Error when updated meteor from 1.8.1 to 1.8.3

I get this error when I try to run Meteor app

While building for web.browser:
node_modules/cssstyle/lib/properties.js:5029:9: Identifier ‘parse’ has
already been declared (5029:9)

While building for web.browser.legacy:
node_modules/cssstyle/lib/properties.js:5029:9: Identifier ‘parse’ has
already been declared (5029:9)

Please help

it seems not related to Meteor upgrade, can you check if you declare only one time the variable “parse” ?

cssstyle is not a dependency that I added in my project. Anyway I’ll check the source code of the library.

have you update @babel/runtime and meteor-node-stubs, how says

meteor npm install @babel/runtime@latest
meteor npm install meteor-node-stubs@next

I have the same problem, does anyone have a solution?

I did install these two things. Still not solved.

Same problem, trying to migrate an older app from 1.4.2 to 1.9…

Error trips when adding pwstrength-bootstrap plugin ( in /client/lib/plugins folder used for JS-JQuery plugins.

Maybe a jQuery related conflict?

Note: Updating the plugin to the newest version did not solve the error.

As @jithinks noted if you check the library source there’s a function repeated at line 5029:9 that was declared earlier at line 1644:

function parse(v) {
  if (String(v).toLowerCase() === 'auto') {
    return 'auto';

  if (String(v).toLowerCase() === 'inherit') {
    return 'inherit';

Why is this an error? Isn’t function overriding okay in JS?

I just started getting this today after updating an old project to latest meteor version.
Did anyone figure out what the solution is ?
