Post install script failed

[Deleted user]

I'm using VS Code 1.20.1, When I create a new extension project using yo code, the post install script for vscode module produces the following output:

Error installing vscode.d.ts: Missing VSCode engine declaration in package.json.

In the package.json of the extension project:

"engines": {
        "vscode": "^1.17.0"
}

@SABIH-YUSSUF can you attach the project as zip?
