Interesting. Although the package only claims support for React 18, the package does seem to work fine with React 19 and our default installer, bun doesn't seem to error out with this peer dependency issue.

Is there a reason why you're using npm to install? What platform are you on?

[masenf]

I filed an issue in the upstream package nkbt/react-debounce-input#161 not dissimilar to previous issues requesting the same for React 17 and 18 over the years. Hopefully we can get a new version released which doesn't have this issue. In the mean time, if you're able to install deps with bun then things should still be working.

in China, reflex use bun with registry = "https://r.cnpmjs.org", this will raise some errors:

bun install v1.2.0 (b0c5a765)

then will fallback to use npm.
my system is windows.

I'm a user from China. I encountered the same problem when running the Reflex project using npm in the Ubuntu 24.04 environment of Windows 11 WSL2.

Besides, I'll explain why npm should be used：
Although I set up a network proxy in WSL2, after a certain version of 0.6.6, when running the Reflex project, the default Bun compilation step would get stuck for dozens of minutes. Then I tried npm and added the following configurations:
REFLEX_USE_NPM = 1
NPM_CONFIG_REGISTRY = http://registry.npmmirror.com/
However, Reflex still used Bun (perhaps because my system is Ubuntu instead of Windows?). Later, I solved the problem with the help of Windsurf. It modified the get_install_package_manager method in the utils/prerequisites.py file and gave priority to the setting of environment.REFLEX_USE_NPM.
Since then, every time I upgrade the version of Reflex, I have to repeatedly modify the get_install_package_manager method to use npm.

Yes, I encountered the same issue while upgrading to 0.7.1. I am using Windows 11 and NPM. Could you please provide a patch for 0.7.1 to resolve this problem? For now, I have no choice but to revert back to 0.7.0.
