[typescript] Broken vue3 + rollup + typescript

[iassasin]

• Rollup Plugin Name: typescript
• Rollup Plugin Version: 6.0.0 (current latest)
• Rollup Version: 2.29.0
• Operating System (or Browser): linux if neccesary, reproduces at bundle build time
• Node Version: 14.13.1
• Link to reproduction (⚠️ read below): https://github.com/iassasin/vue3-rollup-ts-bug

Expected Behavior

Working bundle.

Actual Behavior

[!] (plugin typescript) Error: Could not load .../MainView.vue?vue&type=script&lang.ts (imported by MainView.vue): Debug Failure. False expression: Expected fileName to be present in command line

Additional Information

Also reported to vue-rollup-plugin (vuejs/rollup-plugin-vue#400), but after some debug I suggess that bug is in plugin-typescript, because with rollup-plugin-typescript2 bundle built successfuly. Difference to plugin-typescript2 is official plugin-typescript uses function ts.getOutputFileNames, that produces failed assert.

Please see if any of these issues with the same error message addresses your issue: https://github.com/rollup/plugins/search?q=Expected+fileName+to+be+present+in+command+line&type=issues

@shellscape, thanks for fast answer! Only this comment (#243 (comment)) with similar issue, but the issue where comment paced it not about it. Probably this is separate issue. Also in my reproduction repo includes in tsconfig already configured to match vue files, but it doesn't work anyway.

I can suggess the nature of this bug: rollup-plugin-vue generates virtual files (i.e. file.vue?some-plugin-metadata.ts) that doesn't exists on real filesystem, so typescript compiler at init phase doesn't know about this virtual files and cant add it to includes-list. Then plugin-typescript calls ts.getOutputFileNames function, where goes check for current file included in includes and compiler internal check fails, we see error in output. plugin-typescript2 does not call this function, so there is no error.

I don't think we're going to be able to resolve this one at present. The nature of the typescript plugin here is that it has to know about all files. You might have to go with a different typescript plugin that doesn't use the same BuilderProgram approach that ours does.

@spaceemotion we don't offer support here, and typescript2 is not a plugin in this repo.

Hey folks. This issue hasn't received any traction for 60 days, so we're going to close this for housekeeping. If this is still an ongoing issue, please do consider contributing a Pull Request to resolve it. Further discussion is always welcome even with the issue closed. If anything actionable is posted in the comments, we'll consider reopening it. ⓘ

The cause of the problem is that the plugin simply doesn't pick up the file names used (generated) by rollup-plugin-vue.

See this repository for a simple example with some debugging output. The file src/components/hello/Hello.vue?vue&type=script&lang.ts is never transformed by the plugin. Thus rollup tries to process it in its final stage, which fails, of course.

src/components/hello/Hello.vue?vue&type=script&lang.ts (13:16)
11:     
12:     setup(props) {
13:         let temp: string | null = null; 
                    ^
14:         return {};
15:     },
Error: Unexpected token (Note that you need plugins to import files that are not JavaScript)

原因是插件根本没有选

I also encountered this situation, will solve later

问题的原因是插件根本没有选择 rollup-plugin-vue 使用（生成）的文件名。

有关一些调试输出的简单示例，请参阅此存储库。该文件src/components/hello/Hello.vue?vue&type=script&lang.ts永远不会被插件转换。因此， rollup 试图在最后阶段处理它，当然，这失败了。

src/components/hello/Hello.vue?vue&type=script&lang.ts (13:16)
11:     
12:     setup(props) {
13:         let temp: string | null = null; 
                    ^
14:         return {};
15:     },
Error: Unexpected token (Note that you need plugins to import files that are not JavaScript)

Did you solve it? I'm just like you right now, looking everywhere

I've used another typescript plugin instead of this "official" one (as mentioned above).

I worked late that night, and I was using another TypeScript

rollup-plugin-typescript2
Is this!
