composer install -n --ignore-platform-reqs不忽略PHP扩展 [英] composer install -n --ignore-platform-reqs not ignoring PHP extension

问题描述

我们有一个运行 composer install -n --ignore-platform-reqs --no-dev 的循环构建，但这不再忽略平台要求。

we have circle build that runs composer install -n --ignore-platform-reqs --no-dev but this is not ignoring the platform requirements anymore.

这是我在圈子日志中看到的内容。 -ignore-platform-reqs 显然不起作用。有什么想法为什么？

This is what i see in the circle log. The --ignore-platform-reqs is clearly not working. Any ideas why please?

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for drupal/core 8.6.13 -> satisfiable by drupal/core[8.6.13].
    - drupal/core 8.6.13 requires ext-pdo * -> the requested PHP extension pdo is missing from your system.
  Problem 2
    - typo3/phar-stream-wrapper v2.1.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - typo3/phar-stream-wrapper v2.1.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - Installation request for typo3/phar-stream-wrapper v2.1.0 -> satisfiable by typo3/phar-stream-wrapper[v2.1.0].

推荐答案

而不是使用-忽略平台要求或提供黑客，最好使用 平台 设置-它使您可以更好地控制平台要求，并且比提供（您的软件包并未真正提供 ext-fileinfo ）：

Instead of using --ignore-platform-reqs or provide hack it is better to mimic your environment using platform setting - it gives you more control about platform requirements and it is more intuitive than provide (your package does not really provide ext-fileinfo):

"config": {
    "platform": {
        "php": "7.2.14",
        "ext-fileinfo": "1.0.5",
        "ext-pdo": "7.2.14",
        "ext-session": "7.2.14",
        "ext-iconv": "7.2.14",
        "ext-zip": "1.15.4"
    }
},

您可以通过在生产环境中调用此命令来找到扩展的实际版本（尽管您可以在扩展版本中放置任何内容-使用任何内容很少见除了 * 作为PHP扩展的约束之外）：

Actual versions of extensions you may find by calling this command on production environment (although you could probably put anything for extensions version - it is quite uncommon to use anything except * as a constraint for PHP extensions):

composer show -p
