When i follow the tutorial on:

> **[GitHub - dynamicslab/NormalFormAE](https://github.com/dynamicslab/NormalFormAE)**

> Contribute to dynamicslab/NormalFormAE development by creating an account on GitHub.

I run

> julia -i run/run\_nf.jl

And I obtain the following error:

> shell\> julia -i run/run\_nf.jl  
> /usr/share/modules/init/bash: eval: line 43: syntax error near unexpected token `(' /usr/share/modules/init/bash: eval: line 43: ` Pkg.precompile() \_mlshdbg=‘’ ;;’

Please don’t double-post. The answer is in [Dependencies "4 skipped during auto due to previous errors"](https://discourse.julialang.org/t/dependencies-4-skipped-during-auto-due-to-previous-errors/79862)
