hello, when i try to run sage i have got following response:

Traceback (most recent call last):
  File "/opt/sagemath-8.3/src/bin/sage-ipython", line 9, in <module>
    from sage.misc.banner import banner
  File "/opt/sagemath-8.3/local/lib/python2.7/site-packages/sage/misc/", line 16, in <module>
  File "/opt/sagemath-8.3/local/lib/python2.7/site-packages/sage/", line 186, in <module>
    "libSingular not found--a working Singular install in $SAGE_LOCAL "
RuntimeError: libSingular not found--a working Singular install in $SAGE_LOCAL is required for Sage to work

Maybe I am wrong but i think it is caused by environment variables. Is there any easy way to fix it? I didn't get any error or warning during installation. Thanks for any reply!

What operating system and what version of it? What version of Sage? How was Sage installed? How are you running Sage?

In the shell, what does echo $SAGE_ROOT output? What about echo $SAGE_LOCAL? Did you install to the default location? Beyond that it's hard to say what the problem is. Try reinstalling.
