Tslint: `no-unsafe-any` with tsx throwing error

[tyv]

Hi! Can't understand why.

CLI:

tslint -c tslint.json --type-check --project tsconfig.json src/app.tsx

tsconfig.json:

{
  "compilerOptions": {
    "target": "es5", 
    "module": "commonjs",
    "lib": [
      "dom",
      "es2015"
    ],                                        
    "jsx": "react",                           
    "declaration": true,                      
    "sourceMap": true,                        
    "experimentalDecorators": true        
  }
}

TypeScript code being linted

import * as React from 'react';

export class App extends React.Component<{}, {}> {
    public render(): JSX.Element {
        return <span/>;
    }
}

with tslint.json configuration:

{
    "rules": {
        "no-unsafe-any": true
    }
}

Actual behavior

Error

ERROR: app.tsx[5, 17]: Unsafe use of expression of type 'any'.

Expected behavior

Do you have @types/react installed? Are there any tsc errors when you compile your project with --noImplicitAny?

I have the same problem

Can you try to repro this with the latest TSLint? We've had various refactorings occur since 5.5.0.

It's still reproducible (in my case)

This was fixed by #3699. 🎉

For anyone that finds this in the future. I was struggling with this for over an hour while configuring eslint. After adding the types with yarn add -D @types/react @types/react-dom I was still getting an error on the return statement. This was fixed by simply reloading/restarting vscode. Save yourself some time and use F1 -> Reload Window.
