php - 无法使用 Composer 安装 PHP 扩展 mongo

Question

如何在 Mac 机器上使用 Composer 安装 PHP 扩展 Mongo？我使用以下命令通过 Composer 安装 PHP 扩展。

composer install --prefer-source

我遇到了以下异常。

vagrant@vagrant:/var/www$ composer install --prefer-source
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for doctrine/mongodb 1.4.x-dev -> satisfiable by doctrine/mongodb[1.4.x-dev].
    - doctrine/mongodb 1.4.x-dev requires ext-mongo ^1.5 -> the requested PHP extension mongo is missing from your system.
  Problem 2
    - Installation request for doctrine/mongodb dev-master -> satisfiable by doctrine/mongodb[dev-master].
    - doctrine/mongodb dev-master requires ext-mongo ^1.5 -> the requested PHP extension mongo is missing from your system.
  Problem 3
    - doctrine/mongodb 1.4.x-dev requires ext-mongo ^1.5 -> the requested PHP extension mongo is missing from your system.
    - doctrine/mongodb-odm dev-master requires doctrine/mongodb ~1.3 -> satisfiable by doctrine/mongodb[1.4.x-dev].
    - Installation request for doctrine/mongodb-odm dev-master -> satisfiable by doctrine/mongodb-odm[dev-master].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php5/cli/php.ini
    - /etc/php5/cli/conf.d/05-opcache.ini
    - /etc/php5/cli/conf.d/10-pdo.ini
    - /etc/php5/cli/conf.d/20-curl.ini
    - /etc/php5/cli/conf.d/20-json.ini
    - /etc/php5/cli/conf.d/20-readline.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

注意:

我已经在mac机器上安装了MongoDB，安装的版本是

Shyleen:~ shyleenrodrigues$ mongo --version
MongoDB shell version v3.4.6

Answer 1

doctrine/mongodb 1.4.x-dev requires ext-mongo ^1.5 -> the requested PHP extension mongo is missing from your system.

好像没有安装php mongodb扩展。所以请参阅mongodb documentation php driver .

您只需通过pecl安装此扩展即可，如果安装了 php-dev 软件包 - 取决于您的 php 版本。

sudo apt-get install php7.0-dev // for example on ubuntu linux!!
sudo pecl install mongodb

重新启动 php 并重新运行 Composer 并检查其输出。

好吧，在 Mac 上似乎有点不同，你可以阅读 here (12.).
