调用未定义的方法PHP_CodeCoverage_Filter :: addDirectoryToBlacklist（）

Question

I tried running PHP in my code and it shows

$ ./vendor/bin/phpunit
PHP Fatal error:  Call to undefined method PHP_CodeCoverage_Filter::addDirectoryToBlacklist() in /home/petra/myproject/vendor/phpunit/phpunit/src/TextUI/TestRunner.php on line 979

Previously it's running normal.

Here's in the composer.json

"require-dev": {
    ...
    "phpunit/phpunit": "4.6.*", 
    ...
}

Here's the content of phpunit.xml.

<phpunit bootstrap="./test/bootstrap.php">
    <testsuites>
        <testsuite name="Test">
            <directory>./test</directory>
        </testsuite>
    </testsuites>
</phpunit>

The content of ./test/bootstrap.php is just this

require dirname(__FILE__) . '/../vendor/autoload.php';

What did I do wrong?

Answer 1

Just tried manually set the phpunit/php-code-coverage dependency to 2.2.4 and this works.
