I have npm install-- save fs
several times, and I have succeeded, but I still report such an error
npm run dev
.
This dependency was not found:
* fs in ./node_modules/clone-stats/index.js, ./node_modules/convert-source-map/index.js and 6 others
To install it, you can run: npm install --save fs
> Listening at http://localhost:8080
this is why
it is useless for me to use root permissions to npm install fs
.
