# missing key "SAGE_LOCAL" while "import sage.all"

Hello I tried to do some debugging in PyDev. I haven't done any math there yet, just tried to import sage.all and failed.

Variable sage.env.SAGE_LOCAL is "/usr/lib/sagemath//local", so maybe OK, maybe not. I don't know where this double slash comes from.When I write $SAGE_LOCAL in bash, I get "/usr/lib/sagemath/local"

This is my sage.env.SAGE_ENV:

```
{'SAGE_LOCAL': '/usr/lib/sagemath//local', 'SAGE_IMPORTALL': 'yes', 'SITE_PACKAGES': ['/usr/lib/sagemath/local/lib/python2.7/site-packages', '/usr/lib/sagemath/local/lib/site-python'], 'SAGE_BANNER': '', 'TRAC_SERVER_URI': 'https://trac.sagemath.org', 'SAGE_EXTCODE': '/usr/lib/sagemath//local/share/sage/ext', 'SAGE_CYTHONIZED': '/usr/lib/sagemath//src/build/cythonized', 'SAGE_DOC_SRC': '/usr/lib/sagemath//src/doc', 'SAGE_ETC': '/usr/lib/sagemath//local/etc', 'SAGE_REPO_AUTHENTICATED': 'ssh://git@trac.sagemath.org:2222/sage.git', 'SAGE_STARTUP_FILE': '/home/a/.sage/init.sage', 'SAGE_DOT_GIT': '/usr/lib/sagemath//.git', 'UNAME': 'Linux', 'SAGE_SHARE': '/usr/lib/sagemath//local/share', 'PYTHON_EGG_CACHE': '/home/a/.sage/.python-eggs', 'SAGE_SPKG_INST': '/usr/lib/sagemath//local/var/lib/sage/installed', 'SAGE_REPO_ANONYMOUS': 'git://trac.sagemath.org/sage.git', 'SAGE_DOC': '/usr/lib/sagemath//local/share/doc/sage', 'SAGE_VERSION': '7.3', 'REALM': 'sage.math.washington.edu', 'SAGE_INC': '/usr/lib/sagemath//local/include', 'SAGE_DATE': '2016-08-04', 'SAGE_SRC': '/usr/lib/sagemath//src', 'SAGE_LIB': '/usr/lib/sagemath/local/lib/python2.7/site-packages', 'SAGE_DISTFILES': '/usr/lib/sagemath//upstream', 'LOCAL_IDENTIFIER': 'a-GA-970A-DS3.7845', 'SAGE_ROOT': '/usr/lib/sagemath/', 'HOSTNAME': 'a-GA-970A-DS3', 'SAGE_URL': 'http://sage.math.washington.edu/sage/', 'DOT_SAGE': '/home/a/.sage', 'SAGE_LOGS': '/usr/lib/sagemath//logs/pkgs'}
```

However SAGE looks for this variable in some dictionary that looks like this (my system variables):

```
{'PYTHONIOENCODING': 'UTF-8', 'LIBOVERLAY_SCROLLBAR': '0', 'XDG_RUNTIME_DIR': '/run/user/1000', 'XDG_CURRENT_DESKTOP': 'KDE', 'XDG_SESSION_TYPE': 'x11', 'QT_IM_MODULE': 'compose', 'LOGNAME': 'a', 'USER': 'a', 'HOME': '/home/a', 'XDG_VTNR': '7', 'PATH': '/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/lib64/MRO-3.2.3/R-3.2.3/lib/R:/home/a/anaconda2/bin', 'PYTHONUNBUFFERED': '1', 'PAM_KWALLET_LOGIN': '/tmp/kwallet_a.socket', 'KDE_SESSION_VERSION': '5', 'KDE_FULL_SESSION': 'true', 'XDG_SESSION_DESKTOP': 'KDE''...}
```

Last instruction is

```
from . import matrix_mpolynomial_dense in matrix_space.py
```

Before:

```
else:
from sage.matrix.matrix_space import is_MatrixSpace
```

( in definition of class class PolynomialRing_general(sage.algebras.algebra.Algebra in polynomial_ring.py)

And it all started with

```
from sage.rings.all import *
```

in all.py

Full traceback looks like this (don't think it's useful):

```

Can you tell us in which context you need this? Your title has an error message in it but you don't say what gives that error, which could be really useful for helping.

Thanks for answer. I have added some information. All I tried to do was to import sage.all I have added some information. My guess is that Sage gathers my system variable but doesn't take SAGE_LOCAL (maybe because of double slash, maybe not). Nevertheless in notebook it works OK.

You probably need your IDE or whatever to not just import sage.all, but to set all such variables properly - typically this is done by running

`sage -sh`

which sets all env vars correctly. I'm not familiar with PyDev so I don't know what the equivalent would be there. The Sage notebook does all this on its own, of course.yeah! You solved my problem. It's enough to run bash in LiClipse's folder, run "sage -sh" and from this shell run LiClipse (or Eclipse if you like). Thank you. You can add answer, if You like. I think many people can have this problem, since old tutorials say just "import sage.all".

Can you say in which tutorials? I don't use these systems myself, but we should fix them if they are live documentation.
