我有问题。我在CircleCI中运行自动测试，但测试结果失败了。然后我用SSH调试。当我在终端中运行相同的测试命令时，结果是成功的。
命令：
$ cd tests; codecept run && cd - || exit 1 returned exit code 1
自动测试结果：
Time: 9.93 seconds, Memory: 32.75Mb
OK (24 tests, 52 assertions)
PHP Warning: Uncaught exception 'PHPUnit_Framework_Exception' with message 'var_export does not handle circular references' in /home/ubuntu/.composer/vendor/codeception/codeception/src/Codeception/Subscriber/ErrorHandler.php:49

使用SSH结果进行调试：

我试图在依赖项中设置memory_limit。
$ echo "memory_limit = 2048M" > ~/.phpenv/versions/$(phpenv global)/etc/conf.d/memory.ini
但结果也失败了。
