Package php-mcrypt is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php-mcrypt' has no installation candidate

Answer 1

在PHP7.2中，Mcrypt已被废弃，因此默认情况下它不可用。

您仍然可以使用pecl安装mcrypt扩展。这些说明是针对apache web服务器的。

# Install prerequisites
sudo apt-get install php-dev libmcrypt-dev gcc make autoconf libc-dev pkg-config

# Compile mcrypt extension
sudo pecl install mcrypt-1.0.1
# Just press enter when it asks about libmcrypt prefix

# Enable extension for apache
echo "extension=mcrypt.so" | sudo tee -a /etc/php/7.2/apache2/conf.d/mcrypt.ini

# Restart apache
sudo service apache2 restart

那应该能让你走了。

从长远来看，您可能希望取代mcrypt，这是有原因的。

Answer 2

我做了下面的工作.

sudo add-apt-repository ppa:ondrej/php
sudo apt-get install php7.1-mcrypt

如果运行php5.6或7.0，则可以使用以下方法

sudo apt-get install php5.6-mcrypt
sudo apt-get install php7.0-mcrypt

Answer 3

php已在php7.2 http://php.net/manual/en/migration71.deprecated.php中被删除。
