Laravel 5 Bluemix 上的应用程序

Question

我一直无法使用 laravel 4.2 和 5.0 将我的 laravel 应用程序部署到 bluemix。这是 blumix 日志中的错误：

这是 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 就是它所抱怨的。对于如何解决这个问题，有任何的建议吗？提前致谢。

Answer 1

您能否在本地运行 composer update 以确保您的 composer.lock 是最新的。还要确保您没有将 composer.phar 推送到 Bluemix。您可以阻止任何文件被推送到 Bluemix，方法是在代码的根目录中创建一个 .cfignore 文件，然后添加您不想上传到该文件的 file/directory 的名称。

Answer 2

您使用的 PHP buildpack 是哪个版本？您可能想通过使用 -b https://github.com/cloudfoundry/php-buildpack 选项推送您的应用程序来试用最新的社区版本。

我知道对于较早版本的 buildpack (v3.1.0)，您实际上需要在一个名为 options.json 的应用程序推送的文件中指定一个名为 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 3

感谢您的回答。我确实有 .cfignore 文件，而且我确实在使用 v3.1.0。

无论如何，作为临时修复，我将所有 ^ 替换为 >= < 相应的值，尽管不需要更新版本的 buildpack。

此外，PHP 版本需要包含在 {} 周围，以便 bluemix 正确获取它："PHP_VERSION"：“{PHP_55_LATEST}”

谢谢
