我正在尝试
$ composer require --dev phpunit / phpunit ^ 6.5
并收到以下错误：
Problem 1
- phpunit/phpunit 6.5.8 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
所以我多次运行以下
$ sudo apt-get install php-mbstring
并获取
php-mbstring is already the newest version (1:7.2+60ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
$ php --ini
给出：
Configuration File (php.ini) Path: /etc/php/7.0/cli
Loaded Configuration File: /etc/php/7.0/cli/php.ini
我也没有提到过
中的行（无关/错误操作） extension=php_mbstring.dll
/etc/php/7.0/cli/php.ini
我仍然收到“mbstring is missing from your system”错误。
我在Ubuntu 18.04上
修改
composer命令也给出：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_mbstring.dll' - /usr/lib/php/20151012/php_mbstring.dll: cannot open shared object file: No such file or directory in Unknown on line 0
是的，在ubuntu的php.ini中取消注释extension=php_mbstring.dll是错误的/不相关的（见评论）
