Installing optional packages - infinite loop

edit

Would you mind write this up for the Sagemath Installation Guide ? The process is described in the Sage develoiper's guide. Basically, you submit a patch against the Installation Guide source. It is not supe-steamlined, but it is tolerably easy, even for dummies of my kind...

Thanks a lot for your install process ! I will add: do not forget to enable virtualization in UEFI.

For me the make command begun at 11:26 end end at at 13h15 (less than 2 hours) I did not arrive to exit edit and save after,edit ~/.bashrc ! ;-( , so I used nano ;-)

and also I encounter a problem of right of access to the W10 Documents directory

ortollj@DESKTOP-K30FLRP:~$ cd /root/mnt/c/Documents\ and\ Settings/ortollj
-bash: cd: /root/mnt/c/Documents and Settings/ortollj: Permission denied
ortollj@DESKTOP-K30FLRP:~$

I suppose I have to do something in Powershell ?

OOPS !

I was wrong about my user name W10 which is simply: user !. but now with the good user name : user, I still got the pb

ortollj@DESKTOP-K30FLRP:/$ cd /root/mnt/c/Documents\ and\ Settings/user
-bash: cd: /root/mnt/c/Documents and Settings/user: Permission denied
ortollj@DESKTOP-K30FLRP:/$

The "/root" at the beginning of the path shouldn't be there, so the command would be: cd /mnt/c/Documents\ and\ Settings/user

oops again, Sorry !

ortollj@DESKTOP-K30FLRP:/mnt/c/Documents and Settings/User$ cd ~
ortollj@DESKTOP-K30FLRP:~$ pwd
/home/ortollj
ortollj@DESKTOP-K30FLRP:~$ cd /mnt/c/Documents\ and\ Settings/user
ortollj@DESKTOP-K30FLRP:/mnt/c/Documents and Settings/user$

its ok now

Sorry but I still meet one last pb, each time I try to ./sage_nb.sh I have to make a copy paste of the http with the tocken in a browser to launch JupyterLab

Start : This command cannot be run due to the error: The system cannot find the file specified. At line:1 char:1 + Start "file:///home/ortollj/.local/share/jupyter/runtime/nbserver-141 ...

and in fact I do not actually see a file that begins with nbserver-141 but rather nbserver-1441-open.html

ortollj@DESKTOP-K30FLRP:~$ cd /home/ortollj/.local/share/jupyter/runtime
ortollj@DESKTOP-K30FLRP:~/.local/share/jupyter/runtime$ ls
nbserver-1209-open.html  nbserver-1441-open.html  nbserver-1672-open.html  nbserver-1902-open.html  notebook_cookie_secret
nbserver-1209.json       nbserver-1441.json       nbserver-1672.

I see somebody has the same pb on stackOverflow

I change my default browser by Edge en now I got :

Start : This command cannot be run due to the error: The system cannot find the file specified. At line:1 char:1 + Start "file:///home/ortollj/.local/share/jupyter/runtime/nbserver-818 ...

I succeed creating file jupyterlab --generate-config :

ortollj@DESKTOP-K30FLRP:~$ sage --notebook jupyterlab --generate-config

Writing default config to: /home/ortollj/.sage//jupyter-4.1/jupyter_notebook_config.py
ortollj@DESKTOP-K30FLRP:~$

but what does he mean by : then change the following line: c.NotebookApp.use_redirect_file = False

remove the # ? I cant put the the jupyter_notebook_config.py (not enough place) .

I put my content of jupyter_notebook_config.py in a comment on sandy_scott web site

all is ok Now !!! ;)

in the file /home/ortollj/.sage//jupyter-4.1/jupyter_notebook_config.py,as josebrwn said in stackOverflow i added the line:

#--------------------------------------------------------------
# NotebookApp(JupyterApp) configuration
#--------------------------------------------------------------
c.NotebookApp.use_redirect_file = False

and in the file ~/.bashrc I added the line, after installing Chrome Browser in W10:

export BROWSER='/mnt/c/Program Files/Google/Chrome/Application/chrome.exe'

(not Program Files (x86)/ for me,

my chrome.exe is located in Program Files/Google/Chrome/Application/)

and now when launch my windows shortcut( I named sageJupyterLab) , Jupyter_lab is lauching ;-). Thank you very much @sandy_scott

I'm glad it all worked, though I didn't see any of those issues with my installation, I was clearly very lucky.

@emmanuel-charpentier - I've made some changes to the Documentation, Trac ticket with commit attached is here: https://trac.sagemath.org/ticket/31138

I confess I was genuinely surprised at how well the WSL installation worked - I was expecting a deal-breaking issue to pop up at some point and it never did :-). I can add an issue, but my motivation for the from-source install was the same as the OP's problem - I wanted to install optional packages, in my case the jupyterlab_widgets package to get interact working in JupyterLab.

@sandy_scott there is an error in step 3, it is not :

cd /mnt/c/Documents\ and\ Settings\[your windows username]

but

cd /mnt/c/Documents\ and\ Settings/[your windows username]

like you write in step 4

in Jupyter_lab part step 5, if W10 2004, it will be not :

Change Target to: ubuntu.exe run ~/sage_nb.sh

but:

Change Target to: ubuntu2004.exe run ~/sage_nb.sh

but I think that installing again on a second PC it was due to W10 2004 and also because I use Ubuntu 20.04 for WSL (because in my previous installation on another PC Change Target to: ubuntu.exe run ~/sage_nb.sh was ok despite I use also Ubuntu 20.04 !)

W10 Ubuntu 2004
