## Updates from Percy
### 2026-09-24 23:42 UTC: resolved
Status: Fix released with percy/cli v1.32.11
Since 20:48 UTC on September 24, npm install @percy/cli fails with:
 npm ERR! code EUNSUPPORTEDPROTOCOL
 npm ERR! Unsupported URL Type "patch:": patch:got@npm%3A11.8.2#...
With npm 10 and later, the install can fail with no error message.
Cause: A third-party package that the Percy CLI depends on, @yarnpkg/core, published version 4.9.2 with a dependency format that npm can't install. Percy's services are not affected; only new CLI installs are.
Fix: We have released a patch version of percy/cli v1.32.11 and now @latest should install correctly
Workaround (for earlier percy cli versions if pinned): Add this to your project's root package.json:
 "overrides": {
 "@yarnpkg/core": "4.9.1"
 }
