Composer更新没有'；对我来说不起作用 - Composer update doesn't work in my case

我在我的网站上安装了Laravel 5.0（通过FTP）。然后我尝试通过SSH连接，并使用Composer进行更新。然而，我得到了这个错误。（我的PHP是5.5版本，我检查了phpinfo函数）。

我控制了cli-v，但找不到这个命令。

后来我尝试了以下内容：

$ php -d register_argc_argv=1 "./composer.phar" install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - league/flysystem 1.0.16 requires php >=5.4.0 -> your PHP version (5.3.28) or value of "config.platform.php" in composer.json does not satisfy that requirement.
    - league/flysystem 1.0.16 requires php >=5.4.0 -> your PHP version (5.3.28) or value of "config.platform.php" in composer.json does not satisfy that requirement.
    - Installation request for league/flysystem 1.0.16 -> satisfiable by league/flysystem[1.0.16].

我怀疑这是一个重要的错误：

警告：应该通过PHP的CLI版本调用Composer，而不是通过cgi-fcgi SAPI

尝试which php查看PHP二进制文件的指向，然后尝试locate bin/php查看系统的其他版本。

还要注意：

我的PHP版本是5.5；我检查了phpinfo函数

你不同意的地方：

X-Powered-Bor:PHP/5.3.28

使用完全限定的路径，尝试使用locate发现的PHP二进制文件的其他副本。例如：

/usr/bin/php55-cli composer.php update

如果这个主机有一个5.5 CGI二进制文件和一个5.3控制台二进制文件，他们可能不知道自己在做什么——5.3现在应该不再受支持。如果您自己没有成功修复它，请创建一个支持票证，并请求php从shell调用5.5控制台二进制文件。

更新：根据评论中的对话，上面似乎解决了一个问题，暴露了另一个问题。新的问题是Composer命令越来越远，它试图再次调用使用php二进制文件的PHP助手。这导致了最初的问题（这是web服务器二进制文件，是5.3而不是5.5）

要解决此问题，我建议您（a）创建一个本地php可执行文件以指向所需的版本，然后（b）重置系统路径。我会在你的项目目录中尝试以下内容：

ln -s /usr/bin/php55-cli ./php
PATH=. ./php composer.phar update

这将创建一个指向所需PHP版本的符号链接，然后将系统路径临时重置为当前目录。

如果这还不能完全解决问题，您可能需要将您的符号链接放在一个更永久的位置（例如~/bin/php并修改您的shell启动文件。在惊呼它不起作用之前，请先考虑一下-学习如何独立完成这项工作的最佳方法是尝试！
