symfony - 在 symfony 3.4 上安装 FOSUserBundle 时出错

Question

在官方文档中，它说这是第一步

$ Composer 需要friendsofsymfony/user-bundle“~2.0”

这会返回给我这个错误

Answer 1

这是一个已知错误，因为 random_compat 库最近由于某种原因更新为奇怪的 9.99.99 版本，并且包的依赖项声明错误。您可以做的是在您自己的项目中明确要求 ^2.0 版本。

运行:

composer require paragonie/random_compat ^2.0

或者您可以使用

修改composer.json

"require": {
    ...
    "paragonie/random_compat": "^2.0",
    ...
},

然后，正常安装您的 bundle 。
