Error when trying to acces parent folder in Electron/Node.js

Question

I'm trying to check whether a path in a parent directory is a file or a directory.

My file system looks like this:

• files/
  • html/
    • index.html
  • javascript/
    • index.js
  • test/
    • test.jpg

Electron is started from the parent directory of files/. My code in the index.js file:

console.log(`file://${__dirname}/../test/test.jpg`);
console.log(fs.lstatSync(`file://${__dirname}/../test/test.jpg`).isFile());

When I start Electron I get two messages in the log. The first one is the path of the picture I want to access (test.jpg). When I paste this path into my browser, the picture is shown, so it is the correct path. But the second message is an error:

Uncaught Error: ENOENT: no such file or directory, lstat

And then the same path in single quotation marks ('').

I used to have the index.js and the index.html file in the same path from which electron is started from (parent folder of files/) and it worked, so I guess that it has problems accesing a parent folder. How can I solve this?

Node fs模块使用文件路径而不是URL，因此您需要将有效路径传递给fs.lstatSync ：

fs.lstatSync(`${__dirname}/../test/test.jpg`).isFile()
