Promise.all().then() - then()在all()完成之前执行

在gulp任务中,我有以下代码创建一个gitAction promises数组,它在一个Promise.all()语句中执行.之后,我正在进一步发表声明then().但是在then()git拉入all()之前被调用已经终止.请问有什么线索吗？

var git = require('gulp-git');
var gitActionPromise = function(repo, url) {
    console.log('git action '+repo);
    var pathToRepo = './repos/'+repo;

    if (fs.lstatSync(pathToRepo).isDirectory()) {
        return new Promise((resolve, reject) => {
            git.pull('origin', 'master', {cwd: pathToRepo}, function (err) {
                console.log(repo + " pull done!");
                if (err) {
                    console.log('error');
                    reject(err);
                } else {
                    console.log('ok');
                    resolve();
                }
            })
        })
    } else {
        return new Promise((resolve, reject) => {
            git.clone(url, {cwd: pathToRepo}, function (err) {
                console.log(repo + " clone done!");
                if (err) {
                    console.log('error');
                    reject(err);
                } else {
                    console.log('ok');
                    resolve();
                }
            })
        })
    }
};

var repos = package.repos || {};
var promises = Object.keys(repos).map(function(repo) {
    return gitActionPromise(repo, repos[repo]);
});

Promise.all(promises).then(
    console.log('something else')   <= this line was causing my issue
);                                     needed to be enclosed in function

你必须将一个函数传递给then:

Promise.all(promises).then(function() {
    console.log('something else');
});

您只需立即记录"其他内容"即可.
