I installed polymer using the recommended syntax:
npm install -g polymer-cli#next
I created a polymer 2 element using the polymer init interface.
The issue I'm having is when I run polymer serve, I get the following error:
error: cli runtime exception: SyntaxError: Unexpected token [
error: SyntaxError: Unexpected token [

I tried uninstalling and reinstalling polymer, but getting the same issue. Any ideas??
Fixed my polymer client error.
It turns out the new version of polymer required node v6 or higher.. barely noticed that notice message when I installed.

I installed the Prettier plugin, installed Prettier with npm into my project, and when I try to use it to reformat something, it acts like there's a bug in Prettier. Here's what I get.

My guess is that you're running an old version of Node.js that doesn't support optional catch binding. What Node.js version is chosen in Settings | Languages & Frameworks | Node.js?
Hi I've been trying to use cheerio in my node library and found this error, i've narrowed it down to rollup not correctly getting the dependency other then that I'm at a loss
enviroment
OS macOS Mojave Version 10.14.3
Node v11.4.0
Rollup 1.6.0
Cheerio 1.0.0-rc.2
repo with error https://github.com/lukecollier/cheerio-rollup-problems
i get a stack trace with
util.js:307
throw new ERR_INVALID_ARG_TYPE('superCtor', 'Function', superCtor);
^
TypeError [ERR_INVALID_ARG_TYPE]: The "superCtor" argument must be of type Function. Received type undefined

when I look into the output javascript it seems that it's a rollup error not adding the right dependencies but I want to make sure I'm not missing something before opening a issue
I get an error while installing React-native, I have tried to search for an answer, but I can not find one.

I don't really get what is wrong...
It's related to an issue with gulp-sourcemaps recent deployment https://github.com/floridoo/gulp-sourcemaps/issues/238
A project maintainer says at the end of the thread that he'll get to it today and
For the time being lock your version down to 2.0.x or 1.7.x
To fix, add specific version in your package.json until the issue is fixed:
{
"devDependencies": {
"gulp-sourcemaps": "1.7.x"
}
}
Use npm shrinkwrap to prevent similar issues in the future.
This is caused by a recent change in gulp-sourcemaps. See bug here: https://github.com/floridoo/gulp-sourcemaps/issues/238
This is now fixed. Run npm install

I already reinstalled Polymer cli, but it returns allways the same error.
I found the solution!
I reinstalled node js and now I can run Polymer.
Maybe I had an unsuported version of node js.
I am trying to launch polyserve on my local development environment but it is not working. thought it might be due to node.js updated node but still getting this error.

According to my copy of polyserv, its package.json file says it needs the resolve module
https://www.npmjs.com/package/resolve
Your error is that it can't find it.
Is polyserve installed locally - run npm install
