Windows Lib Build Not Correct

[incutonez]

Describe the bug

For reference, please see this repo. In the repo, I have a sample library that I'm building with vite. When it gets built, it includes 3 JS files:

• classes.js
• index.js
• injectionKeys.js

The respective type files are also included, but they're not important. When I build this on Windows 10 using npm 8.15.0 and node 16.17.0, I get a strange result. In index.js on line 2, where it's supposed to import injectionKeys.js, it actually just adds the code const AppConfigKey = Symbol("AppConfig");. This is obviously problematic because the symbols are not unique if I'm then importing injectionKeys.js outside of the lib. When I build this on Ubuntu, I do not get this issue.

Furthermore, if I build this with rollup (with what I believe is almost the same configuration) using npm run build:rollup, I don't get this issue on Windows.

Do note that I'm using vite@2.9.15 because of the known issue with lib builds in v3.

• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Changing build.rollupOptions.input to

      input: {
        index: path.resolve(__dirname, 'src/components/index.ts'),
        injectionKeys:  path.resolve(__dirname, 'src/InjectionKeys.ts'),
        classes:  path.resolve(__dirname, 'src/classes/AppConfig.ts')
      },

seems to work. Maybe it's a similar to rollup/rollup#4591.

That is very interesting... it does indeed fix the issue. Thanks for that workaround!
