Puppeteer: Could not find volume path in {value}
The macOS DMG attach result does not contain a volume mount path.
The macOS DMG attach result does not contain a volume mount path.
Error message
Could not find volume path in {value}
{value} is replaced by the value shown in your error message.
How this error happens
On macOS, the DMG attach output did not contain the mounted volume path expected by the installer. An attach failure or incompatible output can cause this.
The command demonstrates the installation workflow; it only fails when the archive or environment has the condition described above.
npx puppeteer browsers install
How to fix
Check the extraction or mount error first, ensure there is enough disk space, and retry package-managed installation into a separate writable cache.
PUPPETEER_CACHE_DIR=/absolute/path/new-browser-cache \
npx puppeteer browsers install
Things to keep in mind
Use the same cache location when launching. If a mirror supplied the wrong file, restore the trusted browser archive source before retrying. Do not delete a broad cache or unmount an unrelated volume.
