Polyclip-ts makes my program unable to run.

[ping-an-na]

I'm sorry I'm a rookie. I have updated to the latest version 7.2.0. Maybe I can't start Polyclip-ts because it is ts.
It's been bothering me all morning.Now I've taken care of him.But I hope I can help you.

Hi @ping-an-na. Are you saying you're having trouble with getting Turf to run? Is there an error message that you can see? Tell us some more information and we can try to help.

[ping-an-na]

Thank you. I hope we can work this out together.
Can you see the pictures I sent?
I repeated the question.
Probably because my project doesn't support TS.
My solution was to set the version to 7.1.0

I think what this error is saying is the Javascript in polyclip-ts is more modern that what your Vue application is expecting to see. Don't think it's typescript related.

To help troubleshoot, can you please answer some questions? Is this a new project? Or is it an old one? Are your vue and babel versions up to date? Would you mind sharing your package.json, tsconfig.json, and babel configuration?

If i were to try to reproduce this myself, is your app a fairly normal Vue 3 app?

[ping-an-na]

Thank you for your explanation, because I can't fully understand these error messages.

This is an old project. I'm using vue2.
It may not be easy for you to try to repeat the same effect.
I've invited you to join a project where you can clone it and take a look.

Thanks @ping-an-na. I will take a look. What command are you running when you see that error?

[ping-an-na]

npm run dev

[ping-an-na]

npm -v // 6.14.18
node -v // 14.14.0

Thanks @ping-an-na. I tried running the repo you shared, but ran into python errors.

Found this article which displays a very similar error, and suggests vue 2.7 should not have this problem: https://stackoverflow.com/a/67282216/3606644

Noticed you are using vue 2.6.10, so are you able to update to 2.7.16 and see if that helps?

[ping-an-na]

I updated VUE to version 2.7.16 and re-ran it, but there were still error messages and no changes.
I'll go and take a look at the article you sent.
My English is not very good. It will take me some time to understand.

[ping-an-na]

I don't understand what repo means, and I don't know why there are python error.
It could be your environment variable.
If npm and node versions are correct.
Just git clone, npm install, npm run dev.
I'm sorry I don't understand.

[smallsaucepan]

That's ok @ping-an-na.

repo = repository, https://github.com/ping-an-na/RuiFengDataScreen

Try this instead. Add the below transpileDependencies to your view.config.js:

module.exports = {
  transpileDependencies: [
    'polyclip-ts',
    'splaytree-ts'
  ],
  ...

This will tell babel to convert those two libraries to the older version of Javascript your project is using. Then npm run dev works:

This works even without having to upgrade vue as I suggested above.

Very, very, very good.
Yes, the problem was solved perfectly. Thank you very much for your help.
You were amazing. You were so professional. You've always been my idol.
I'm going to write an article about this. Maybe it can help someone else.
To express my feelings to you again. I wish you good health.

You're very welcome. Glad we were able to help! Thank you for offering to share the solution with other people.
