On my production instance, when i do bench update. it gives following error

frappe@erpnext-production:~/frappe-bench$ bench build
yarn run v1.16.0
$ FRAPPE_ENV=production node rollup/build.js
module.js:487
    throw err;
    ^

Note: I tried to follow all the suggestions present on discuss ex. [post1] (Error: Cannot find module 'rollup' - #4 by tony1) but this solutions doesn’t work in my case.

My version:
Ubuntu 16.04.6 LTS

Thanks! @saurabh6790 for your valuable input. I did make some progress. With every bench build it kept on throwing what was missing. So I ran following commands from bench folder

sudo npm install rollup
sudo npm install rollup-plugin-buble
sudo npm install rollup-plugin-uglify
sudo npm install rollup-plugin-vue

and finally bench build now gives below error!

/home/frappe/frappe-bench/node_modules/rollup-plugin-vue/dist/rollup-plugin-vue.js:118
        ...createVuePartRequest.defaultLang,

It seems you are running an older version of node. Please make sure your Node version is atleast 8.12.0

Check node version by running node -v

Thanks! @netchampfaris , i am able to make progress with above help but still not reached finishing lines.

nvm install 8.12.0

Then did bench build it throws other errors
Error: ENOENT: no such file or directory, open ‘/home/frappe/frappe-bench/apps/frappe/node_modules/moment/min/moment-with-locales.min.js’

@ashish-greycube

  1. Make sure you are running node version 8.12.0 or greater
  2. Change directory to frappe folder by running cd frappe-bench/apps/frappe
  3. Delete your node_modules folder in your frappe app folder by running rm -rf node_modules
  4. Change directory to frappe-bench folder by running cd ../..
  5. Run bench setup requirements --node
  6. Run bench build

Thanks!! @netchampfaris yes, it does solve the issue of having incorrect node_modules and bench build failing due to it.

bench setup requirements --node
