[node.js] cannot find module "lodash"

Today I tried to learn more about Google Web Starter Kit so I followed these instructions and after a lot of fight and problem I just tried to start a local server (the first task we’ll look at is: $ gulp serve.) and received this error:

C:\gwsk>gulp serve

Error: Cannot find module 'lodash'

Honestly I'm completely lost here, so any help is pretty welcome. I'm new to node.js, to gulp, I just wanted it to try GWSK but turn into a headache :(... I'm a web designer not developer....

I got the error above and after fixing it I got an error for lodash/merge, then I got an error for 'license-check-and-add' then I realized that according to https://accessibilityinsights.io if I ran the below command, it installs all the missing pacakages at once! Then running the yarn build command worked smoothly with a --force parameter with yarn build.

yarn install

yarn build --force

Yarn build --force execution:

Reinstall 'browser-sync' :

rm -rf node_modules/browser-sync
npm install browser-sync --save

For me, I update node and npm to the latest version and it works.

Maybe loadash needs to be installed. Usually these things are handled by the package manager. On your command line:

npm install lodash 

or maybe it needs to be globally installed

npm install -g lodash

If there is a package.json, and in it there is lodash configuration in it. then you should:

npm install

if in the package.json there is no lodash:

npm install --save-dev

I found deleting the contents of node_modules and performing npm install again worked for me.

though npm install lodash would work, I think that it's a quick solution but there is a possibility that there are other modules not correctly installed in browser-sync.

lodash is part of browser-sync. The best solution is the one provided by Saebyeok. Re-install browser-sync and that should fix the problem.

The above error run the commend line\

please change the command $ node server it's working and server is started
