My project runs on PHP 5.5 and thus we are using this in `circle.yml`:

```
machine:
   php:
     version: 5.5.31

```

I am getting this error while running `phpunit`:

```
$ phpunit
This version of PHPUnit requires PHP 5.6; using the latest version of PHP is highly recommended.

phpunit returned exit code 1

```

I don’t have any plans to upgrade my project to PHP 5.6 yet. Is there anyway I can change the phpunit version to the one that supports 5.5, i.e. phpunit 4.8.0 and how?

I would advise removing phpunit and then installing the version you need in your dependencies section on circle.yml.

The directions to install a certain version are here: [http://askubuntu.com/questions/428772/how-to-install-specific-version-of-some-package/428778](http://askubuntu.com/questions/428772/how-to-install-specific-version-of-some-package/428778)

```
dependencies:
  pre:
    - sudo apt-get install package=<version>

```

You can also use Composer: [https://phpunit.de/manual/current/en/installation.html](https://phpunit.de/manual/current/en/installation.html)

Thanks! This is what I’m doing. I did not remove and install a different version. But downloaded the target version into the working directory and run from there.

```
machine:
   php:
     version: 5.5.31
dependencies:
  post:
    - wget https://phar.phpunit.de/phpunit-old.phar
    - chmod +x phpunit-old.phar
    - mv phpunit-old.phar phpunit
test:
  override:
    - mkdir -p $CIRCLE_TEST_REPORTS/phpunit
    - ./phpunit --log-junit $CIRCLE_TEST_REPORTS/phpunit/junit.xml

```

It’s working great.
