Laravel 5应用程序上的蓝色应用程序

Question

我一直在使用Laravel 4.2和5.0将Laravel应用程序部署到Bluemix很难。这是Blumix日志中的错误：

这是在composer.lock文件中失败的地方：

“require”: {
“nikic/php-parser”: “^1.2.2″,
“php”: “>=5.3.3″,
“symfony/console”: “~2.1″,
“symfony/filesystem”: “~2.1″,
“symfony/finder”: “~2.1″
},

^1.2.2是它在抱怨的。对于如何解决这个问题，有任何的建议吗？预先感谢。

Answer 1

您正在使用哪个版本的php buildpack？您可能需要通过使用-b https://github.com/cloudfoundry/php-buildpack选项推动应用程序来尝试使用最新的社区版本。

我知道，使用buildpack（v3.1.0）的较早版本，您实际上需要在文件中指定一个称为composer_version的特殊属性。

示例options.json：

{
  "PHP_EXTENSIONS": [ "bz2", "zlib", "openssl", "fpm", "tokenizer", "curl", "mcrypt", "mbstring", "pdo"],
  "PHP_VERSION": "PHP_55_LATEST",
  "COMPOSER_VENDOR_DIR":"htdocs/vendor",
  "COMPOSER_VERSION": "latest",
  "WEBDIR": "htdocs/public"
}

Answer 2

您可以在本地运行composer update，以确保您的Composer.lock是最新的。另外，请确保您不会将Composer.phar推向Bluemix。您可以通过在代码的根部创建.cfignore文件，然后添加您不想上传到该文件的文件/目录的名称，从而阻止所有文件被推到蓝色。

Answer 3

感谢您的回答。我确实有.cfignore文件，并且确实使用了v3.1.0。

无论如何，作为临时修复，我用> =＆lt代替了所有 ^;相应的值，不需要构建包的较新版本的Altough。

另外，需要将php版本包裹在{}中才能正确拾取它：" php_version"：" {php_55_latest}"

谢谢
