在Amazon Linux上安装PHP pear的Structures_Graph之后无法找到“Structures / Graph.php”

Question

I installed pear and found that I have the Structures_Graph directory inside pear directory -

/home/ec2-user/pear/tests

But, I cannot find the Structures/Graph.php and Structures/Graph/Node.php as mentioned in https://pear.php.net/package/Structures_Graph/docs/latest/li_Structures_Graph.html

I was following this article http://www.codediesel.com/algorithms/building-a-graph-data-structure-in-php/, following which installation of Structures_Graph has to be done with this -

pear install Structures_Graph

I get -

pear/Structures_Graph is already installed and is the same as the released version 1.1.1
install failed

Answer 1

I doubt that /home/ec2-user/pear/tests is your pear directory; you probably have a system-wide pear installation.

Get its location with

$ pear config-get php_dir
