Betreff: [Bioc-devel] jupyter installation on merida1

Dear BioConductor maintainers, 

The buildbots almost seem able to build my package’s vignettes again, but the 
jupyter installation on merida1 still doesn’t seem quite right: 
http://bioconductor.org/checkResults/release/bioc-LATEST/destiny/merida1-buildsrc.html

* creating vignettes ... ERROR
--- re-building ‘DPT.ipynbmeta’ using nbconvert
Warning in system2("jupyter", shQuote(args), carg, carg, wait = TRUE, env = 
env, :
running command 'PYTHONPATH=.:.: 'jupyter' 'nbconvert' [...] 'DPT.ipynb' 2>&1' 
had status 126
Call failed. Output:
sh: /usr/local/bin/jupyter: /usr/local/opt/python3/bin/python3.6: bad 
interpreter: No such file or directory

Exit status 126 means “The thing you tried to execute is not executable or 
doesn’t exist”. The message looks like sh tries to find the binary referenced 
in the shebang of /usr/local/bin/jupyter, and fails. I assume jupyter has been 
installed with an interpreter that no longer exists, and now its shebang points 
into the void? I guess the following is true for your system:

$ head -n1 /usr/local/bin/jupyter
#!/usr/local/opt/python3/bin/python3.6
$ ls /usr/local/opt/python3/bin/python3.6
No such file or directory (os error 2)

Anyway, it would be amazing if someone could fix jupyter’s installation on that 
system (until jupyter nbconvert --help works). The vignette engine trying to 
use it (nbconvertR) has extensive INSTALL instructions that might help: 
https://cran.rstudio.com/web/packages/nbconvertR/INSTALL

Thank you so much,
Philipp
