Patching Git modules without version

Author: tim-elmerCreated Oct 22, 2023Updated Apr 13, 2026

I'm attempting to patch a package distributed via Git (Antora's default UI) that doesn't have a version number in its package.json. Not terribly surprisingly, patch-package isn't thrilled about this:

...\node_modules\patch-package\dist\makePatch.js:395
        throw e;
        ^

TypeError: Cannot read properties of undefined (reading 'replace')
    at Object.getPackageVersion (...\node_modules\patch-package\dist\getPackageVersion.js:6:51)
    at Object.makePatch (...\node_modules\patch-package\dist\makePatch.js:111:52)
    at ...\node_modules\patch-package\dist\index.js:72:25
    at Array.forEach (<anonymous>)
    at Object.<anonymous> (...\node_modules\patch-package\dist\index.js:71:22)
    at Module._compile (node:internal/modules/cjs/loader:1256:14)

    at Module._load (node:internal/modules/cjs/loader:960:12)
    at Module.require (node:internal/modules/cjs/loader:1143:19)

Node.js v18.18.0

I've attempted explicitly installing the package by commit ID to no avail. Am I missing something, or is this currently not supported?

If not, I'd like to request that support be added. I'd expect patch-package to patch against the current "version" (in this case, the provided or default Git branch) if no version information is available.
