php composer.phar update does not work with Symfony install

Question

I'm running WAMP on Windows 7 64 Bits. The PATH variable is set to c:\wamp\bin\php\php5.3.13\

 

I'm trying to install Symfony and I do not understand why first line runs and not the second:

This runs successfully:

php c:\wamp\bin\php\php5.3.13\composer.phar update

 
This line fails:

php composer.phar update

With the error:

"Could not open input file: composer.phar"

What can explain this?

 
get_include_path returns : `

.;C:\wamp\bin\php\php5.3.13\php\PEAR`.

Does this mean that if composer.phar is not in PEAR directory 'php composer.phar update' will not work?

Answer 1

Command composer self-update will do the trick.
For example:

1. goto cmd and jump into your project folder if in case
   c:\wamp\www\{yourprojectfolder}
   as your project
   

2. Run this
   cd c:\wamp\www\{yourprojectfolder}
   

3. Use this
   composer self-update

Answer 2

You should try this instead:

composer.phar update

Why would php be aware of your $PATH variable?

Plus, I think $PATH is only used by your shell when dealing with the first word of your command line.

Answer 3

You should logout and then login or restart in order to changes in path becomes available.

Answer 4

Okay this is how i solved it.

1. Download and install git bash
2. open git bash
3. run composer selfupdate or composer self-update

cheers hope this helps you too.
