在mac上通过java运行redis时权限被拒绝

Question

我正在使用嵌入式redis项目https://github.com/kstyrc/embedded-redis 试图通过我的单元测试运行它。我在mac机器上。

我的 redis impl 位于目录：/Users/myname/servers/redis-unstable

只要我尝试运行它：

@Before
    public void init() throws IOException {     
        redisServer = new RedisServer(new File("/Users/myname/servers/redis-unstable"), 6379);   
        redisServer.start();
    }

我的权限被拒绝：

我什么都试过了.. chmod 755 chmod u+x

还是一样的错误。

有什么想法吗？

你下载后是否运行过make命令？我认为即使它是不稳定的版本，你也会寻找 redis-server 而不是 redis-unstable。
