Could not resolve "deepmerge"

[varunsavaliya]

I am facing one issue in this package while staring my project using npm start.
`
Could not resolve "deepmerge"

node_modules/ngx-lightweight-charts/fesm2022/ngx-lightweight-charts.mjs:7:22:
  7 │ import deepmerge from 'deepmerge';
   You can mark the path "deepmerge" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle.
   D:\Projects\trading-view-frontend-new\node_modules\vite\node_modules\esbuild\lib\main.js:1651

`

Waiting for any help.

I'm presuming you're using the default npm start that's set up to run ng serve in your package.json 'scripts'?

deepmerge is a dependency of this library (it's listed in the peerDependencies of its package.json) and should have been installed when running npm install - so should already be in your node_modules.

I'm not sure why that wouldn't be the case, unless possibly you had an error when running npm install?

[jamesbrobb]

Not sure if this might be the reason?

npm/cli#4934

[varunsavaliya]

Yes, this might be the issue. After installing deepmerge it's solved.
but it should be auto-installed because it is a peer dependency of the package.

can you make it compatible with the angular 18 version? Currently, it supports 17 only.

I'm hoping to have a look at creating an v18 version this weekend, i'll let you know once it's done
