I would like to use PythonPlot.jl with the QT backend. But how can I install it? I tried:

```julia
using CondaPkg
# press ]
(Climate) pkg> conda add pyqt5

```

which doesn’t work, it cannot find the package:

```julia
error libmamba Could not solve for environment specs
    The following package could not be installed
    └─ pyqt5 * does not exist (perhaps a typo or a missing channel).

```

Any idea?

```julia

pkg> conda add pyqt

```

Or

```julia
pkg> conda add anaconda::pyqt

```

?

If I do:

```julia
mkdir test
cd test
julia --project="."

```

and then

```julia
# press ]
add CondaPkg
# press <backspace>
using CondaPkg
# press ]
conda add pyqt
add PythonPlot
# press <backspace>
using PythonPlot

```

I get the error:

```julia

```

Any idea?

So I could install pyqt, but it does not work together with PythonPlot …
