VSCode Error - SyntaxError: Named export 'isIdentifier' not found.

Describe the bug

Currently seeing

SyntaxError: Named export 'isIdentifier' not found. The requested module '@babel/types' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@babel/types';
const { isVariableDeclarator, isIdentifier, isTemplateLiteral, isImportDefaultSpecifier, isImportSpecifier } = pkg;

In all Svelte files when using a custom plugin.

To be clear, the plugin works 100% as expected. The only problem here is the error message in VSCode.

To Reproduce Steps to reproduce the behavior:

Clone repo https://github.com/stolinski/sk-gquery-reporduction npm install Open in vscode, look at any .svelte file.

Expected behavior

Plugin would work and no errors on loading.

Screenshots If applicable, add screenshots to help explain your problem.

System (please complete the following information):

• OS: MacOS
• IDE: VSCode
• Plugin/Package:“Svelte for VSCode”

Additional context

There doesn’t seem to be any issue functionally but the error does clog our error log and causes issues trying to find TS errors.

As mentioned in the discord. This is a problem with the node.js version vscode bundled. It’s 14.16.0 in vscode 1.61.2. Using the svelte.language-server.runtime config should make the error goes away. It works on my machine.

From node.js API docs nodejs 14.16.0 uses cjs-module-lexer 1.0.0. While 14.17.0 uses cjs-module-lexer 1.1.1. And from the change log. The babel issue seems to be fixed in 1.1.1. So this issue should be resolved the next time vscode bumps the node.js version. (probably depends on the electron version they’re using though)

I am going to close this since I think this is fixed and I can’t reproduce this anymore. Feel feel to reopen if you can still reproduce this.
