【问题描述】：
我一直在尝试使用gcloud app deploy 构建一个 PHP 7.4 应用程序，但它失败了：
您的要求无法解决为一组可安装的软件包。 问题一
- jean85/pretty-package-versions 2.0.4 的安装请求 -> 可由 jean85/pretty-package-versions[2.0.4] 满足。
- jean85/pretty-package-versions 2.0.4 需要 composer-runtime-api ^2.0.0 -> 找不到匹配的包。
这是我的composer.json：
{
"require": {
"slim/slim": "^4.0",
"slim/psr7": "^1.3",
"slim/http": "^1.2",
"mongodb/mongodb": "1.5",
"ext-mongodb": "^1.6",
"jean85/pretty-package-versions": "^2.0",
"nesbot/carbon": "^2.52",
"php-di/php-di": "^6.3",
"vlucas/phpdotenv": "^5.3"
},
"require-dev": {
"phpunit/phpunit": "^9.5"
}
}
注意事项：
我在网上找到的所有信息都是关于可能使用 Composer 1 而不是 Composer 2。
关于 Google App Engine 上的 composer 的最大优点是，当我在交互式控制台中输入 composer --version 时，我会得到“2.1.6”，就像在我的本地开发环境中一样。
最后，作为证据，这是 Cloud Build 日志的尾部：

如何确保我在 Google Cloud 运行时中有 composer 2，所以我没有收到“需要 composer-runtime-api ^2.0.0 -> 找不到匹配的包”。错误？
【问题讨论】：
-
这是 Composer 方面的一个错误。看看这个GitHub issue link 并尝试通过运行
composer self-update 2.1.3将 Composer 升级到 2.1.3 的最新版本 -
@PriyashreeBhadra 最新作曲家是 2.1.6，而不是 2.1.3。并且 OP 说他们有“2.1.16”（它不存在，很可能是“2.1.6”的错字）。您提到的错误已在 6 月份解决，因此这里不应该是这种情况。您的建议会使作曲家降级到比最新版本更旧的版本。
-
@yivi 你是对的，但我想确认作曲家的版本，因为他发布了“2.1.16”，但我们假设它的 2.1.6 不存在，因为 2.1.16 不存在。
-
只是让大家知道我通过使用
mongodb/mongodb 1.5、ext-mongodb 1.6并使用extension=mongodb.so添加单行php.ini文件，成功构建了应用程序并无错误地连接到外部MongoDB 集群在我的应用发行版的根目录下。
