Syntax error: invalid regular expressions

[codytooker]

When running the generator I get the following error in the console leading to not being able to run the generator.

 ERROR  SyntaxError: Invalid regular expression: /(?<fileName>[^(\s]+):[0-9]+:[0-9]+/: Invalid group

Seems to be related to a recent PR
#12

Can I get a rundown of what options were chosen when creating the Vue project initially as well as what options were chosen when adding the plugin? Are you using just the CLI or are you using the UI?

This will help me troubleshoot where this may be going wrong as I haven't been able to reproduce this yet with 3 different manual tests.

[jandever]

I got the same error through the CLI as with the UI. Tried multiple different options (also all default) creating the Vue project and adding the plugin. Each time the error occurs.

Can I see a list of global packages installed? npm list -g --depth=0
Also, OS version

What version of node are you running?

side note: realizing we need a standard 'submit issue` list of questions to ask when someone submits an issue.

[jandever]

node --version
v8.9.1

updating nodejs solved the problem

[codytooker]

I can't currently get a rundown of global packages as I'm away from the computer but basically the same as above in installing from UI and CLI and trying multiple packages.

I'm guessing it comes this line

vue-cli-plugin-nativescript-vue/generator/index.js

Line 908 in 80cc51b

let { fileName } = /(?<fileName>[^(\s]+):[0-9]+:[0-9]+/.exec(callSite).groups;

. From my knowledge only ES2018 has the ability to do look behind regular expressions.

[jawa-the-hutt]

Ok...i was able to reproduce on node version 8 regardless of the version of npm.

[jawa-the-hutt]

So, I had just commented that I was able to reproduce on any version of Node 8 and saw a couple of notifications come in at the same time with updates from @jandever and @codytooker. However, now the issue doesn't show those comments.

Looks like the fix is to be on node 10.x or above as node 8 doesn't support the look behinds. I'm going to leave this issue open and see if I can come up with a regular expression that will work on node 8, 10 and 12.

May not be possible, but at least the temporary workaround is to upgrade to at least 10.x.

Should be addressed in #19
