Usage with postcss-nested-vars plugin

[neoromantic]

So, I grew over postcss-simple-vars and need something more capable, and turned to postcss-nested-vars plugin.

However, when I try to enable it with this package, I get error:

=> Errors prevented startup:                  
   
   While processing files with nathantreid:css-modules (for target web.browser):

Here's my configuration:

"cssModules": {
"postcssPlugins": {
"postcss-import": {},
"postcss-mixins": {},
"postcss-each": {},
"postcss-cssnext": {},
"postcss-responsive-type": {},
"postcss-modules-local-by-default": {},
"postcss-modules-extract-imports": {},
"postcss-modules-scope": {},
"postcss-simple-vars": {
"fileOptions": ["style-globals.json"]
}
},
"ignorePaths": ["node_modules/(?!react-toolbox/lib)"],
"extensions": ["scss", "css"]
}

Any ideas?

I needed nested-vars to conditionally set sass variable to theme colors for different clients.

Suppose, I have my theme in some sass common file (colors.scss) that I include wherever I need it.

How could I redefine some variable conditionally? Only thing I have in mind, is to have these redefinements scoped by some global classname, and then just set this class on root element. But for that I need nested-vars. Is there any other way?

i just understood that nested-vars wont help me :(
