If you followed instructions like these:

Which tell you to do the following:

<pre><code>$ curl -sS https://getcomposer.org/installer | php

Then it's likely that you, like me, ran those commands and didn't read the next part of the page telling you to stop referring to composer.phar by its full name and abbreviate it as an executable (that you just renamed with the mv command). So this:

<pre><code>$ php composer.phar update friendsofsymfony/elastica-bundle

blocks|key|4663278|text|简单的回答是，导航到您已经有要运行的composer.json文件的目录(最好是您的项目文件夹)，然后将composer下载到同一文件夹中，然后立即运行安装命令，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4663279|+php+composer.phar+install|code-block|syntax|javascript|4663280|这将自动查找composer.json并运行所需的脚本。祝好运。这些东西对于终端巫师来说是轻而易举的，对我们其他人来说则是完全奇怪的。|4663281|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Easy answer, navigate to the directory where you already have the composer.json file that you want to run (ideally your project folder) then download composer into the same folder, then instantly run the install command like so:

<pre><code> php composer.phar install
</code></pre>

This will automatically find the composer.json and run your required scripts. Good luck. This stuff is a breeze for terminal wizards and totally bizarre to the rest of us

blocks|key|157037|text|如果composer已经安装好了，那么您所需要做的就是知道composer.phar文件的位置(它的目录)，然后转到symfony项目，在这个项目中安装composer.json，然后从该目录执行composer.phar文件。在windows中，这是你必须要做的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|157038|symfony+project+directory_where_composer.json_is>php+the_directory_where_composer.phar_is/composer+update+|code-block|syntax|javascript|157039|就这样|157040|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

if the composer is already install all you need is to know where the composer.phar file is (its directory) after that you move to your symfony project where you have the composer.json and from that directory you execute your composer.phar file. In windows here is what you have to do.

<pre><code>symfony project directory_where_composer.json_is&gt;php the_directory_where_composer.phar_is/composer update

Or you can create yii2 project using this command:

To solve this issue the first thing you need to do is to get the last version of composer :

<pre><code>curl -sS https://getcomposer.org/installer | php
</code></pre>

I recommend you to move the composer.phar file to a global “bin” directoy, in my case (OS X) the path is:

<pre><code>mv composer.phar /usr/local/bin/composer.phar
</code></pre>

than you need to create an alias file for an easy access 

<pre><code>alias composer='/usr/local/bin/composer.phar'
</code></pre>

If everything is ok, now it is time to verify our Composer version:

<pre><code>composer --version
</code></pre>

I know that maybe my answer is too specific for a embedded QNAP server, but I ended here trying to install Yii:

For me, inside a QNAP NAS through PuTTY, after trying all tricks above, and updating PATH to no avail, the only cmd line that works is:

<pre><code> /mnt/ext/opt/apache/bin/php /usr/local/bin/composer create-project yiisoft/yii2-app-basic basic
</code></pre>

Of course, adapt your path accordingly...

If I do a <code>which composer</code>, I have a correct answer, but if I do a <code>which php</code> nothing returns.

Besides that, trying to run 

<code>/mnt/ext/opt/apache/bin/php composer create-project yiisoft/yii2-app-basic basic</code> 

or referring to 

<code>composer.phar</code> 

didn't worked too...

blocks|key|157467|text|只需以管理员身份打开cmd并进入您的项目文件夹，然后使用composer命令检查它是否正常工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|157468|上面的错误是因为编写器不能全局访问。因此，您需要以管理员身份运行"cmd“。|157469|这对我来说工作得很好。|157470|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Just open cmd as Administrator and go into your project folder and check it is working or not using composer command.

The above error is because of the composer is not accessible globally.
So you need to run "cmd" as Administrator. 

This is working fine for me.

I had an issue getting a package.json's script to run <code>composer dumpautoload</code>.

I had the file <code>/usr/local/bin/composer.phar</code>, and also the file <code>~/.bash_profile</code> (on OSX) contained:

<pre><code>alias composer="php /usr/local/bin/composer.phar"
</code></pre>

This allowed <code>composer</code> to work from the command line, but it didn't allow scripts to execute composer.

The fix was this:

<pre class="lang-sh prettyprint-override"><code>$ cd /usr/local/bin
$ mv composer.phar composer
$ sudo chmod +x composer // +x allows the file to be executable, such as by CLI scripts
</code></pre>

But that yielded this error <code>Could not open input file: /usr/local/bin/composer.phar</code>

The fix was to update <code>~/.bash_profile</code> (sudo nano ~/.bash_profile), and change the composer alias to:

<pre><code>alias composer="php /usr/local/bin/composer"

# ie: `.phar` extension removed
</code></pre>

Now everything is behaving as expected.

I am new to symfony2 and reading <a href="http://tutorial.symblog.co.uk/#tutorial-parts" rel="noreferrer">symblog</a>. In third chapter while trying with data-fixtures I tried the command: 

<code>php composer.phar update</code> 

but I got the error: 

<code>Could not open input file: composer.phar</code>

So I googled a little and tried 

<pre><code>php composer.phar install
</code></pre>

but still getting the same error. So please guide how to deal with this composer to install new extentions or bundles like data-fixtures in symfony2 using wamp.
