node versions as needed. Make sure you’ve followed the [getting started documentation](https://roots.io/getting-started/docs/macos-development-environment-sage/) for Sage to install `nvm`. Those docs are written for Sage 9, so when they say to install Node `lts/carbon`, use `4.5` instead.
