Command failed with exit code 1. (checkExecSyncError)

[osrl]

Here is the log I get when I try to run yarn install, yarn add or node ./node_modules/postinstall-postinstall/run.js:

I've tried to debug this and I've found out that spawnSync inside checkExecSyncError returns an error. This causes checkExecSyncError to return an error also. Workaround is replacing execSync with exec.

error ****/node_modules/postinstall-postinstall: Command failed.
