PHP 7 : MongoDB Driver issue

Question

我在尝试安装 MongoDB PHP 库时遇到错误:

$ composer require "mongodb/mongodb=^1.0.0"

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0

当我执行 phpinfo() 时，我可以看到以下内容:

mongodb

mongodb support enabled
mongodb version 1.2.1
mongodb stability   stable
libmongoc version   1.5.0
libbson version 1.5.0

当我执行 locate mongodb.so 时，这里是我的 mongodb.so 文件所在的位置:

/usr/lib/php/20151012/mongodb.so

我注意到，这是 20-mongodb.ini 文件所在的路径:

/etc/php/7.0/apache2/conf.d

此外，sudo pecl mongodb install 返回以下内容:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0

sudo pecl info mongodb 返回:

我在 Google 上搜索了几个小时，但还是一无所获。谢谢。

是的，有很好的答案。这是我在 php7.1 中安装 mongo 所做的。我使用的是 ubuntu16.04 64 位:

sudo aptitude install -y php7.1-dev pkg-config
sudo -H pecl channel-update pecl.php.net
sudo aptitude install -y libcurl4-openssl-dev pkg-config libssl-dev libsslcommon2-dev
sudo pecl install mongodb
echo 'extension=mongodb.so' | sudo tee /etc/php/7.1/fpm/conf.d/30-mongodb.ini
echo 'extension=mongodb.so' | sudo tee /etc/php/7.1/cli/conf.d/30-mongodb.ini
sudo systemctl restart php7.1-fpm.service

这一切都是为了 nginx。如果您使用的是 apache，请添加:

echo 'extension=mongodb.so' | sudo tee /etc/php/7.1/apache2/conf.d/30-mongodb.ini

还有一个。如果您在使用 mongo 时继续出现错误。类似的东西:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303/mongodb.so' - libssl.so.1.0.2: cannot open shared object file: No such file or directory in Unknown on line 0

不要绝望，运行以下命令:

sudo pecl uninstall mongodb
sudo pecl install mongodb
