Laradock 下无法运行 phpunit

我在 Laradock 环境中使用命令：

docker-compose exec workspace bash

进入工作台，然后在 larabbs 项目根目录运行 phpunit 报错：

root@d3eeba2c3b60:/var/www/larabbs# phpunit
./vendor/bin/phpunit: line 1: XSym: command not found
./vendor/bin/phpunit: line 2: 0026: command not found
./vendor/bin/phpunit: line 3: 7fbf1de96873e3062c1fd6a0321048dc: command not found
./vendor/bin/phpunit: line 4: ../phpunit/phpunit/phpunit: No such file or directory

请问有大佬遇见过这种情况吗，应当如何解决？
