跳过安装斌/ classmap_generator.php ......由Zend框架2库

Question

的更新当我尝试在我的项目更新ZF2，我得到这样的警告：

# php composer.phar update 
Loading composer repositories with package information 
Updating dependencies (including require-dev) 
    - Installing zendframework/zendframework (2.1.5) 
    Loading from cache 

    Skipped installation of bin/classmap_generator.php for package zendframework/zendframework: name conflicts with an existing file 
zendframework/zendframework suggests installing doctrine/common (Doctrine\Common >=2.1 for annotation features) 
zendframework/zendframework suggests installing ext-intl (ext/intl for i18n features) 
zendframework/zendframework suggests installing ircmaxell/random-lib (Fallback random byte generator for Zend\Math\Rand if OpenSSL/Mcrypt extensions are unavailable) 
zendframework/zendframework suggests installing pecl-weakref (Implementation of weak references for Zend\Stdlib\CallbackHandler) 
zendframework/zendframework suggests installing zendframework/zendpdf (ZendPdf for creating PDF representations of barcodes) 
zendframework/zendframework suggests installing zendframework/zendservice-recaptcha (ZendService\ReCaptcha for rendering ReCaptchas in Zend\Captcha and/or Zend\Form) 
Writing lock file 
Generating autoload files 

什么错吗？这些冲突的原因是什么？如何正确更新ZF2？

通常没有什么可担心的，最可能的解释是您删除了zendframework（或您的整个供应商dir）并忘记删除bin/classmap_generator.php文件，因此它看到它已经存在并跳过安装该文件。
