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" }
