tsc fails with many "Cannot find module '../../../../material-ui/src/....'" errors

[Philipp91]

• The issue is present in the latest alpha release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Two example errors:

node_modules/@material-ui/lab/internal/svg-icons/Calendar.d.ts:1:32 - error TS2307: Cannot find module '../../../../material-ui/src/OverridableComponent' or its corresponding type declarations.

1 declare const _default: import("../../../../material-ui/src/OverridableComponent").OverridableComponent<import("../../../../material-ui/src").SvgIconTypeMap<{}, "svg">>;
                                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

node_modules/@material-ui/lab/internal/svg-icons/Pen.d.ts:1:32 - error TS2307: Cannot find module '../../../../material-ui/src/OverridableComponent' or its corresponding type declarations.

1 declare const _default: import("../../../../material-ui/src/OverridableComponent").OverridableComponent<import("../../../../material-ui/src").SvgIconTypeMap<{}, "svg">>;
                                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Expected Behavior 🤔

No error. Though note that this only affects the .d.ts file, so the application compiles and runs just fine with webpack.

Steps to Reproduce 🕹

Compile the project with tsc. I couldn't find a way to call tsc on codesandbox.io.

Context 🔦

The code pushed to NPM indeed contains that path:

npm pack @material-ui/[email protected]
tar --extract --file=material-ui-lab-5.0.0-alpha.22.tgz package/internal/svg-icons/Pen.d.ts -O
declare const _default: import("../../../../material-ui/src/OverridableComponent").OverridableComponent<import("../../../../material-ui/src").SvgIconTypeMap<{}, "svg">>;
/**
 * @ignore - internal component.
 */
export default _default;

When unpacked, ../../../../material-ui resolves to ./node_modules/material-ui, which indeed does not exist. I guess there's some config where material-ui needs to be replaced with @material-ui/core. Or maybe this is applied when packaging the library even though it shouldn't be? Or maybe this needs to do something smarter than just copy?

This might be happening because I'm doing this:

import PenIcon from '@material-ui/lab/internal/svg-icons/Pen';

Thanks, sorry for not finding it (maybe because it reported the same issue for material-ui-styles instead of the core package?).
