JULIA_PROJECT and julia --project

General Usage
1

I was just reading the documentation for Pkg.activate. Using the JULIA_PROJECT environment variable works as expected, and Julia activates the specified project. But the --project command line argument does not seem to work at all. If I provide the path that I used for JULIA_PROJECT as the argument to --project, I get:

ERROR: could not open file /Users/dmatz/Data/Julia/TrickData.jl/
Stacktrace:

 [4] exec_options(::Base.JLOptions) at ./client.jl:229
 [5] _start() at ./client.jl:421

Am I just misunderstanding --project, or is this a bug?

Could you show the command you use to start julia?

Sure.

$ pwd
/Users/dmatz/Data/Julia
$ julia --project TrickData.jl

try julia --project=TrickData.jl

Yes, that works. Why I didn’t think to try that, I don’t know… Thank you!
