GuzzleHttp 无法安装在 Laravel 5.8 上

Question

我正在使用 Laravel 5.8，我想安装 GuzzleHttp 包。

首先我尝试运行 composer require guzzlehttp/guzzle，但出现此错误：

Problem 1
    - guzzlehttp/guzzle[7.4.0, ..., 7.4.x-dev] require guzzlehttp/promises ^1.5 -> found guzzlehttp/promises[dev-master, 1.5.0, 1.5.1, 1.5.x-dev (alias of dev-master)] but the package is fixed to 1.4.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - Root composer.json requires guzzlehttp/guzzle ^7.4 -> satisfiable by guzzlehttp/guzzle[7.4.0, ..., 7.4.x-dev].

然后我尝试安装降级版本，因此我运行以下命令：

composer require "guzzlehttp/guzzle:~5.3"

但出现此错误：

Problem 1
    - Root composer.json requires guzzlehttp/guzzle ~5.3, found guzzlehttp/guzzle[5.3.0, ..., 5.3.x-dev] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - anhskohbo/no-captcha is locked to version 3.3.0 and an update of this package was not requested.
    - anhskohbo/no-captcha 3.3.0 requires guzzlehttp/guzzle ^6.2|^7.0 -> found guzzlehttp/guzzle[dev-master, 6.2.0, ..., 6.5.x-dev, 7.0.0-beta.1, ..., 7.4.x-dev (alias of dev-master)] but it conflicts with your root composer.json require (~5.3).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

那么这里出了什么问题呢？如何正确安装 Laravel 5.8 版本的 GuzzleHttp？

Answer 1

尝试在命令中添加 -w 标志：

作曲家需要 guzzlehttp/guzzle -w

您的其他依赖项之一需要 guzzlehttp/promises，当前在您的 composer.lock 中锁定为 1.4.1

-w 标志告诉 Composer 在安装新依赖项时可以更新依赖项。

如果这不起作用，那么您可以尝试使用 -W 标志。
