Just as a complement to kcrisman's comment and useful links.

You need to use the package `sagetex.sty`

from the version of Sage that you are running.

To ensure the correct `sagetex.sty`

will be used, copy it to an appropriate location:
- either in the system's texmf hierarchy
- or in your local texmf hierarchy
- or next to the file you are compiling.

If you go for the last option, you could run this sequence of shell commands:

```
$ cd /working/dir/
$ SAGE_ROOT=`sage -c 'print SAGE_ROOT'`
$ cp $SAGE_ROOT/local/share/texmf/tex/generic/sagetex/sagetex.sty .
```

(this will copy the correct `sagetex.sty`

to your working directory).

Then you can run latex, sage, and latex again to process your file.

```
$ pdflatex file.tex
$ sage file.sagetex.sage
$ pdflatex file.tex
```
