typeerror: compilation.templatesplugin is not a function

这个错误提示意思是：类型错误：compilation.templatesplugin 不是一个函数。

这个错误通常出现在使用 webpack 进行编译时，可能是因为在 webpack 配置文件中使用了一个不正确的插件或者插件配置有误。建议检查 webpack 配置文件中的插件配置，确保插件名称和配置正确无误。

ERROR Build failed with errors. TypeError: compilation.templatesPlugin is not a function

抱歉，这个错误是由于编译过程中出现了问题导致的。根据错误提示，似乎是编译过程中使用了一个不是函数的模板插件。这可能是由于插件配置的问题或者版本不兼容导致的。

解决这个问题的方法可能是检查编译配置文件，确保插件的配置正确并且插件版本兼容。如果使用的是第三方插件，可以尝试更新插件版本或者寻找其他替代方案。

如果问题仍然存在，我建议您查看详细的错误日志或者与开发团队进行沟通，以便更好地解决这个问题。

data.reduce is not a function TypeError: data.includes is not a function

The error message you received suggests that `data` does not have a `reduce` or `includes` function.

Firstly, make sure that `data` is actually an array because both `reduce` and `includes` are array methods. You can check its type using `Array.isArray(data)`.

If `data` is indeed an array, then the error might be occurring because you are trying to call these methods on an undefined or non-array value within the array. In such cases, you should check if the specific element you are trying to call `reduce` or `includes` on exists and is of the expected type.

For example, you could use `Array.prototype.filter` to remove any undefined or non-array elements from `data` before using `reduce` or `includes` on it:

const validData = data.filter(element => Array.isArray(element));

Then, you can apply the desired methods on the filtered `validData` array. Remember to handle the case when `validData` is empty or doesn't contain the expected values.

If the issue persists, please provide more context or code snippets so that I can better understand the problem and assist you further.
