Question

我已Symfony Demo Application启动并运行，现在我正在尝试install API Platform as a standalone bundle。

我使用PHP 7.0.10和最新的作曲家，但我之前的测试是使用PHP 5.6.20。

当我尝试将API Platform Core添加为依赖项时，收到以下错误消息：

$ composer require api-platform/core
Using version ^1.1 for api-platform/core
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for symfony/symfony (locked at v3.2.8, required as ^3
.2) -> satisfiable by symfony/symfony[v3.2.8].
    - api-platform/core v1.1.0 requires phpdocumentor/reflection ^1.0.7 -> satis
fiable by phpdocumentor/reflection[1.0.7].
    - api-platform/core v1.1.1 requires phpdocumentor/reflection ^1.0.7 -> satis
fiable by phpdocumentor/reflection[1.0.7].
    - Conclusion: don't install phpdocumentor/reflection 1.0.7
    - Installation request for api-platform/core ^1.1 -> satisfiable by api-plat
form/core[v1.1.0, v1.1.1].


Installation failed, reverting ./composer.json to its original content.

Answer 1

在composer.json文件中：

查找

"symfony/symfony": "3.2.*",

替换为：

"symfony/symfony": "3.3.*",

...或：

"symfony/symfony": "^3.2.*",

您可能首先需要（想要）运行composer update，然后使用composer require api-platform/core添加您的api-platform软件包，以便正确加载所有依赖项，但它已经加载了不是必需的。

Answer 2

使用PHP 7.x，您应该使用^2.0，例如

composer require api-platform/core ^2.0

^{注意：要解决PHP 7.x要求，可以尝试添加--ignore-platform-reqs。}

如果您收到有关minimum-stability的错误，请将其更改为beta文件中的composer.json。
