使用本地目录将symfony 2.8升级到3.4 [英] upgrade symfony 2.8 to 3.4 using local directory

问题描述

我正在寻找如何使用本地目录将Symfony 2.8框架升级到3.4。
我的开发环境无法访问互联网。

I am looking how to upgrade the framework Symfony 2.8 to 3.4 using local directory. My development environment doesn't have access to internet.

我关注了 https://getcomposer.org/doc/05-repositories.md#path

我下载了Symfony 3.4，并将其存放在与Synfony 2.8相同的目录中

I download Symfony 3.4 and deposit it in the same directory as Synfony 2.8

Frameworks 
    Symfony-2.8
    Symfony-3.4

然后我像下面这样配置composer.json文件（symfony 2.8）：

Then I configured the composer.json file (symfony 2.8) like this :

"repositories": [
    {
        "type": "path",
        "url" : "/frameworks/symfony3-4"
    }
],
 "require": {
        "/frameworks/symfony3-4": "*"
},

当我尝试更新时：

Composer update

我有此错误：

Problem 1
  - The requested package ../symfony3-4 could not be found in any version, there
 may be a typo in the package name.

Potential causes:
 A typo in the package name
 The package is not available in a stable-enough version according to your minimum-stability setting
 see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

您有建议吗？

推荐答案

在您的require语句中使用 symfony / symfony： ^ 3.0

use "symfony/symfony": "^3.0" in your require statement
