__dirname is not defined in es module scope

这个问题是在 ES 模块作用域下,指向当前模块所在目录的 __dirname 变量未定义的错误。可以使用 import.meta.url 来获取当前模块的文件路径,再使用 path 模块来解析出相应的目录信息。

__dirname is not defined
__ is not defined in ES module scope 这个错误是因为在ES模块中,没有内置的__dirname变量。在CommonJS模块中使用__dirname是可以的,但在ES模块中,要获取当前模块文件所在的目录路径可以使用其他方法。
一个可行的方法是使用import.meta.url和fileURLToPath方法来获取当前模块文件的路径,然后通过path.dirname方法来获取所在目录的路径。
示例代码如下:
```javascript
import { fileURLToPath } from 'url';
import { dirname } from 'path';
const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);
```
这样就可以在ES模块中获取到当前模块文件所在的目录路径了。
_dirname is not defined
As an AI language model, I am unable to determine the exact context of your issue. However, the error message "_dirname is not defined" usually occurs when the variable "_dirname" is used in a JavaScript file, but it is not defined or declared anywhere in the file.
"_dirname" is a special global variable in Node.js that stores the path of the directory where the current JavaScript file is located. If you are trying to use this variable in a browser environment or outside of a Node.js environment, it will not be available.
To resolve this issue, you need to make sure that you are using the "_dirname" variable in a Node.js environment and that it is properly defined and declared in your code.
