Then I don't know. @julien-f might be around tomorrow to check if it rings any bell.

edit: as usual, double check you are on latest commit from master.

@aqua-calc Make sure the repo is clean and there are no untracked files (git status).

@julien-f I did fresh install, with config exported from the original xenorchestra server and then imported into the new server

@aqua-calc, I have the same issue....
building at commit level a204b6fb3f1236dc5f4519a734c4d5c8f99f9e9c
and I am getting the same error. Cleaned all a did a fresh git pull --ff-only

yarn run v1.22.5
$ node dist/cli.mjs
(node:3448) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use node --trace-warnings ... to show where the warning was created)
/root/xen-orchestra/packages/xo-server/dist/xapi/mixins/index.js:2
import _gpu, * as __gpu from "./gpu";
^^^^^^

SyntaxError: Cannot use import statement outside a module
etc...

The yarn build command produces those files (there is something wrong somewhere, why does the build produces index.js when there is the index.mjs?)

So

delete /packages/xo-server/dist/xapi/mixins/index.js (rm index.js)
delete /packages/xo-server/dist/xapi/mixins/index.js.map (rm index.js.map)
remove the import and export statements referencing index.js from file /packages/xo-server/dist/xapi/mixins/index.mjs (nano index.mjs)

and did the same as above for /packages/xo-server/dist/api/index.js
and same for /packages/xo-server/dist/xo-mixins/index.js

And then yarn start and it starts and orchestra is fine as far as I can see.

Not sure if that's the best but it got me going . Hope this helps someone.

@jmrapin You still hav untracked index.js files in xo-server/src, please remove them and rebuild.

jmrapin

@julien-f well spotted. Thanks!
All good now.

aqua-calc

@jmrapin Thank you!

iron_man

@jmrapin good job! after removing the untracked files, problem wasn't solved, and then i followed your instructions and it worked, thanks a lot!

This error can happen in different cases depending on whether you're working with JavaScript on the server-side with Node.js , or client-side in the browser. There are several reasons behind "Cannot use import statement outside a module" error, and the solution depends on how you call the module or script tag.

Add type="module" inside the script tag

When working with ECMAScript modules and JavaScript module import statements in the browser, you'll need to explicitly tell the browser that a script is module. To do this, you have to add type="module" onto any ‹script› tags that point to a JavaScript module. Once you do this you can import that module without issues.

<script type="module" src="./index.js"></script>

If you are working on Node.js or react applications and using import statements instead of require to load the modules, then ensure your package.json has a property "type": "module" as shown below.

{
  // ...
  "type": "module",
  // ...
}
