Error information is not easy to follow, no error location in the user source code #35528

The error information is not as clean as that of Python. In the Python language, when there is error it is quite easy to find the location from the error information. Is it possible to make the error information clean, short and helpful as Python Language. |

This would be caused by error in `` of Pkg. (Hotspot) pkg> instantiate |
When run
testusing Pkg and encounter an error in the code, the location of the error in the source code written by user cannot be found. It cost user extra time to guess the location of the error. The error information is as following.(Hotspot) pkg> test ERROR: MethodError: no method matching joinpath(::Nothing) Closest candidates are: joinpath(::String, ::String) at path.jl:265 joinpath(::AbstractString) at path.jl:247 joinpath(::AbstractString, ::AbstractString) at path.jl:274 ...
