Pear: "go-pear.phar" Does Not Have a Signature
Thankfully, after searching around – I found the solution from a blogger named Latyr, who blogs in French. Since I speak French, I thought I should offer his solution in English. I expanded it into a few steps, for those that aren’t familiar with WAMP and PHP.
1) Locate the “php.ini” file. In my case, I found it at this path:
Don’t use the WAMP system tray icon to edit this file. It didn’t work when I tried – you have to manually locate it.
2) Find the following line, in bold:
;phar.require_hash = On
3) Uncomment the “;phar.require_hash = On” line by removing the semi-colon.
4) Change “On” to “Off”.
phar.require_hash = Off
5) Save the file.
After I performed those steps, “go-pear.bat” began working normally again.
In case you’re wondering about the phar.require_hash option we just disabled, here’s the php.net description:
This option will force all opened Phar archives to contain some kind of signature (currently MD5, SHA1, SHA256 and SHA512 are supported), and will refuse to process any Phar archive that does not contain a signature.
The solution offered here was made possible by Latyr’s original blog post, entitled “Bug dans PHP5.3.0 Pear.bat”.
