• node version: 11.10.1-1

• npm version: 6.8.0-1

  * ncu version: 2.15.0

The command ncu -u doesn't upgrade my package.json file.

ncu -u                                                    
Using /path/to/package.json
[..................] / :
 gatsby                  ^2.1.19  →  ^2.1.22 
 gatsby-image            ^2.0.30  →  ^2.0.31 
 gatsby-plugin-manifest  ^2.0.20  →  ^2.0.21

 gatsby-remark-images     ^3.0.5  →   ^3.0.6 
 react-spring             ^8.0.9  →  ^8.0.11 

It lacks the message package.json upgraded and indeed the package doesn't change at all.

Thanks for reporting. I will try this out when I am at my computer and see if I can reproduce.

I downgraded my ncu version in the meantime.
Not sure in was version it's breaking but I randomly downgraded to 2.11.0

@anonimoconiglio npm install -g [email protected]

Did it work if downgraded?

That's very odd. ncu -u is upgrading the package.json on my end.

I just upgraded to V3 (3.0.3) and now it works again!
