It seems the js error occurs when we have this config, but the css error shows up always

This is truely caused by this define but I think it's not a bug. It works like #define in C/C++, macro definitions are essentially macro substitutions, all keywords process.env will be replaced with the value of itself. So the expression process.env = {}; will be replaced to a expr like { ...process.env } = {}; so a syntax error will be thrown.

What's the difference with vite? when I use vite to build, it works fine. But when migrated to farm, it is stuck.

We'll take a look

The css issue will be fixed in @farmfe/core@1.3.28. But define whole process.env is not supported in farm, it's unsafe, you can use env config to specify the env you want to define
