How to fix ““Uncaught SyntaxError: Cannot use import statement outside a module” when importing ECMAScript 6”?
To Solve the Uncaught SyntaxError Cannot Use Import Statement Outside a Module Error, simply add type=”module”, as shown below. If you receive ReferenceError: require cannot be defined, you will need to use the import syntax rather than requiring. They can’t be mixed and matched, so you will need to choose one or use a bundler to combine them.
Solution 1: Simply add type=”module” to the script tag
Simply add type=”module” to the script tag, as shown below.
<script type="module" src="milsymbol-2.0.0/src/milsymbol.js"></script>
Solution 2: Add “type:module” to your package.json
Simply add “type” and “module” to the package.json
{
// ...
"type": "module",
// ...
}
If you receive ReferenceError: require cannot be defined, you will need to use the import syntax rather than requiring. They can’t be mixed and matched, so you will need to choose one or use a bundler to combine them.
Solution 3: Change this line
This line is the reason I am now in this mess. It was before like this
<script src="../src/main.js"></script>
After changing the settings, it worked perfectly.
<script type="module" src="../src/main.js"></script>
Solution 4: Use the .mjs
extension in your files
Use ECMAScript 6 modules via the browser by using the.js extension. In your files, add type = "module"
to the script tag.
Use ECMAScript 6 modules in a Node.js environment by adding the .mjs
extension to your files. Then, run this command to execute the file.
node --experimental-modules filename.mjs
Solution 5: Use require instead of import to solve the Uncaught SyntaxError
This problem was solved by changing “import” from”require”.
// import { parse } from 'node-html-parser';
parse = require('node-html-parser');
