error at handle_route()

Module not found: Error: Can't resolve 'c:AppsTestareasvelte_sappermyappoutes/about.html' in 'c:\Apps\Testarea\svelte_sapper\myapp.sapper'

Also error messages suggest a typo:
outes rather than routes

[Rich-Harris]

It's not a typo — it's almost as if it thinks path\to\routes is path\to[CARRIAGE_RETURN]outes? Am very confused by this.

It also looks like maybe it's resolving .sapper as ${cwd}.sapper rather than ${cwd}\.sapper. Which if true is, ugh. Windows!

[tomcon]

Think you're right re. carriage returns @Rich-Harris

It was wrapping in places in the output but I wasn't sure if it was my editor!

[rtorr]

This is an issue on Windows 10 as well (probably know that)

[Rich-Harris]

I didn't, but I assumed as much! I'm not really any closer to figuring out what's going on, so if you have any ideas...

[Rich-Harris]

Ok, I've released a new version of Sapper — 0.2 — and the tests appear to be passing in Windows now. Could you try updating please?

As well as bumping the version, you'll need to add the following to package.json:

  "scripts": {
    "dev": "node server.js",
+    "build": "sapper build",
    "start": "cross-env NODE_ENV=production node server.js",
+    "prestart": "npm run build",
    "cy:run": "cypress run",
    "cy:open": "cypress open",
    "test": "run-p --race dev cy:run"
},

At least then if it still fails we'll be able to figure out if it's a build-time problem or a run-time problem.

[Rich-Harris]

Can you try a couple of things please? Try running npm run build to see if you get the same error without starting the server. And then, edit your package.json like this...

"scripts": {
-    "dev": "node server.js",
-    "build": "sapper build",
-    "start": "cross-env NODE_ENV=production node server.js",
+    "dev": "cross-env SAPPER_DEST=testdir node server.js",
+    "build": "cross-env SAPPER_DEST=testdir sapper build",
+    "start": "cross-env NODE_ENV=production SAPPER_DEST=testdir node server.js",
    "prestart": "npm run build",
    "cy:run": "cypress run",
    "cy:open": "cypress open",
    "test": "run-p --race dev cy:run"
  }

...and try npm run dev to see if it works in dev mode, and npm start to see if it works in prod mode. I'm wondering if webpack on windows somehow gets confused by the leading . character?

[Rich-Harris]

(I say that because c:\Apps\Testarea\svelte_sapper\my-app.sapper looks like it's gluing the directories together)

[tomcon]

After trying to debug webpack for 1-2 hours I'm feeling quite ill

1. These may/may not help:

HarmonyImportDependency {module: null, request: "c:AppsTestareasvelte_sappermy-app\routes/api/blog/[…", userRequest: "c:AppsTestareasvelte_sappermy-app\routes/api/blog/[…", …}
importedVar:"__WEBPACK_IMPORTED_MODULE_1_c_AppsTestareasvelte_sappermy_app_outes_api_blog_slug_js__"
loc:SourceLocation {start: Position, end: Position}
module:null
range:Array(2) [78, 178]
request:"c:AppsTestareasvelte_sappermy-app\routes/api/blog/[slug].js"
type:"harmony import"
userRequest:"c:AppsTestareasvelte_sappermy-app\routes/api/blog/[slug].js"

2. Notice slashes going in both directions on the following + import statements

// watch_compiler()
compiler.outputpath = "c:\Apps\Testarea\svelte\_sapper\my-app\.sapper/client"
 
"import about from 'c:\Apps\Testarea\svelte\_sapper\my-app\routes/about.html';
import * as api_blog_$slug$ from 'c:\Apps\Testarea\svelte\_sapper\my-app\routes/api/blog/[slug].js';
import * as api_blog_index from 'c:\Apps\Testarea\svelte\_sapper\my-app\routes/api/blog/index.js';
import blog_$slug$ from 'c:\Apps\Testarea\svelte\_sapper\my-app\routes/blog/[slug].html';
import blog_index from 'c:\Apps\Testarea\svelte\_sapper\my-app\routes/blog/index.html';
import _ from 'c:\Apps\Testarea\svelte\_sapper\my-app\routes/index.html';

export { about,api_blog_$slug$,api_blog_index,blog_$slug$,blog_index,_ };"

3. perhaps relevant (or not)?

Ah, so there is a place in the code where it's assuming / and not path.sep. Weird that the tests pass on Appveyor.

I've created two branches — could you try installing from these and seeing what happens?

yarn add https://github.com/sveltejs/sapper#possible-windows-fix-1 && yarn run build
yarn add https://github.com/sveltejs/sapper#possible-windows-fix-2 && yarn run build

(or npm install if you're using npm instead, obvs)

Ok, I think I have it! Can you try

yarn add https://github.com/sveltejs/sapper#possible-windows-fix-3 && yarn run build

please? You might also need to set emitCss to false in webpack.client.config.js and remove the ExtractTextPlugin (possibly a secondary issue).

I haven't totally got to the bottom of this, but preliminary investigation suggests webpack is to blame. I don't think it likes absolute import paths in Windows.

[tomcon]

Looks like you've cracked the main problem! just a tweak required @Rich-Harris

[Rich-Harris]

Wahoo! The remaining errors are related to the emitCss stuff I think — I've just updated svelte-loader, can you try installing the latest version and seeing if that fixes it? Thanks

[Rich-Harris]

I haven't released the fix yet! So starting from scratch with npx degit will blow away the fix in the most recent branch. Bear with me...

[Rich-Harris]

0.2.3 is released, and I've updated the deps in this repo... fingers crossed 🤞

[Rich-Harris]

Released 0.2.4 which should also fix the HMR stuff, and a new version of svelte-loader which does the same thing for generated CSS files

[rtorr]

Will be testing on holiday. Thanks!
