rxjs 7.0.0 has error

[xp44mm]

when i upgrade rxjs 7.0.0, use webpack has error:

WARNING in ./node_modules/rxjs/dist/esm5/internal/Subscriber.js 122:34-47
export '__spreadArray' (imported as '__spreadArray') was not found in 'tslib'
....

and have a lot of error same as above. Although it is a warning, the program does not execute correctly and will be interrupted.

change rxjs version back to 6.6.7 the work properly again. my code too much to ditermine where is the problem.

Needs a minimal reproduction, as __spreadArray is definitely exported in the version of tslib in this package's package.json:

rxjs/package.json

Lines 129 to 131 in 4dda357

	"dependencies": {
	"tslib": "~2.1.0"
	},

https://github.com/microsoft/tslib/blob/2.1.0/tslib.js#L206-L210

https://github.com/microsoft/tslib/blob/2.1.0/tslib.js#L294

before i post this issue, i searched in website, and found this : microsoft/tslib#149

That issue has no reproduction either, so if anything is to be done about here, one will need to be provided.

In any case, it's clear that the export was added in the version of tslib upon which this package depends: https://github.com/microsoft/tslib/releases/tag/2.1.0

a reproduction: https://github.com/xp44mm/hyperscript-rxjs-test

just execute npm start on both 6.6.7 and 7.0.0 of rxjs.

Please provide a repro that does not contain packages published from what appears to be a private repo. This is on npm, but the GitHub projects are private:

https://www.npmjs.com/package/hyperscript-rxjs

I won't be installing it. Please provide a minimal repro that uses only well-known open-source packages.

FWIW, I've tweaked a small CRA-based harness that I have on this notebook to use RxJS 7.0.0 and have confirmed that it is installed with tslib 2.1.0 and - when type checked with TypeScript 4.2.4 and compiled with react-scripts 3.4.1 - it works fine. That leads me to believe that any problem is specific to your build process or to the tool versions used in said process. I don't believe that there is a problem that can be addressed here, in RxJS.

I'm using pure js project instead of ts, I've added dependency packages tslib into package.json, and the problem is solved.

It's something with your configuration. CRA builds using Babel, not TypeScript. It should not be necessary to add tslib when it's added as an RxJS dependency.
