PHP 7.2 抛出 run "composer require symfony/dotenv"，7.1 没有

Question

在 PHP 7.1 中构建(和工作)的 Symfony 4.2 应用程序，当切换到 7.2 时抛出

Fatal error: Uncaught RuntimeException: Please run "composer require symfony/dotenv" to load the ".env" files configuring the application...

此外， composer update yield Nothing to install or update进而

Script cache:clear returned with error code 255 !! !! Fatal error: Uncaught RuntimeException: You need to add "symfony/framework-bundle" as a Composer dependency. in G:\Documents\workspace\mana\bin\console:14

将 composer.json 更新为需要 PHP 7.2 后，它现在包括:

"require": {
    "php": "^7.2",
    "ext-ctype": "*",
    "ext-iconv": "*",
    "beberlei/doctrineextensions": "^1.1",
    "easycorp/easyadmin-bundle": "^2.0",
    "knplabs/knp-snappy-bundle": "^1.6",
    "ob/highcharts-bundle": "^1.6",
    "sensio/framework-extra-bundle": "^5.1",
    "symfony/asset": "4.2.*",
    "symfony/console": "4.2.*",
    "symfony/dotenv": "4.2.*",
    "symfony/expression-language": "4.2.*",
    "symfony/flex": "^1.1",
    "symfony/form": "4.2.*",
    "symfony/framework-bundle": "4.2.*",
    "symfony/monolog-bundle": "^3.1",
    "symfony/orm-pack": "*",
    "symfony/process": "4.2.*",
    "symfony/security-bundle": "4.2.*",
    "symfony/serializer-pack": "*",
    "symfony/swiftmailer-bundle": "^3.1",
    "symfony/templating": "4.2.*",
    "symfony/test-pack": "^1.0",
    "symfony/translation": "4.2.*",
    "symfony/twig-bundle": "4.2.*",
    "symfony/validator": "4.2.*",
    "symfony/web-link": "4.2.*",
    "symfony/webpack-encore-bundle": "^1.0",
    "symfony/yaml": "4.2.*"
},

编辑:如果按照错误消息中的建议， composer update运行，出现以下情况。正如在 composer.json 中所见以上，这是无稽之谈。

Fatal error: Uncaught RuntimeException: You need to add "symfony/framework-bundle" as a Composer dependency. in G:\Documents\workspace\mana\bin\console:14

编辑#2:
这似乎不是 Symfony 或 PHP 问题。我在 Windows 中工作，并且有一台 Hyper-V Ububtu 18 服务器在 Apache/2.4.29、PHP 版本 7.2.19 中运行该应用程序的克隆，没有问题。使整理起来变得更加困难。搁置这个 Q？

编辑#3:
恢复了两个月前的 Windows 镜像并获得了相同的效果。返回当前图像并了解到上述错误在此框的 PHP 7.10 和 7.16 之间的某个位置开始。将 Symfony 升级到 4.3 没有帮助。啊啊啊啊啊!

最终编辑:
解决这个问题超出了我的技能范围。我将以 PHP 7.2.20 的输出结束。没有创建 dev.log。 Netbeans 11 似乎无法识别 xdebug。这里:

Answer 1

我也遇到过这个问题，但就我而言，问题是 composer 已更新到 2.0.11，这就是产生关于 Please run "composer require symfony/dotenv" to load the ".env" files configuring the application. 的错误的原因。我回到了 Composer 2.0.8，一切又都好了。我相信 2.0.9 也有效。
