我尝试使用] add https://github.com/FluxML/Flux.jl，但遇到了同样的错误，有人可以帮忙吗我还尝试添加其他软件包，但是发生类似的错误，我想这可能是julia env的错误，但是不确定是否不要试图弄乱它

Answer 1

基本上，这种类型的错误要么表示您没有Internet连接（或者位于软件包管理器阻止连接的防火墙后面），要么.julia文件夹已损坏。

在第二种情况下，最容易尝试的方法是删除.julia文件夹或将系统变量JULIA_DEPOT_PATH设置为指向某个空文件夹并重新启动Julia。

错误：无法解析以下软件包名称：在Julia中安装软件包时出错
