基于 Composer 更新 Yii 2 至最新版本后，软件包：guzzlehttp guzzle 的丢失的分析

1、参考网址：https://www.shuijingwanwq.com/2020/01/19/3869/ ，将 Yii Framework 从 2.0.15.1 版本升级到 2.0.31

2、在一些使用了：\GuzzleHttp\json_encode、\GuzzleHttp\json_decode 的程序中报错，最终分析发现，原因在于，目录：/vendor/guzzlehttp/guzzle、/vendor/guzzlehttp/promises 已经不存在。如图1

图1

3、仔细分析后，发现参考网址中的第 2 个步骤，运行 composer update 时，卸载了：guzzlehttp/promises、guzzlehttp/guzzle，如图2

图2

4、步骤 2 的问题，最终通过 Yii 帮助类 Json： https://www.yiiframework.com/doc/api/2.0/yii-helpers-json 得以解决，执行相应的替换操作

\GuzzleHttp\json_decode
\yii\helpers\Json::decode

\GuzzleHttp\json_encode
\yii\helpers\Json::encode

5、在一个 Yii 2 版本仍然为：2.0.15.1 的分支中，使用 依赖性检测 depends 命令可以查出已安装在你项目中的某个包，是否正在被其它的包所依赖，并列出他们。得出结论：guzzlehttp/promises 依赖于 guzzlehttp/guzzle，guzzlehttp/guzzle 依赖于 codeception/base，codeception/base 依赖于 yiisoft/yii2-app-advanced。如图3

To see the help of each command, enter:

  yii help <command-name>

PS E:\wwwroot\pcs-api-feature-config-group-task-step> composer depends guzzlehttp/promises
guzzlehttp/guzzle  6.3.3  requires  guzzlehttp/promises (^1.0)
PS E:\wwwroot\pcs-api-feature-config-group-task-step> composer depends guzzlehttp/guzzle
codeception/base  2.5.2  requires  guzzlehttp/guzzle (>=4.1.4 <7.0)
PS E:\wwwroot\pcs-api-feature-config-group-task-step> composer depends codeception/base
shuijingwan/yii2-app-advanced  dev-feature-config-group-task-step  requires (for development)  codeception/base (^2.2.3)

6、分别查看 codeception/base 的两个版本的 composer.json，Yii Framework 从 2.0.15.1 版本升级到 2.0.31，进而导致 codeception/base 从版本 2.5.2 升级到 2.5.6，而 codeception/base 的版本 2.5.6 已经放弃依赖 guzzlehttp/guzzle。观察可发现，codeception/base 的依赖类型为：require-dev，因此，其仅能够用于开发阶段，而不能够用于生产阶段。

    "require-dev": {
        "yiisoft/yii2-debug": "~2.0.0",
        "yiisoft/yii2-gii": "~2.0.0",
        "yiisoft/yii2-faker": "~2.0.0",
        "codeception/base": "^2.2.3",
        "codeception/verify": "~0.3.1"
    },
