fs-extra：错误：EPERM：不允许操作，取消链接

Question

I am receiving the following error using fs-extra :

ERROR { [Error: EPERM: operation not permitted, unlink 'C:\\Projects\\xxx\\branches\\xxx\\release'] errno: -4048, code: 'EPERM', syscall: 'unlink', path: 'C:\\Projects\\xxx\\branches\\xxx\\release' }

When using this code in my node application:

const fse = require('fs-extra');
fse.copySync('../util/various/a.html', '../release');
fse.copySync('../util/various/b.html', '../release');

I would like to know, what could cause the error and how to fix it.

Answer 1

fs-extra doesn't support copying a file to a directory.

This will work:

const fse = require('fs-extra');
fse.copySync('../util/various/a.html', '../release/a.html');
fse.copySync('../util/various/b.html', '../release/b.html');

This is as-designed ( https://github.com/jprichardson/node-fs-extra/issues/320 ) although I am here because I ran into the same issue.

Answer 2

由于文件的权限，该模块无法删除目标文件（只读）。
