降级学说ORM 2.5至2.4

Question

我要降级学说ORM 2.5至2.4以解决此错误：

syntax error, unexpected '[', expecting ')'

注意：我的php版本：5.3（php 5.4及以后版本需要的学说2.5）

并在composer.json文件中写下此代码：

{
    "require": {
        "doctrine/common": "2.4.*",
        "doctrine/dbal": "2.4.*",
        "doctrine/orm": "2.4.*"
    }
}

和此代码中的CMD中运行Composer任务：

composer install

但作曲家下载学说2.5

如何通过作曲家下载教义2.4

Answer 1

我刚刚进行了快速测试，然后下载2.4

只需将此composer.json放入一个文件夹中，一个运行 composer install：

composer.json

{
    "name": "test/test",
    "description": "test",
    "license": "no",
    "require": {
        "doctrine/common": "2.4.*",
        "doctrine/dbal": "2.4.*",
        "doctrine/orm": "2.4.*"
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "stable"
}

正如您在Composer安装输出中所看到的，doctrine/common，doctrine/dbal和doctrine/orm都是版本2.4.x。我也使用"preferred-install": "source"和"minimum-stability": "dev"相同的结果进行测试。
