PHPCS未在命令行上运行？

Question

当我phpcs --version类型，而不是获得的版本号，我得到的是这样的：

/Applications/drupal/php/bin/phpcs: line 2: ?php: No such file or directory 
/Applications/drupal/php/bin/phpcs: line 3: /Applications: is a directory 
/Applications/drupal/php/bin/phpcs: line 4: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 5: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 6: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 7: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 8: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 9: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 10: Applications: command not found 
/Applications/drupal/php/bin/phpcs: line 11: syntax error near unexpected token `newline' 
/Applications/drupal/php/bin/phpcs: line 11: ` * @author Greg Sherwood <gsherwood@squiz.net>' 

它看起来像它不读PHP正确。我错误配置了什么？

我所做的只是sudo pear安装PHP_CodeSniffer。当我再次运行它，我得到：

梨/ PHP_CodeSniffer已经安装并是一样的发布版本1.3.5

当PEAR并安装一个的PHP_CodeSniffer，它改变了主要的第一行phpcs脚本，以便#!行指向您系统上的PHP可执行文件。

所以安装前，行看起来是这样的：#!@php_bin@和安装后，它会是这个样子（具体取决于安装PHP在哪里）：#!/usr/bin/php

PEAR有一个配置设置告诉它哪里是PHP可执行文件安装。您可以通过运行pear config-show并查找PHP CLI/CGI binary (php_bin)的值来查看此值。您需要确保这个值实际上是您系统上PHP的位置，否则所有脚本安装（如PHPUnit）都会有类似的问题。

检查此值的最佳方法是运行which php并为PEAR配置变量设置该值。然后重新安装PHP_CodeSniffer，以便重新进行更换。

所以我的系统，我应该这样做：

$ which php 
/usr/bin/php 
$ sudo pear config-set php_bin /usr/bin/php 
config-set succeeded 
$ sudo pear uninstall php_codesniffer 
uninstall ok: channel://pear.php.net/PHP_CodeSniffer-1.3.5 
$ sudo pear install php_codesniffer 
downloading PHP_CodeSniffer-1.3.5.tgz ... 
Starting to download PHP_CodeSniffer-1.3.5.tgz (345,113 bytes) 
......................................................................done: 345,113 bytes 
install ok: channel://pear.php.net/PHP_CodeSniffer-1.3.5 

如果一切顺利的话，你应该看到您的新phpcs文件的正确#!行：

$ which phpcs 
/usr/local/bin/phpcs 
$ head -n 1 /usr/local/bin/phpcs 
#!/usr/bin/php 

如果看起来正确的话，你将能够毫无问题地运行phpcs命令。

我苦苦挣扎了一段时间，但终于弄清楚了 - 如果您直接调用的PHP命令是真实可执行文件的shell脚本包装器，则需要编辑phpcs脚本的第一行以调用PHP通过/usr/bin/env：

#!/usr/bin/env /Applications/acquia-drupal/php5_3/bin/php 

，或者只是

#!/usr/bin/env php 

搜索者完全上下文 - 修复前：

~$ head -n 1 pear/bin/phpcs 
#!/Applications/acquia-drupal/php5_3/bin/php 
~$ phpcs --version 
/Users/mryan/pear/bin/phpcs: line 2: ?php: No such file or directory 
/Users/mryan/pear/bin/phpcs: line 3: /Applications: is a directory 
/Users/mryan/pear/bin/phpcs: line 4: Desktop: command not found 
/Users/mryan/pear/bin/phpcs: line 5: Desktop: command not found 
/Users/mryan/pear/bin/phpcs: line 6: Desktop: command not found

/Users/mryan/pear/bin/phpcs: line 8: Desktop: command not found 
/Users/mryan/pear/bin/phpcs: line 9: Desktop: command not found 
/Users/mryan/pear/bin/phpcs: line 10: Desktop: command not found 
/Users/mryan/pear/bin/phpcs: line 11: syntax error near unexpected token `newline' 
/Users/mryan/pear/bin/phpcs: line 11: ` * @author Greg Sherwood <gsherwood@squiz.net>' 
~$ /Applications/acquia-drupal/php5_3/bin/php pear/bin/phpcs --version 
PHP_CodeSniffer version 1.4.5 (stable) by Squiz Pty Ltd. (http://www.squiz.com.au) 

修复程序后：

~$ head -n 1 pear/bin/phpcs 
#!/usr/bin/env php 
~$ phpcs --version 
PHP_CodeSniffer version 1.4.5 (stable) by Squiz Pty Ltd. (http://www.squiz.com.au) 

现在我可以在PhpStorm配置CodeSniffer。
