"] activate ./" required before “] status” in the "1. Environment setup.ipynb" about dataframes HOT 4 CLOSED

Thank you for reporting this. It seems to be a problem with nteract as what I use follows the specification how things should work https://github.com/JuliaLang/IJulia.jl#julia-projects (and they work this way for me).

Before we move forward - please confirm that you start Jupyter Notebook in the directory where Project.toml is located (I assume yes). If this is the case then I will report the issue in https://github.com/JuliaLang/IJulia.jl.

CC @stevengj as you maybe know about this issue already.

You are welcome. I did more tests just now to reproduce this issue:

• Step 1: Download the "1. Environment setup.ipynb" from the link below the tutorial video on JuliaAcademy and put it under "./Introduction to DataFrames.jl/"
• Step 2: Double-click to run the notebook with nteract. (At this time, the Project.toml file doesn't exist. The folder only contains one notebook file.)
• Step 3: Yesterday when I reached "isfile.(["Project.toml", "Manifest.toml"])" I realized I need these two files from GitHub. So I downloaded as zip archive and extracted the files to the same folder where the "1. Environment setup.ipynb" from Step 1 located. (At this time, the "1. Environment setup.ipynb" was still open in nteract.)
• Step 4: Run "isfile.(["Project.toml", "Manifest.toml"])" to get two 1s.
• Step 5: Run "] status" to get "~/.julia/environments/v1.4/Project.toml" checked instead of the "./Introduction to DataFrames.jl/Project.toml"

I tried to run the same notebook with Project.toml already exists in the same folder. It correctly recognized the path "./Introduction to DataFrames.jl/Project.toml" without an issue.

I guess IJulia has a mechanism to look for Project.toml file in the same folder as the notebook first, if it doesn't exist, then fallback to the default Julia path.

If this is true, then this issue can be avoided if a student clones all notebooks and toml files from GitHub directly instead of just download one notebook from JuliaAcademy. Or just add "] activate ./" before “] status” as a safe net.

So - you are correct. Project.toml is looked for when you start the notebook. A standard procedure is - as you indicated - to clone the whole repository first (rather than downloading a single file). I will update README.md to highlight that.

Thank you professor! 👍
