Hi,

the PythonCall.jl equivalent of [the explicit adding of `site-packages`](https://discourse.julialang.org/t/error-with-importing-matplotlib-pyplot-for-use-with-pycall-jl/124062/5) also seems to work here:

```julia
ENV["JULIA_PYTHONCALL_EXE"] = "C:/Research Software/Python/Virtual Environments/venv_1/Scripts/python.exe"
ENV["JULIA_CONDAPKG_BACKEND"] = "Null"
using Pkg
Pkg.add("PythonCall")
using PythonCall
pyimport("site").addsitedir("C:/Research Software/Python/Virtual Environments/venv_1/Lib/site-packages")
# Alternatively, pyimport("sys").path.insert(0, "C:/Research Software/Python/Virtual Environments/venv_1/Lib/site-packages") also seems to work.
# It's probably safest to add to both site and path.
Pkg.add("PythonPlot")
Pkg.add("Plots")

using Plots
pythonplot()

x = [1,2,3,4,5]
y = x

plot(x,y)
```
