Running on Windows

[dvossos]

I have successfully implemented a project that functions flawlessly on macOS and Linux operating systems. However, I encountered an unexpected issue when attempting to run the same project on Windows. Specifically, after transferring and installing the project using Git, I noticed an unusual behavior.

In detail, the program successfully crawls all the $startUrls, but it exits normally without entering the parse method or any other user-defined parse method. Consequently, I am unable to proceed with the desired functionality.

I would greatly appreciate any assistance or guidance in resolving this issue. It is possible that I might be overlooking something crucial. Thank you in advance for your help.

Upon debugging and testing, I discovered that the issue was with the Downloader class not receiving a response, resulting in it never entering the onResponseReceived method. The error message indicated that the guzzle http client request was throwing the following exception:

cURL error 60: SSL certificate: unable to get local issuer certificate

In order to resolve this, I followed these steps:

1. Downloaded the cacert file from https://curl.haxx.se/docs/caextract.html.

2. Placed the downloaded cert.pem file in a suitable directory.

3. Edited the php.ini file with the following lines:

   curl.cainfo = "C:\Program Files\Common Files\SSL\cert.pem"
   openssl.cafile = "C:\Program Files\Common Files\SSL\cert.pem"
   

After making these changes, the issue was resolved and everything started working as expected.
