Drush + Cygwin PHP致命错误

Question

I have had to re-install / update Cygwin on Windows 8.1, and I have some how broken Drush on my Drupal 7 sites.

Previously I followed this guide Here So I have tried to do a clean install of drush, and noticed that you can now install drush via pear.

pear channel-discover pear.drush.org
pear install drush/drush

So in my home directory :

$ drush --version
 Drush Version   :  6.2.0

That seems to work, but when I go into my directory where my Drupal web site is, I am getting PHP fatal errors, it is like the PATH or something is broken when I run drush from there :

$ cd /cygdrive/c/websites/www.mywebsite.com
$ drush
require_once(c:/websites/www.mywebsite.com/modules/system/system.module): failed to open stream: No such file or directory drupal.inc:21           [warning]
PHP Fatal error:  require_once(): Failed opening required 'c:/websites/www.mywebsite.com/modules/system/system.module' (include_path='.:/usr/share/pear') in /usr/share/pear/drush/includes/drupal.inc on line 21
require_once(c:/websites/www.mywebsite.com/modules/system/system.module): failed to open stream: No such file or directory drupal.inc:21           [warning]

My Current set up is :

• Windows 8.1
• Cygwin
• Drupal 7
• For PHP I am using WAMP, but PHP is working in Cygwin

.

Answer 1

When using Cygwin's version of PHP, the "require" statement does not recognize path names which start with a drive letter. Thus require 'C:\path-to-file' will generally fail. Internally, it sees the 'C:' as a relative path and appends it to the default directory rather than treating it as an absolute path.

If you rewrite the require statements to use __DIR__, then things usually work.

require __DIR__ . '/modules/system/system.module';
