Error: spawnSync /bin/sh ENOBUFS

I encountered Error: spawnSync /bin/sh ENOBUFS error when executing code-complexity. This is the error output.

node:internal/errors:932
  const err = new Error(message);
              ^
Error: Command failed: code-complexity . --since=2022-08-08 --format=json

It looks like the buffer size is not enough when executing git log. Based on the assumption, this error can happen if the output of git log is too large.

Hi there,

Sorry for the delay, I released a fix in an alpha version for the incoming v5. You can try it out here like this: npx code-complexity@alpha . --filter "**/*.ts" --sort=score -cs halstead
