Question

我目前正试图让我的Laravel应用程序在Plesk Onyx后面运行。现在，当我尝试运行composer install时，收到以下错误消息：

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

行。我肯定理解这些错误。我运行的是Debian 9和＃34; PHP by OS Vendor＆＃34;是7.0.27。但是，我知道服务器上安装了PHP 7.1+（甚至7.2），因为Plesk允许我选择（对于域和vhost）这些版本。我现在的问题是：如何告诉作曲家使用服务器上安装的某个PHP版本，以及如何使用Plesk在Debian下工作？

编辑：我没有全局安装Composer。只需https://getcomposer.org/download/＆＃34;命令行安装＆＃34;。

Answer 1

以下是：

找到Plesk使用的PHP路径。就我而言，这是/opt/plesk/php/。在此文件夹中，根据安装的PHP版本存在文件夹：7.0，7.1，7.2。因此php composer.phar install变为/opt/plesk/php/7.2/bin/php composer.phar install。＆安培;有用。： - ）

Answer 2

您可以使用composer.json中的platform设置来模拟PHP版本：

"config": {
    "platform": {
        "php": "7.1"
    }
},

即使您使用7.0进行实际安装，Composer也会假设在安装和更新期间PHP版本为7.1。

这只会影响Composer的安装和更新 - 如果要运行应用程序的控制台命令，则需要使用正确的二进制文件（对于Web服务器也是如此）。但是，设置此选项将使您的Composer安装和更新更具可预测性，因此无论如何都值得这样做。
