观察：
日期及其相关程序包只有一个uuid，如下所示：
"/opt/julia/julia-1.1.0/share/julia/stdlib/v1.1/Dates/Project.toml"
name = "Dates"
uuid = "ade2ca70-3891-5945-98fb-dc099432e06a"
...
及其相关的软件包：
"/opt/julia/julia-1.1.0/share/julia/stdlib/v1.1/<PACKAGE_NAME>/Project.toml"
...
[deps]
...
Dates = "ade2ca70-3891-5945-98fb-dc099432e06a"
...
请帮助我解决Pkg的重复密钥问题！
