Won’t build using Svelte

[Mark2M]

I have a test frontend developed using Svelte and calling the Ollama API etc. There are no other dependancies or backend functionality other than local storage (for chat history).

It runs just fine in a development environment but won’t build.

I get the following errors on build:

error during build: RollupError: [vite-plugin-sveltekit-compile] node_modules/ollama/dist/index.js (11:13): "promises" is not exported by "__vite-browser-external", imported by "node_modules/ollama/dist/index.js".

Then further down: import { createHash } from 'crypto'; at getRollupError (file:///vercel/path0/node_modules/rollup/dist/es/shared/parseAst.js:376:41) at error (file:///vercel/path0/node_modules/rollup/dist/es/shared/parseAst.js:372:42) at Module.error (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:13654:16) at Module.traceVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:14102:29) at ModuleScope.findVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:11805:39) at ChildScope.findVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:6019:38) at ClassBodyScope.findVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:6019:38) at ChildScope.findVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:6019:38) at ChildScope.findVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:6019:38) at FunctionScope.findVariable (file:///vercel/path0/node_modules/rollup/dist/es/shared/node-entry.js:6019:38) Error: Command "npm run build" exited with 1

I did a quick search and found nothing at all…

Anyone know how to sort this out?

I recently merged a change that uses rollup to build a commonjs module. This looks like it could be a result of that.

I'd suggest trying to set ollama to version 0.4.9 in your package.json and see if it resolves the issue. Let me know if it does and I'll dig into why rollup could be causing this.

Hi.. tried 0.4.9 and 0.4.8 and neither would build:

Got this when setting version to 0.4.9:

I'm not sure this should still be open. The issue was down to me not using the correct "browser" api, I was trying to use the node version in the browser (should always read the readme). The exact answer seems to have been deleted.

Thanks for the update @Mark2M, closing this for now.
