Troubleshooting common issues

Downloads fail in Windows

If you're using code or commands, e.g. the chromedriver:update one, that download files and those keep failing with a message like the following:

File ... download failed: SSL certificate problem: unable to get local issuer certificate

It's likely the issue originates from PHP not having access to the system certificate store.

You can fix this by downloading the certificates file and setting the curl.cainfo and openssl.cafile PHP configuration options to point to it:

curl.cainfo = "C:\path\to\cacert.pem"
openssl.cafile = "C:\path\to\cacert.pem"
