You have an unrelated error in your code. I would encourage you to try an example file that is very small. Save the following as test.jmd and then use the weave command with it.
# This is my document
This is some text
```julia
x = 1
print(x)
```
It’s very hard to help without more information. Additionally, I would encourage you to try harder to recognize when the error you encounter has to do with the problem you are trying to solve, and when it is an unrelated error due to a typo in your code.
