{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"path resolution fails on Windows","articleBody":"Compiled scripts produce `ERR_MODULE_NOT_FOUND` exceptions on all of my Windows machines. This seems to have something to do with the paths generated by the compiler and some unexpected behavior from racket/path.\r\n\r\nRacks is able to successfully compile the program, but when I try to run the module with Node, it errors out trying to import a file called 'untimecore.js'. I took a look through the compiled version of my racket code, and found this at the top of the file:\r\n\r\n`import * as $rjs_core from '..\\runtime\\core.js';`\r\n`import * as M0 from \"..\\runtime\\kernel.rkt.js\";`\r\n`import * as M1 from \"..\\collects\\racket\\private\\modbeg.rkt.js\";`\r\n\r\nThese aren't the intended paths, because the single back-slashes escape characters in the file names. This is why `'..\\runtime\\core.js'` becomes something like `'   untimecore.js'`.\r\nI have a working theory for why the paths are being generated this way, although I am new to the codebase, so it could easily be something else.\r\n\r\nI suspected this was a windows-specific problem, so I went looking for how these import statements are built. I found that the function `simple-module-path` in [util.rkt](https://github.com/racketscript/racketscript/blob/f3bddfb52d3a0229b9585db676d498f560eea658/racketscript-compiler/racketscript/compiler/util.rkt) can call `simple-form-path`, which in turn calls [simplify-path](https://docs.racket-lang.org/reference/Manipulating_Paths.html#%28def._%28%28quote._~23~25kernel%29._simplify-path%29%29).\r\n\r\nAccording to the documentation, simplify-path will replace `/` with `\\` on Windows, so it certainly seems like this might be the culprit. However, this isn't a bug with simplify-path but the intended behavior. It might be necessary to go through the code and differentiate between when a path is going to be used with the file system and when the path string is to be used in compiled javascript code.","author":{"url":"https://github.com/arthertz","@type":"Person","name":"arthertz"},"datePublished":"2021-07-27T22:35:39.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/249/racketscript/issues/249"}
