@cmnstmntmn This is the way postcss-import works; postcss-import throws an error when a file isn't found. This behavior has received some controversy, but we've never decided if it should be changed or not.

Anyhow, closing since this is due to postcss-import, not postcss-cli.

Hey there, just noticed your comment in gitter; I didn't realize you were talking about watch mode, sorry.

Yes, this is something we should look into.

Agreed, this shouldn't error. It's really messing with my mojo. 😬 😜 For real though, I have a BUNCH of watching cli scripts for different tasks (rollup, pug/jade, sass), and this is the one that kills my main watching process (for multiple scripts) everytime it errors.

Watch should convey the error, but keep on a watching.

PR welcome, I just haven't gotten a chance to fix this yet.

Word.
