DTK0050: Integration Install Failed

Message

Failed to install {packages}.

Cause

Vite DevTools ships as a dependency-light shell: the built-in integrations (Rolldown, Vite, Vitest, Oxc) are advertised as discovery launchers in the dock rail, and their packages are installed on demand the first time you click Install on a launcher. This diagnostic is thrown when that install — whose command is resolved by package-manager-detector for the project's detected package manager and run as a tracked terminal session — fails, for example due to network restrictions, a read-only file system, or a package manager error.

Example

Clicking Install @vitejs/devtools-rolldown in the dock while offline, so the package manager cannot reach the registry.

Fix

Install the package(s) manually with your package manager, then restart the dev server so DevTools picks them up:

pnpm add -D @vitejs/devtools-rolldown
# or: npm i -D @vitejs/devtools-rolldown
# or: yarn add -D @vitejs/devtools-rolldown

Source

• packages/kit/src/node/create-install-launcher.ts — the launcher runs the install as a tracked terminal session and throws this when it exits non-zero.
