回答by Raghavendra
You cannot delete a directory that is not empty. And fs.unlinkSync() is used to delete a file not a folder.
您不能删除非空目录。fs.unlinkSync() 用于删除文件而不是文件夹。
To remove an empty folder, use fs.rmdir()
要删除空文件夹，请使用 fs.rmdir()
to delete a non empty folder, use this snippet:
要删除非空文件夹，请使用以下代码段：
var deleteFolderRecursive = function(path) {
if( fs.existsSync(path) ) {
fs.readdirSync(path).forEach(function(file) {
var curPath = path + "/" + file;
if(fs.lstatSync(curPath).isDirectory()) { // recurse
deleteFolderRecursive(curPath);
} else { // delete file
fs.unlinkSync(curPath);
}
});
fs.rmdirSync(path);
}
};
Snippet from stackoverflow: Is node.js rmdir recursive ? Will it work on non empty directories?
来自 stackoverflow 的片段：node.js rmdir 是递归的吗？它可以在非空目录上工作吗？

Maybe the Pathof the file is located is erroneus.
也许文件所在的路径是错误的。
if not, try with fs.unlinkSync()
如果没有，请尝试使用fs.unlinkSync()

Yes, you don't have permission to delete/unlink that file. Try again with more rights or verify that you're giving it the right path.
是的，您无权删除/取消链接该文件。使用更多权限重试或验证您提供的路径是否正确。
