Invalid package.json name

当出现 "Invalid package.json name" 错误时，通常是因为 package.json 文件中的 "name" 字段的值不符合规范。

根据 npm 的官方规范，package.json 中的 "name" 字段应该符合以下要求：

- 只能包含小写字母、数字、连字符（-）或下划线（_）
- 不能以连字符或下划线开头或结尾
- 不能包含空格或特殊字符

请确保 package.json 文件中的 "name" 字段符合上述规范。以下是一个示例的有效 "name" 字段值：

"name": "my-project"

如果你的 "name" 字段符合规范，但仍然遇到该错误，请检查其他可能导致问题的地方，例如文件路径、文件内容等。

另外，你还可以尝试删除 package.json 文件中的 "name" 字段，然后重新运行相关命令，让 npm 自动生成一个符合规范的 "name" 字段值。

如果问题仍然存在，请提供更多详细信息，以便我能够更准确地帮助你解决问题。

Please verify that the package.json has a valid "main" entry

The "main" entry in package.json specifies the main entry point of the package. This is the file that will be loaded when the package is required or imported. To verify that the package.json has a valid "main" entry, you can open the file and check that the "main" field is present and points to a valid file path.

For example, if your package has a file called "index.js" that serves as the main entry point, your package.json should have the following field:

{
  "name": "my-package",
  "version": "1.0.0",
  "main": "index.js"
}

This tells Node.js to load "index.js" when the package is required.

If the "main" entry is missing or points to an invalid file path, you may encounter errors when trying to import or require the package.

An unexpected error occurred: "C:\\Users\\86137\\Desktop\\block-design-jeecg\\package.json: Unexpected token / in JSON at position 2589".

问题产生的原因是JSON文件中出现了不符合JSON格式的字符，导致解析失败。解决方法是找到该位置并进行修改。可以使用一些在线JSON格式化工具来帮助定位问题所在。

  "name": "example",
  "version": "1.0.0",
  "description": "example project",
  "main": "index.js",
