I have the same problem. Freezing to 10.0.1.0 for now (which is a working fine version)

Can any of you share your execjs runtime information? Thanks!
(node or miniracer & version)

[morgoth]

 node -v
v12.19.0

Same problem.

node -v
v14.12.0

This happens when input css contains source map annotation, which postcss will try to load for chaining.

Execjs runtimes are not able to read files, the browser build of postcss didn't handle this .

I'll release a patch very soon, thanks everyone for reporting this.
