无法使用 composer 创建 yii2 项目

Question

我正在尝试使用 composer 创建一个 yii2 项目并收到此错误

我正在使用 ubuntu 16.04 LTS

  root@xuf-SATELLITE-C50t-A:/var/www/html/suppare# composer create-project --prefer-dist yiisoft/yii2-app-basic suppare
    Do not run Composer as root/super user! See https://getcomposer.org/root for details
    Installing yiisoft/yii2-app-basic (2.0.14)
      - Installing yiisoft/yii2-app-basic (2.0.14): Loading from cache
    Created project in suppare
    Loading composer repositories with package information

  Problem 1
    - codeception/phpunit-wrapper 6.0.2 requires sebastian/diff ^3.0 -> satisfiable by sebastian/diff[3.0.0].
    - codeception/phpunit-wrapper 7.0.0 requires sebastian/diff ^3.0 -> satisfiable by sebastian/diff[3.0.0].
    - codeception/phpunit-wrapper 7.0.1 requires sebastian/diff ^3.0 -> satisfiable by sebastian/diff[3.0.0].
    - codeception/phpunit-wrapper 7.0.2 requires sebastian/diff ^3.0 -> satisfiable by sebastian/diff[3.0.0].

我在出现上述错误之前收到 php-mbstring 的缺少扩展错误，因此运行此命令现在我收到上述错误。作曲家创建了不完整的项目，但在浏览器中没有显示错误 sudo apt-get install php-mbstring

Answer 1

好像缺少 phpunit 所以我运行

sudo apt-get install phpunit

它解决了问题
