 "response": {
   "description": "The error message indicates that the version string specified in your `composer.json` file is invalid. The version string should follow a specific format, typically something like 'x.y.z' where x, y, and z are integers or you can use wildcards for more flexibility (e.g., '^1.0', '>=2.0').",
   "solution": {
     "step_1": "Open your `composer.json` file.",
     "step_2": "Locate the line that specifies the version of `alibabacloud/cloudauth`. It should look something like this: `\"alibabacloud/cloudauth\": \"^2.0\"` or similar, ensuring there are no extra spaces around the version number.",
     "step_3": "If you intended to specify a specific version and accidentally included an invalid character (like a space), remove it from your version string. For example: `\"alibabacloud/cloudauth\": \"2.0.5\"`",
     "step_4": "Save the `composer.json` file.",
     "step_5": "Run the command again: `composer require alibabacloud/cloudauth-20200618`"
   },
   "note": "Make sure to replace '2.0' with the actual version you intend to use, following semantic versioning rules (major.minor.patch). If you are unsure about which version to specify, you can often find this information in the repository or documentation for the package."
