Question

启动composer.lock时，我的composer install遇到了问题。

我有一个错误：

symfony / var-dumper v4.0.12的安装请求-> symfony / var-dumper [v4.0.12]可以满足。

所以我从composer.lock中删除了它：

一切都可以在composer install命令中进行！

所以，问题是.....为什么将其放在composer.lock上时出现此问题？是否删除它是一个好习惯？我可以用其他解决方案解决吗？

注意：我使用PHP7.1.17和Symfony3.3。

您不应更改composer.lock文件的内容。您只需将version constraints设置在composer.json上，并使用composer install，让作曲家为您解决依赖关系。

composer.lock是由作曲家自动创建的，应保持不变。

如果您在composer.lock上遇到问题并且正在自己开发（没有任何合作者），则可以简单地删除composer.lock文件并再次运行composer install。
