Can't resolve './dataview.js' error importing @stdlib/stats

[alexebl]

Description

I have an angular project where I want to use @stdlib/stats library
I have installed the library via npm:
npm install @stdlib/stats
and then included it within one component using import statement
import {dists} from '@stdlib/stats/base';

when I trying to compile project I'm getting this error:

./main.js:24:21-45 - Error: Module not found: Error: Can't resolve './dataview.js' in '\node_modules@stdlib\assert\has-arraybuffer-support\lib'

lokking in node_modules path, I could not find dataview.js either, so it seems that something changed in sources and needs to be adapted

👋 Hi there! 👋

And thank you for opening your first issue! We will get back to you shortly. 🏃 💨

@alexebl Heya! Are you looking to use many of the distributions of @stdlib/stats/base/dist/* or just a couple? If the latter, you can install the individual distributions you want to use directly. E.g.,

$ npm install @stdlib/stats-base-dists-normal

If the former, then we can investigate a bit further. My guess is that a published package is out-of-sync with its dependencies.

@alexebl Created a test repository with a new Angular project to reproduce the reported issue:

https://github.com/Planeshifter/angular-stdlib-stats-test

However, importing

import {dists} from '@stdlib/stats/base';

and using one of its functions works without any issues for me, so the problem must be somehow tied to your project's configuration. Do you use any other @stdlib packages besides stats? It would be great if you could create a reproducible example so we can figure out what is going on.

[alexebl]

yes, it seems to be issue of broken project configuration,
I have just created another new Angular project and copied the package.json from the faulty project, that one works.
I then deleted node_modules and package-lock.json from the faulty one and reinstalled everything, still not working
So, it seems to be a problem of my configuration.

Can we close this issue then?

[alexebl]

Actually I was able to reproduce the error.
Steps:

1. ng new test

2. npm install @stdlib/stats

3. add to src\app\app.component.ts following statements:
   import {dists} from '@stdlib/stats/base';
   import {kstest} from '@stdlib/stats';

   constructor() {
   let cdf = dists.normal.cdf(2,5,3);
   let test = kstest( [ 2.0, 1.0, 5.0, -5.0, 3.0, 0.5, 6.0 ], 'normal', 0.0, 1.0 )
   }
   => compilation failed with:
   ./node_modules/@stdlib/assert/has-arraybuffer-support/lib/main.js:24:21-45 - Error: Module not found: Error: Can't resolve './dataview.js' in 'C:\Source\PowerBiVisuals\Development\node_modules@stdlib\assert\has-arraybuffer-support\lib'

the error occured after I have added the kstest function call, not sure if additional parts need to be installed for kstest

@alexebl Thank you for these detailed instructions. We can reproduce the problem and will look into a solution.

In the meantime, you may try using the standalone packages, i.e. @stdlib/stats-kstest and @stdlib/stats-base-dists-normal-cdf for the above example.

[kgryte]

@alexebl Did you try using the standalone packages?

@Planeshifter Is this issue resolved now that we've released new minor versions of the top-level namespaces?

[Planeshifter]

This issue is now resolved. Closing this issue thread.
