JonnyW\PhantomJs\Exception\NotWritableException

[Jestergnet]

jonnyw/php-phantomjs (v4.6.1)

File could not be written to system as target is not writable: /tmp/dd5ca8b3b0eb4871f0c5 in /framework/vendor/jonnyw/php-phantomjs/src/JonnyW/PhantomJs/Cache/FileCache.php at line 65

I tried:
$ client-> setTempDir (".....");
I did not help ...

And
$client = \JonnyW\PhantomJs\Client::getInstance();
$client->getProcedureCompiler()->disableCache();

The error is not still from gone.

What's the matter?
