问题描述

我有带有 mongodb 的 debian 开发服务器；php 5.4 和 pecl mongodb 驱动程序 v1.4.3.我尝试使用 PHP Cli 创建简单的连接并出现异常:

I have debian dev server with stock mongodb; php 5.4 and pecl mongodb drivers v1.4.3. I tried to create simple conntection using PHP Cli and got exception:

php -r "MongoLog::setLevel(MongoLog::ALL); MongoLog::setModule(MongoLog::ALL); new MongoClient('mongodb://127.0.0.1:27017', array());"

输出如下:

我找到了解决方法 - 将驱动程序版本降级到 1.3.6；但这不是解决方案.

I have found workaround - is downgrade dirver version to 1.3.6; but it is not a solution.

推荐答案

今天遇到同样的问题，降级到 1.3.6 版本的 pecl 中的 mongo 驱动程序对我有用"... 系统:Debian Squeeze这可以为您完成工作:

Had the same problem today, downgraded to the 1.3.6 version of mongo driver in pecl "worked" for me... System: Debian Squeeze This does the job for you:

pecl uninstall mongo
pecl install mongo-1.3.6
