在localhost上运行Symfony2上的composer更新时出现运行时异常

Question

我在使用composer更新依赖项时遇到运行时异常。这是跟踪：

我还不清楚这是怎么回事！现在我甚至无法在我的应用程序中添加供应商包:(

当我回答n时，我问我是否要放弃对修改过的文件进行更改时，我做对了..

Updating sensio/distribution-bundle (v2.2.6 => 2.2.x-dev 2779c8b)
    The package has modified files:
--- somes files...

Answer 1

我经常收到此错误。以下是另一个包的示例：

您可以输入$git diff来查看作曲家正在谈论的变化。

如果您未对sensio/distribution-bundle进行任何更改，只需输入 y 并按输入即可。 （作曲家会问“你想放弃这些改变吗？”

这是因为作曲家可以看到sensio/distribution-bundle中有一些修改。

有两种情况：

1 您确实对供应商文件进行了一些更改，在本例中为sensio/distribution-bundle。你永远不应该这样做...如果你想这样做，只需在这种情况下分叉sensio/distribution-bundle并将其添加到你的composer.json文件中：

"repositories": [
      {
        "type": "vcs",
        "url": "git@github.com:YourUsername/SensioDistributionBundle.git"
      },
    ],
"require": {
        //...
        "sensio/distribution-bundle":"dev-master",
        //...
      },
//...

2 您尚未进行任何更改。

您已对供应商文件进行了一些更改，在本例中为sensio/distribution-bundle。 In也可能发生，具体取决于您使用的IDE或OS。在这种情况下，始终回答YES。如果这些文件是由IDE或OS创建的，只需将它们添加到.gitignore文件中：

# PHP Storm generated files #
.idea
# OS generated files #
*.DS_Store
