php 要启用扩展，请验证它们是否在这些 .ini 文件中启用 - Vagrant/Ubuntu/Magento 2.0.2

To enable extensions, verify that they are enabled in those .ini files - Vagrant/Ubuntu/Magento 2.0.2

提问by Verse

When installing Magento 2.0.2 via composer getting this error:

通过 Composer 安装 Magento 2.0.2 时出现此错误：

Problem 1
 - Installation request for magento/product-enterprise-edition 2.0.2 -> satisfiable by magento/product-enterprise-edition[2.0.2].
 - magento/product-enterprise-edition 2.0.2 requires ext-gd * -> the requested PHP extension gd is missing from your system.

To enable extensions, verify that they are enabled in those .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-imap.ini
- /etc/php5/cli/conf.d/20-json.ini
- /etc/php5/cli/conf.d/20-mcrypt.ini
- /etc/php5/cli/conf.d/20-pdo_pgsql.ini
- /etc/php5/cli/conf.d/20-pgsql.ini
- /etc/php5/cli/conf.d/20-pspell.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.

I have installed php5-cli, php5-curl.

我已经安装了 php5-cli、php5-curl。

@Verse answer works fine. But there is a small thing I would like to add. instead of installing php5-mbstring, php5-gd, php5-intl, php5-xsl. This answer is based on @Regolith answer: Package has no installation candidate.

On Ubuntu 16.04 php7 is now the default, so if you follow the top answers and are still having this issue, check your php version.

在 Ubuntu 16.04 上 php7 现在是默认设置，因此如果您按照最佳答案进行操作并且仍然遇到此问题，请检查您的 php 版本。

php --version

If your default php version is php7, but you followed an answer using php5 packages, you can use the following command to set the default version of php to php5.6:

如果您的默认 php 版本是 php7，但您遵循使用 php5 包的答案，则可以使用以下命令将 php 的默认版本设置为 php5.6：

sudo update-alternatives --set php $(which php5.6)

The exact name of the extension depends on the repository from which you got PHP but look here. For example on CentOS:

扩展的确切名称取决于您从中获取 PHP 的存储库，但请查看此处。例如在 CentOS 上：

yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring php56w-bcmath

yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring php56w-bcmath
