PHPCS未在命令行上運行？

Question

當我phpcs --version類型，而不是獲得的版本號，我得到的是這樣的：

/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>' 

它看起來像它不讀PHP正確。我錯誤配置了什麼？

我所做的只是sudo pear安裝PHP_CodeSniffer。當我再次運行它，我得到：

梨/ PHP_CodeSniffer已經安裝並是一樣的發佈版本1.3.5

當PEAR並安裝一個的PHP_CodeSniffer，它改變了主要的第一行phpcs腳本，以便#!行指向您系統上的PHP可執行文件。

所以安裝前，行看起來是這樣的：#!@php_bin@和安裝後，它會是這個樣子（具體取決於安裝PHP在哪裏）：#!/usr/bin/php

PEAR有一個配置設置告訴它哪裏是PHP可執行文件安裝。您可以通過運行pear config-show並查找PHP CLI/CGI binary (php_bin)的值來查看此值。您需要確保這個值實際上是您系統上PHP的位置，否則所有腳本安裝（如PHPUnit）都會有類似的問題。

檢查此值的最佳方法是運行which php併爲PEAR配置變量設置該值。然後重新安裝PHP_CodeSniffer，以便重新進行更換。

所以我的系統，我應該這樣做：

$ 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 

如果一切順利的話，你應該看到您的新phpcs文件的正確#!行：

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

如果看起來正確的話，你將能夠毫無問題地運行phpcs命令。

我苦苦掙扎了一段時間，但終於弄清楚了 - 如果您直接調用的PHP命令是真實可執行文件的shell腳本包裝器，則需要編輯phpcs腳本的第一行以調用PHP通過/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 - 修復前：

~$ 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 7: 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) 

修復程序後：

~$ 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) 

現在我可以在PhpStorm配置CodeSniffer。
