Can't run builds or tests

[Knogobert]

Nice playground! Definitely good inspiration on how to write tests.

But unfortunately I think you're missing a package or something, because when I run cd done && yarn && yarn serve.

I get this:

ERROR  Failed to compile with 1 errors                                                                                                                                 2:17:46 PM

I tried installing @babel/compat-data to no avail.

Happy hunting!

Hello, let me know which version of vue-cli and node do you have locally by running the following command:

vue -V && node -v

Please make sure if you have at least 4.X vue-cli version. Maybe I will need to update requirements in README. If you have older vue-cli od don't have it, please install or update it by following this instruction

After checking version can you tell me that you are able to create base new project by vue-cli with this command:

vue create yourTempProjectName

Let me know if it's created successfully or not. Thanks for checking my repo!

I didn't have @vue/cli installed globally on this computer before. Now though, after installing it, I have:

vue/cli: 4.3.1
node: v14.2.0

And unfortunately I could successfully create and serve a basic app through vue-cli.

Sorry for a late response but didn't spot notify about the message. I've dug a bit through your error and found out some hints.

This issue babel/babel#11439 which recommends updating babel packages but I will just update @vue/cli in the repo to the latest version and release. They updated babel there and it should be fine there.

Also, using node v13 and v14 - which was your case - can cause problems during using older vue/cli like babel/babel#11491 here but we will see after my merge with an update.

But wasn't sure why I can't reproduce this problem on my local when having the same setup. Maybe I have some globally installed dependencies and works well.

Anyway to summarize, after release tries these steps:

1. fetch new changes
2. delete node_module from a done directory and install dependencies again

And finally, try to run an app again. Hope it will lead us somewhere.

Ok, release is out.

@Knogobert when you will have some time can you give feedback about your issue? I will be thankful

[Knogobert]

I got it running on my other computer with

@vue/cli 4.0.5
node: v13.7.0

it also kept working when upgrading step by step to

@vue/cli 4.4.6

and then also kept working with

node: v14.6.0

So I'm closing the issue then, thanks!!
