typescript@next (and 2.9.x) outputs node_modules relative path to imports

[felixknox]

Related to issue #24599 , where @mhegazy specifically asks to create a separate ticket with more information when using latest typescript@next (^3.0.0-dev.20180630")

Imports get's node_modules added, which breaks Library conventions.

It's easy to replicate.
import ex. a library like @material-ui, which you have as a dependency.

Using a tsconfig file like

"compilerOptions": {
    "baseUrl": "./",
    "rootDir": "src",
    "outDir": "dist",

    "declaration": true,

    "module": "commonjs",
    "target": "es5",
    "lib": [ "es6", "dom" ],
    "sourceMap": true,
    "moduleResolution": "node",

    "jsx": "react",
    "forceConsistentCasingInFileNames": true,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "noImplicitAny": false,
    "strictNullChecks": true,
    "suppressImplicitAnyIndexErrors": true,
    "noUnusedLocals": false,
  },
  "exclude": [
    "node_modules"
  ]

Will take a .tsx file like:

import * as React from 'react';
import { WithStyles } from '@material-ui/core';
import { withStyles } from '@material-ui/core/styles';
import formBasicsStyles from "./../../../theme/formBasics";

interface IFileUploadProps extends WithStyles{

}

export const FileUpload = withStyles(formBasicsStyles)(
    class extends React.Component<IFileUploadProps> {
        constructor(props: IFileUploadProps){
            super(props);
        }

        public render() {
            const { classes } = this.props;

            return (
                <div>

                </div>
            );
        }
    }
);

And output a d.ts file like:

import * as React from 'react';
import { WithStyles } from '@material-ui/core';
interface IFileUploadProps extends WithStyles {
}
export declare const FileUpload: React.ComponentType<import("node_modules/@material-ui/core").Overwrite<IFileUploadProps, import("node_modules/@material-ui/core/styles/withStyles").StyledComponentProps<string>>>;
export {};

In the output d.ts file one would
expect: import("@material-ui....
but result is: import("node_modules/@material-ui...

Hope information is sufficient.

#25186

[mhegazy]

looks like a possible duplicate of #25338

@mhegazy I'd wager it's much more likely another expression of #25186. (which @Andy-MS has a fix open for)

Should be fixed by #25364, please try again with typescript@next.
