title: ESM packages need to be imported
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
Packages in node_modules that are published as EcmaScript Module, need to be `import`ed via `import ... from 'package'` or `import('package')`.
|
|
|
|
You get this error when using a different way to reference the package, e. g. `require()`.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
1. Use `import` or `import()` to reference the package instead. (Recommended)
|
|
|
|
2. If you are already using `import`, make sure that this is not changed by a transpiler, e. g. TypeScript or Babel.
|
|
|
|
3. Switch to loose mode (`experimental.esmExternals: 'loose'`), which tries to automatically correct this error.
