Question

我在我的一个项目中使用gulp。从OS（Arch Linux）运行gulp watch时

fs.js:921
  return binding.readdir(pathModule.toNamespacedPath(path), options.encoding);
             ^

Error: EACCES: permission denied, scandir '/tmp/systemd-private-c33e4391b18f4b24af3055190fb15730-systemd-hostnamed.service-zrxyaX/'

我从主机操作系统运行gulp而不是虚拟机，因为它更快。

我理解问题是gulp正在主机操作系统的/tmp文件夹中执行某些操作，而某些文件具有root权限。

如果我运行sudo chown -R majmun:users /tmp，之后会出现具有root权限的新文件，这会破坏gulp。

为什么gulp watch需要/tmp个文件夹。有人解决了这个问题吗？

这是gulp watch任务的代码 // gulp watch

 Gulp.task('watch', ['dev'], function() {
        console.log('Initializing assets watcher:')

    let stream = new Stream();
    let filter = '*.{css,scss,sass,less,js,png,jpg,jpeg,svg}';
    let tmp = Tmp.fileSync();
    let glob = [
        path.src.assets + '**/' + filter,
        path.src.elements + '**/' + filter,
        path.src.properties + '**/' + filter,
    ];

    for (let i = 0; i < glob.length; i++) {
        console.log('- ' + glob[i]);
    }

    let watcher = Gulp.watch(glob, ['dev']);
    watcher.add(tmp.name);

    process.on('SIGINT', function() {
        stream.emit('end');
        process.exit(0);
    });

    KeyPress(process.stdin);
    process.stdin.on('keypress', function(char, key) {
        if (key && key.ctrl && key.name == 'c') {
            process.emit('SIGINT');
        }
        else if (key && key.ctrl && key.name == 'r') {
            Fs.utimes(tmp.name, new Date(), new Date(), function() {});
        }
    });
    process.stdin.setRawMode(true);
    process.stdin.resume();

    console.log('Watcher up and running, Ctrl+R to refresh, Ctrl+C to exit.');
    return stream;
});

我通过使用tmp库添加一些选项来解决此问题。我指定了临时文件夹的位置及其权限，而不是默认选项。

所以代替这个：

let tmp = Tmp.fileSync();

我这样做了：

let tmp = Tmp.fileSync({ 
    // Use settings from .env if defined 
    dir: process.env.MY_TMP_DIR || ''
    mode: process.env.MY_TMP_MODE || '', 
    prefix: process.env.MY_TMP_PREFIX || '', 
});

Gulp watch / tmp权限被拒绝
