我在本地计算机上运行的代码很好。我拉上我的Ubuntu服务器，运行apt-get install erlang然后尝试make run启动我的服务器。
收到错误：erlang.mk：4230：目标＆＃39; deps＆＃39;失败
我尝试删除deps文件夹（已提交）并重建：
ls deps
cowboy cowlib jiffy ranch
root@ubuntu-s-2vcpu-4gb-nyc1-01:~/keystore/sell# rm -rf deps
root@ubuntu-s-2vcpu-4gb-nyc1-01:~/keystore/sell# make run
DEP cowboy
DEP jiffy
