Hmm, do you have a reproduction I can look at? There is probably something else wrong that leads to this to happen.

Merged for now since the guard probably does help, but technically this should only happen if there are dynamic import calls that were not properly processed in the transform step.

I am running a quite complex setup (vitepress + plugins + monorepo + aliases) while I have tried the repro from the minimal setup but found no luck. My use case is that I am aliasing my packages in the monorepo to the source entry rather than the dist, which works fine in vitepress v0.10.7 and vite v2.0.0-beta.12. Still not sure where the problem is, but the workaround fix for me. I will keep an eye on it and let you know if there is anything more I found. Thanks.
