Description

I tried to execute jupyter lite serve --pyodide=pyodide --mathjax-dir=MathJax-2.7.5 after jupyter lite init--pyodide=pyodide --mathjax-dir=MathJax-2.7.5. The init command worked, but serve command failed with the following errors.

......

TaskError - taskid:build:pyodide:copy:pyodide

    with open(src, 'rb') as fsrc:
FileNotFoundError: [Errno 2] No such file or directory: 'D:\\code\\python\\jupyterlite\\test\\.cache\\pyodide\\pyodide\\pyodide'

Reproduce

  1. unzip pyodide and mathjax to the cwd
  2. jupyter lite int --pyodide=pyodide --mathjax-dir=MathJax-2.7.5
  3. jupyter lite serve --pyodide=pyodide --mathjax-dir=MathJax-2.7.5

Expected behavior

The serve command should work.

The upstream distribution has a pydodide folder inside it, and so we preserve that it the cache, to avoid path surprises, have you tried unpacking it directly from the upstream, preserving that layer?

The alternative is to specify the path to the archive: it will only re-unpack it to the cache if the archive has changed.

I tired in another computer with relative or absolute pyodide path, It's the same error. And I also test with pyodide-build-0.19.1.tar.bz2, this works.

So the actural problem the cached pyodide path of direct provided and compressed bz2 is not matched. The compressed bz2 have a top level pyodide folder already.

But the directory of cached pyodide is too deep, In my computer, it is D:\code\python\jupyterlite\test\.cache\pyodide\pyodide\pyodide\. Maybe we should shorten it to some like D:\code\python\jupyterlite\test\.cache\pyodide\

I updated the pr, and tested with url, bz2, directory.

I confirm this is still an issue. The --pyodide argument doc claims "allows for fetching either a compressed pyodide .bz2, or folder containing such an archive’s contents." but providing a folder actually does not work with a similar error as the top message in this issue.

Here is a snippet that reproduces

# Download and extract latest pyodide release archive
wget https://github.com/pyodide/pyodide/releases/download/0.22.1/pyodide-core-0.22.1.tar.bz2
tar xvf pyodide-core-0.22.1.tar.bz2
jupyter lite build --pyodide pyodide

On the other hand providing a .tar.bz2 works fine:

jupyter lite build --pyodide pyodide-core-0.22.1.tar.bz2

jupyterlite/jupyterlite#568 was an attempt at fixing this issue but I have not managed to test it in less than 15 minutes of effort ...

Here is the traceback when trying to use --pyodide <folder>:

@lesteve I was seeing an error like this when using a directory with --pyodide too:

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/test/.cache/pyodide/pyodide/pyodide'

I found that the problem in my case was directory structure. I had the pyodide's dist in a folder like this:

foo-pyodide/pyodide.js
foo-pyodide/pyodide.asm.js
...

and was building with jupyter lite build --pyodide foo-pyodide/. The build failed with the above error.

I made a new directory foo-pyodide/pyodide/, moved the pyodide dist in there, and then again passed --pyodide foo-pyodide/. This worked as expected.

In other words, I think --pyodide expects to be pointed to a directory with a subdirectory called pyodide containing the files from the dist, not to the directory containing the dist itself.

NB: I saw the same problem when using a .tar.bz2 with the wrong directory structure too.

@tomjakubowski thanks the work-around!

Having said that it is not super intuitive and hopefully this can be improved at one point for example:

  • by improving the error message
  • by being a bit more flexible and not relying on having a nested folder called "pyodide"
