What could be causing my TypeScript project to only fail in VScode?

After taking a several-week break from my TypeScript-based open-source project, I have returned to fix a bug. However, when running the project in VScode, it suddenly fails and presents legitimate errors that need fixing. What's puzzling is why these errors are occurring now just in VScode, not through the command-line as well.

...project/node_modules/ts-node/src/index.ts:587
    return new TSError(diagnosticText, diagnosticCodes);
           ^
TSError: ⨯ Unable to compile TypeScript:
...project/src/bar.ts(361,27): error TS2532: Object is possibly 'undefined'.

While I acknowledge the error, how can I temporarily get it working again?

Answer №1

When it comes to vscode, the software will utilize its own built-in TypeScript version to verify the syntax of your .ts files or to execute tasks in vscode. In some cases, if the TypeScript version in your project differs from the one built into vscode, you may encounter issues that require resolution.

If you want to compel vscode to use the TypeScript version specific to your project, follow these steps: Access a .ts file within your vscode and locate the Typescript version displayed at the bottom right corner (often around 4.3.x). Click on it and adjust the settings to ensure that vscode utilizes the TypeScript version located in your node_modules directory.
