1. Reference: Upgrading Yii Framework from version 2.0.15.1 to 2.0.31
2. Errors occurred in some programs using: \GuzzleHttp\json_encode, \GuzzleHttp\json_decode. After final analysis, the reason is that the directories: /vendor/guzzlehttp/guzzle, /vendor/guzzlehttp/promises no longer exist. See Figure 1.
3. After careful analysis, I found that in step 2 of the referenced URL, running composer update uninstalled: guzzlehttp/promises, guzzlehttp/guzzle, as shown in Figure 2.
4. The issue in step 2 was ultimately resolved by using the Yii helper class Json: https://www.yiiframework.com/doc/api/2.0/yii-helpers-json, performing the corresponding replacement operations.
\GuzzleHttp\json_decode
\yii\helpers\Json::decode
\GuzzleHttp\json_encode
\yii\helpers\Json::encode
5. In a branch where the Yii 2 version is still 2.0.15.1, using the dependency check depends command can determine whether a package installed in your project is being depended on by other packages, and lists them. The conclusion: guzzlehttp/promises depends on guzzlehttp/guzzle, guzzlehttp/guzzle depends on codeception/base, and codeception/base depends on yiisoft/yii2-app-advanced. See Figure 3.

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

shuijingwan/yii2-app-advanced dev-feature-config-group-task-step requires (for development) codeception/base (^2.2.3)
6. After checking the composer.json of two versions of codeception/base respectively, upgrading Yii Framework from version 2.0.15.1 to 2.0.31 consequently caused codeception/base to upgrade from version 2.5.2 to 2.5.6, and version 2.5.6 of codeception/base has already abandoned the dependency on guzzlehttp/guzzle. Observation shows that the dependency type of codeception/base is: require-dev, therefore, it can only be used in the development stage, not in the production stage.
"require-dev": {
"yiisoft/yii2-debug": "~2.0.0",
