安装Julia包遇到KeyError报错

Question

在服务器用Julia REPL安装第三方包ITensors的时候，收到报错

ERROR: KeyError: key "BangBang" not found

具体返回如下：

(@v1.6) pkg> add ITensors
   Resolving package versions...
ERROR: KeyError: key "BangBang" not found

我不知道报错中提到的Key是什么，在Julia第三包网站 https://julialang.org/packages/ 上查询过该名称，但觉得应该不是我要用的包。
而且我在自己电脑上安装这个包的时候没有遇到报错，但在服务器上安装的时候出现报错。但我对服务器不熟悉，不知道应该查看哪些信息，以及如何操作。
向大家请教，如何解决这个问题？

BangBang，说明缺少包或者配置写错了，检查下。
