ERROR: LoadError: syntax: invalid interpolation syntax: "$\"

The `d$` in the path is a problem.

Start with the Conda entry points shown in .julia\packages\Conda\...\deps\deps.jl and src\Conda.jl, then reproduce the build using a Windows path containing d$. Trace how that path is written into the generated Julia expression; done means PyCall builds successfully without the invalid interpolation syntax error.
