Cannot install deep peer dependencies

[mayorovp]

MCVE:

npm init
npx install-peerdeps @typespec/html-program-viewer

Expected result

@types/react package is installed

Actual result

Only @typespec/html-program-viewer and @typespec/compiler are installed

[ljharb]

why would you expect @types/react to be installed? https://unpkg.com/browse/@typespec/[email protected]/package.json lists @typespec/compiler as the only peer dep.

Then that's probably yarn being broken, as it often is. If you're using PnP, try disabling that.

That's not yarn being broken, that's you forgot about transitive dependencies вт, 24 сент. 2024 г., 01:08 Jordan Harband ***@***.***>:

DT packages should only be dev deps ever, and this tool isn’t intended to install transitive peer deps afaik. It’s each package’s responsibility to explicitly list all the peer deps its dependencies, and not let them be implicit.
