SageMath doesn't pass all tests

[Taj Jankovic]

Hi everyone,

I am having trouble with the SageMath. 

1/ I've downloaded the binary tar file sage-9.1-Ubuntu_18.04-x86_64.tar.bz2 from
https://www.sagemath.org/download-linux.html

2/ Then
tar jxvf sage-9.1-Ubuntu_18.04-x86_64.tar.bz2
cd SageMath
./sage -tp --long src/sage/manifolds

However, instead of "All tests passed!", I get a multitude of errors. 

-a typical error is:

sage -t --long src/sage/manifolds/utilities.py

I am using Ubuntu 18.04 LTS and have Python 2.7, 3.6, and 3.7 installed. Does anyone maybe have an idea of what could be causing these errors? Any help is very much appreciated.

Best regards,

at this point one should run

./sage

without parameters.
Only then it should be ready (the 1st run is a kind of bootstrap)

Also, if it helps, if I follow these steps

cd /home/taj/SageMath
./sage


and run the command
sage: assume(x<1)




I get a similar error

it might be quicker to build Sage from source on your system than to try to fix this.

Hi all,

building Sage from the source was also unsuccessful. However, I resolved the issue by uninstalling tex-live and all related packages. Then I was able to normally extract the SageMath binary and all tests passed without errors.

Thanks again for all the help!

Best,

Taj

I have TeXstudio, I get the same issue of all test not passed. May I should also try for reinstalling Texstudio, right?

Thanks for letting us know. I must say I don't recall texlive
installing ecl, but perhaps that's what happened in your case.
It would be interesting to know which ubuntu package does this.

It is hard to say without knowing what kind of errors you see.
