php - Composer : Allowed memory size error when installing package

Question

当我跑 composer require yab/laravel-scout-mysql-driver这是我得到的输出:

Using version ^2.40 for yab/laravel-scout-mysql-driver
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/Cellar/composer/1.3.2/libexec/composer.phar/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52

我正在运行 Composer 1.9.2。

这是我使用 -vvv 时输出的最后几行:

我的内存限制是 128M。 https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors除了增加我的内存限制之外，似乎没有提供很多见解，但似乎 128M 应该足够了？
php -d memory_limit=-1 /usr/local/bin/composer require yab/laravel-scout-mysql-driver没有帮助 - 我收到了“允许的内存大小为 1610612736 字节用尽”错误。与 memory_limit=1024M 相同.

我做了 php --ini并从中得到 /usr/local/etc/php/7.1/php.ini ，我对其进行了编辑以将内存限制更改为 1024MB 并得到相同的结果:“允许的内存大小为 1610612736 字节”。

奇怪的是，“允许的内存大小”在每个实例中都完全相同。就像我所做的实际上没有改变内存大小。

有任何想法吗？

(可能是) Composer Update failed -- out of memory 的重复
我在相同版本(PHP 7.1，Composer 1.9.x)和完全相同的内存限制(经过调查后在 Composer 中编码/定义)遇到了同样的问题。
所以，当你遇到这种错误时要做的第一件事就是告诉 Composer 不要用变量来限制内存，像这样:COMPOSER_MEMORY_LIMIT=-1 composer require "xxx/yyy"这是推荐的方式，但有时它是行不通的。
在我的项目中，似乎每次我执行 composer require xxx 时，composer.lock 都会损坏。 .
所以为了“修复”它，我这样做:

删除您的 vendor文件夹 ( rm -fr vendor )

删除 composer.lock ( rm composer.lock )

确保您的 composer.json包含您的新需求(它应该在那里，因为之前的 composer require )，如果没有，添加它

做一个新鲜的composer install

此时，要么您将清楚地看到依赖项问题，要么将安装所有内容。
我成功地做到了 2 次。
