instaling quiime 2 studio - error

After reviewing your logs, I think I found the source of the error. It looks like you have some conflicting dependencies for the packages that are being installed. See below:

npm ERR! While resolving: q2studio@2021.4.0
npm ERR! Found: react@15.7.0
npm ERR! node_modules/react
npm ERR! react@"^15.0.1" from the root project

.......

npm ERR! peer react@"^16.3.0" from redux-devtools-dock-monitor@1.2.0
npm ERR! node_modules/redux-devtools-dock-monitor
npm ERR! redux-devtools-dock-monitor@"^1.1.1" from the root project

I recommend attempting to change the versions of react and redux-devtools-dock-monitor to match those of the root project (react 15.0.1 and redux-devtools-dock-monitor 1.1.1 respectively).

You can do so using the following command:

npm install <package>@<version>

Please try using this to install the specified versions of those two packages, and let me know if you are successful!
