Error - Unable to find `dot` command of the GraphViz package

Question

Ubuntu precise (12.04.1 LTS)

I'm rather new to PEAR.

I installed PEAR. Then, using pear I installed phpdoc.

It seems to be working great except for the graphing functions.

I ran this command:

/var/www/site5 $ phpdoc -f models/classes.php -t ./docs/classes

Collecting files .. OK

I realized that in my apache virtual host for this site I had this line:

    php_value include_path ".:/var/www/site5/includes"

And so I thought maybe that was preventing inclusion of other directories... ?

So I tried changing the line to this:

    php_value include_path ".:/var/www/site5/includes:/usr/lib/php:/usr/share/php"

That didn't work either, so I finally commented out the line, but still the same error.

In case this helps, inside of /usr/share, I ran this command:

/usr/share$ find -name "*GraphViz*"
./php/phpDocumentor/vendor/phpdocumentor/graphviz/src/phpDocumentor/GraphViz
./php/phpDocumentor/vendor/phpdocumentor/graphviz/tests/phpDocumentor/GraphViz
./php/Image/GraphViz.php
./php/test/Image_GraphViz
./php/data/phpDocumentor/features/generate-documentation/graphs/GenerateClassDia
gramUsingGraphViz.feature
/usr/share$

I don't see why this is not working. Thanks for your help.

Answer 1

I had this problem when generating PHPDoc, during the "Transform analyzed project into artifacts"-phase. I solved this problem by executing the following command

sudo apt-get install graphviz

Answer 2

I tried installing it using PEAR.

sudo pear install Image_GraphViz

I ended up just upgrading (practically) EVERYTING and it worked.

apt-get --fix-missing
sudo apt-get install php-pear --fix-missing
sudo apt-get install php-pear
sudo apt-get install php5-xsl
sudo apt-get update

Not sure what exactly did the trick, but it works now.

Answer 3

For the non-apt-getters.

brew install graphviz

sorted it out for me, also needed it for PHPDoc.

Answer 4

I had the same issue. You'll need to make sure you have "dot" installed.

"dot" is included with GraphViz.
