Symfony 3.3.18:Composer更新/安装/需要fire=>内存不足[重复]

Question

我试图从Symfony 3.3升级一个项目。我得到了这个错误，当我运行作曲家更新，作曲家安装后删除composer.lock和作曲家要求。

PHP致命错误：第223行的phar://C:/Users/bbarhoum/Documents/ComposerSetup/bin/composer.phar/src/composer/dependencysolver/Solver.PHP中内存不足（分配了1601437696）（试图分配268435456字节）

这是我的composer.json：

Answer 1

尝试运行命令以删除PHP的内存限制。

php -d memory_limit=-1 composer update

您可能需要使用composer exe的绝对路径。

如果这不起作用，请检查您的PHP版本是否适用于x86或x64，如果可能，请更改为x64版本。

另外，请确保已将composer更新为最新版本，因为它将提高性能<代码>作曲家自我更新

希望这对我有帮助，因为它为我做了很多次。
