Is there any way to mix multiple versions in one project?

[vaynevayne]

Currently, the old code uses 4.5, and we want to upgrade to 6. How can I coexist two versions in one project?

Probably is not going to work. I would say no absolutely no

Is this method okay? @asturur
Known conditions: fabric installed via npm

npmalias

If you are very careful that the code and imports do not get mixed maybe. But needs to be 2 different apps running in 2 contexts. Not the same app using fabric 4 and 6.

I don't quite understand what app and context refer to in this sentence. Mine is a pc h5 page. In a window environment, I don't need to consider server-side rendering and other situations.
