MongoDB异常:服务器报告的连线版本为0，但libmongoc的版本至少需要3 [英] MongoDB Exception: Server reports wire version 0, but version of libmongoc requires at least 3

问题描述

Fatal error: Uncaught MongoDB\Driver\Exception\ConnectionException: Server at localhost:27017 reports wire version 0, but this version of libmongoc requires at least 3 (MongoDB 3.0)

我有PHP 7.0.13，MAMP和MongoDB.已安装用于PHP的MongoDB扩展.

I have PHP 7.0.13, MAMP and MongoDB. The MongoDB extension for PHP has been installed.

我有以下内容:

<?php

ini_set('display_errors', 'On');
require 'vendor/autoload.php';
var_dump(extension_loaded('mongodb'));
echo phpversion('mongodb')."\n";

$m = new MongoDB\Driver\Manager("mongodb://localhost:27017");

// Query Class
$query = new MongoDB\Driver\Query(array('age' => 30));

// Output of the executeQuery will be object of MongoDB\Driver\Cursor class
$cursor = $m->executeQuery('testDb.testColl', $query);

// Convert cursor to Array and print result
print_r($cursor->toArray());

?>

在这种情况下，线"指的是什么?有人对此问题有解决方案吗?

What does 'wire' refer to in this context, and does anyone have a solution for this problem?

推荐答案

我在Linux Mint 19上遇到了问题(认为Ubuntu 18+可能有同样的问题):

I have got the problem on Linux Mint 19 (think that Ubuntu 18+ can have the same problem):

IP:27017的服务器报告的有线版本为2，但是此版本的libmongoc至少需要3(MongoDB 3.0)

Server at IP:27017 reports wire version 2, but this version of libmongoc requires at least 3 (MongoDB 3.0)

如消息所示-服务器驱动程序版本与我的驱动程序版本不同. 发生这种情况是因为我使用以下命令安装了php mongo驱动程序:

As the message says - server driver version and mine one are different. This happened because I installed php mongo driver with the command:

sudo apt-get install php7.2-mongodb

解决方案是要完全卸载php mongo驱动程序:

The SOLUTION was to completely uninstall php mongo driver:

sudo apt-get remove --auto-remove php-mongodb

，然后从 Pecl mongodb php扩展名安装:

and then install php-mongodb from Pecl mongodb php extension:

sudo pecl install mongodb-1.4.4

(如果遇到错误pecl: command not found，只需安装PEAR软件包即可使用pecl安装程序.sudo apt-get update && sudo apt-get install php-pear )

(If you bump into error pecl: command not found, just install PEAR package in order to use pecl installer. sudo apt-get update && sudo apt-get install php-pear)

之后，将下一行添加到您的php.ini文件中:

After that add the next line to your php.ini file:

extension=mongodb.so

别忘了重新加载Web服务器:

Don't forget to reload the web server:

sudo systemctl reload apache2

就是这样.一切都会正常！

That's it. Everything should work!
