Answer 1

这已在 Magento 论坛上得到解答：http://www.magentocommerce.com/boards/viewthread/17358/

"...在 magento 安装的根目录中创建一个 tmp 目录..."

Answer 2

Magento 查看一些 $_ENV 和 $_SERVER 变量以找到合理的可写目录。它寻找 TMPDIR、TEMP、TMP、 8windir* 和 SystemRoot 变量找到一个。 （你可以在Zend_Cache_Backend::getTmpDir看到它）。

所以有一些步骤要检查...

1. 在 phpinfo 验证您的 apache/nginx 用户，并检查该用户是否有权访问 var/cache 目录；
2. 如果您使用 apache 并启用了 mod_env，您可以通过在 .htaccess 中添加以下行来手动设置您的 tmp 目录：

SetEnv TMP /path/to/other/tmp/dir

3 .如果你使用 nginx，你可以尝试添加这样的参数：

fastcgi_param TMP /path/to/other/tmp/dir
