PHP | "系统中缺少所请求的PHP扩展名bcmath."

Question

问候开发者,

我试图在我最近启动的开发服务器上使用composer作为我的PHP项目,由于某种原因我无法做到.我成功安装了composer,但是,当我尝试运行require命令时,我收到以下错误:

root@webserver:/var/mypersonal/index# composer require php-amqplib/php-amqplib
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_openssl.dll' - /usr/lib/php/20151012/php_openssl.dll: cannot open shared object file: No such file or directory in Unknown on line 0
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Using version ^2.6 for php-amqplib/php-amqplib
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - php-amqplib/php-amqplib v2.6.3 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - php-amqplib/php-amqplib v2.6.2 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - php-amqplib/php-amqplib v2.6.1 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - php-amqplib/php-amqplib v2.6.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - Installation request for php-amqplib/php-amqplib ^2.6 -> satisfiable by php-amqplib/php-amqplib[v2.6.0, v2.6.1, v2.6.2, v2.6.3].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.0/cli/conf.d/10-opcache.ini
    - /etc/php/7.0/cli/conf.d/10-pdo.ini
    - /etc/php/7.0/cli/conf.d/20-calendar.ini
    - /etc/php/7.0/cli/conf.d/20-ctype.ini
    - /etc/php/7.0/cli/conf.d/20-exif.ini
    - /etc/php/7.0/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.0/cli/conf.d/20-ftp.ini
    - /etc/php/7.0/cli/conf.d/20-gettext.ini
    - /etc/php/7.0/cli/conf.d/20-iconv.ini
    - /etc/php/7.0/cli/conf.d/20-json.ini
    - /etc/php/7.0/cli/conf.d/20-mysqli.ini
    - /etc/php/7.0/cli/conf.d/20-pdo_mysql.ini
    - /etc/php/7.0/cli/conf.d/20-phar.ini
    - /etc/php/7.0/cli/conf.d/20-posix.ini
    - /etc/php/7.0/cli/conf.d/20-readline.ini
    - /etc/php/7.0/cli/conf.d/20-shmop.ini
    - /etc/php/7.0/cli/conf.d/20-sockets.ini
    - /etc/php/7.0/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.0/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.0/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.0/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, deleting ./composer.json.

我假设它与我在运行composer require命令时收到的PHP警告有关,但没有谷歌搜索结果引导我到正确的方向.

另外,我提供了我的/etc/php/7.0/cli/php.ini文件,因为该文件中存在错误.

谢谢.

Answer 5

按类型检查你的php版本: php --version

你会看到这样的东西:

PHP 7.2.9-1+ubuntu16.04.1 ....

那么sudo apt install phpX.X-bcmath XX是php版本,所以对于这个^例子它将是 sudo apt install php7.2-bcmath

在此之后检查模块是否存在类型 php -m | grep bcmath
