rollup-plugin-require-context not working properly in Windows system compile environment

[shenyi-dra]

Hi elcarim, i have facing the below issue for my current usage in Windows System.

Based on the different path seperator, in mac or linux system, the sepatator is '/', but in Windows Systme, the path.sep is '\'.

In resolve-require-code.js, the genRequireCode will trying to generate the import strings
normal the require.context('packages/', true, /.vue$/) works on below folder structure.
eg.
pacakges/alert/src/index.vue
packages/button/src/index.vue

but in windows system case.
it will become
packages\alert\src\index.vue
pacakges\button\src\index.vue

and after the genRequireCode executed, the import string moduleProps will become below,
'./alert\src\index.vue': require_context_module_0_0,
'./button\src\index.vue': require_context_module_0_1'

And the keys methods the extract the keys from the import modules will trying to convert the string and get rid of the '\' in Windows System.

req.keys = function() {
   return Object.keys(map);
};

And at the end when i using the
const files = require.context('packages/', true, /.vue$/)
files.keys().forEach(key => {
console.log(key); // each key become ./alertsrcindex.vue, all the windows separator is get rid of by the Object.keys method.
})
