I would like to add Maxima.jl, but in order to run Maxima I need to add a directory to the Path environment, so Julia can find it.

```julia
On Windows you will also need to add the directory containing the maxima.bat executable to your PATH environment variable so that Julia can find it.

```

How do I do this?

This is for python, but the instructions on adding a directory to path is the same. You’ll need to add the directory that contains `maxima.bat` rather than the python executables though

Am I looking for a Windows Bash file, and expected to put a link to that directory? What about variable name?

You’ll need to add the `bin` folder of maxima to path. as described in [Maxima – Installation in Windows](http://maxima.sourceforge.net/windows-install.html)

Cool it works 🕶 I can get into the Maxima REPL. The only thing I’m not sure of is how to access Maxima from the Julia REPL, or from Julia Markdown. I think I’ll go check the docs for a macro.

@brett_knoss Saying “it won’t load” is not useful. Please show a minimal example of the file you are trying to run and the complete error message produced.

I’ll send a screenshot in a second, but basically it says Weaving chunk 1(or whatever chunk has

```julia
using Maxima

```

in output. It doesn’t ever stop or give an error warning.

I’m updating everything, and right now Weave won’t do anything.

Have you tried running weave from a standard Julia repl? What happens?
