npm install failing with transitive dependency error

[jeblackburn]

Hello,

NPM install is failing for me with an error about version conflicts through your dependency on material-ui-chip-input.

npm ERR! Could not resolve dependency:
npm ERR! peer @material-ui/core@"^1.0.0 || ^3.1.0" from [email protected]
npm ERR! node_modules/material-ui-chip-input
npm ERR!   peer material-ui-chip-input@">=1" from [email protected]
npm ERR!   node_modules/material-ui-formik-components
npm ERR!     material-ui-formik-components@"0.7.0" from the root project

Relevant content of my package.json:

    "@material-ui/core": "^4.11.3",
    "@material-ui/icons": "^4.11.2",
    "@material-ui/lab": "*",
    "formik": "^2.2.9",
    "material-ui-formik-components": "0.7.0",

I don't understand why material-ui-chip-input is being drawn into the conversation; I thought it was optional.

Thanks.
