Hi! Tried to install Phoenix on Manjaro for the first time using installation page. After installation If I don’t use flag --no-webpack, I meet

[info] Running TeacherWeb.Endpoint with cowboy 2.9.0 at 0.0.0.0:4000 (http)
[error] Could not start Node.js watcher because script "/home/pilot/Programs/webpunk/teacher/assets/node_modules/webpack/bin/webpack.js" does not exist. Your Phoenix application is still running, however assets won't be compiled. You may fix this by running "npm install" inside the "assets" directory.

If I run

npm install

in …/assets

I have no clue after two days trying to fix that.

Hello and welcome,

Maybe try to replace node-sass by sass in your assets.

cd assets
npm uninstall node-sass
npm i -D sass

Which version of Phoenix are You using?

Hi, thanks for answer and sorry for a late reply. My Phoenix version is 1.5.9. I’ve used your suggestion and gained new error Error: Node Sass version 6.0.0 is incompatible with ^4.0.0. Server is working but webpage looks terrible like html is broken.

what is the node version? node 14 and phoenix 1.5 should be ok.

5

Node version is v16.2.0

6

try downgrading to 14.

I’d recommend GitHub - nvm-sh/nvm: Node Version Manager - POSIX-compliant bash script to manage multiple active node.js versions.

7

I had similar issues using node v16 with Phoenix. v14 and v15 should be ok, though.

with 14 I have no issues, while I had some trouble with 15 (can’t remember what exactly went wrong)
