Error: Debug Failure. Unhandled SyntaxKind: ImportClause.

I tied to run the command using npx but I get the following error:

❯ npx -p typescript -p cjstoesm cjstoesm ./src/lib
Need to install the following packages:
  typescript@5.0.4
  cjstoesm@2.1.2
Ok to proceed? (y)

Seems like TypeScript is broken somehow but I don't understand why this happens. Any clues?

[sleeyax]

Never mind, I fixed it by explicitly specifying the typescript version that is specified in this project's package.json: npx -p typescript@4.7.3 -p cjstoesm cjstoesm ./src/lib. I wish this was documented in the README though.

I'm experiencing this same issue but setting the TS version isn't helping. May create a new issue if I can't figure it out.

With TypeScript 4.9.5, I am getting the following warning:

DeprecationWarning: 'isTypeAssertion' has been deprecated since v4.0.0. Use `isTypeAssertionExpression` instead.
DeprecationWarning: 'createImportDeclaration' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.
DeprecationWarning: 'createExportAssignment' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.

They seem related to the ImportClause issue above.

Can we reopen this issue or create a new one as it seems TypeScript 5 support is not 100% here?

Might be late for you, but for others for future reference: make sure you install cjstoesm in your project directory with typescript@4. If you install it globally, then make sure that typescript globally is also v4.

Personally, I have only been able to get this working using:

 npx -p typescript@4.7.3 -p cjstoesm cjstoesm file.js

Processing my whole folder hierarchy was also challenging (struggled with this, so this is what I ended up with:

 find src -type d | xargs -I {} npx  -p typescript@4.7.3 -p cjstoesm cjstoesm {}
