Ruby 杰基尔服务公司'；不要开港口

在经历了很多麻烦之后，我最近安装了Jekyll，当我运行

bundle exec-Jekyll-serve

时，输出如下：

    Configuration file: /Users/Michelle/Desktop/hacked-by-chel/_config.yml
            Source: /Users/Michelle/Desktop/hacked-by-chel
       Destination: /Users/Michelle/Desktop/hacked-by-chel/_site
 Incremental build: disabled. Enable with --incremental
      Generating...
       Jekyll Feed: Generating feed for posts
                    done in 1.12 seconds.
 Auto-regeneration: enabled for '/Users/Michelle/Desktop/hacked-by-chel'
                    ------------------------------------------------
      Jekyll 4.1.1   Please append `--trace` to the `serve` command
                     for any additional information or backtrace.
                    ------------------------------------------------

它没有打开端口。 我试着运行bundle exec jekyll-service--trace，结果是

如何使Jekyll运行？

地址已在使用-绑定（2）for 127.0.0.1:4000

检查是否有任何进程使用该端口或使用其他端口：

jekyll serve --port 4001 

jekyll serve --port 4001
