    <p><strong>Edit:</strong> looks like pip is to blame but not sure how to fix it</p> <hr> <p>I seem to be having a bit of problem with my Python 2.7 installation. Ever now and then for no obvious reason previously working imports of modules like the one below stop working. </p> <pre><code>&gt; import networkx Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; ImportError: No module named networkx </code></pre> <p>After doing some digging I found the output fro <code>print sys.path</code> to be much sparser than expected (sorry don't have the output, will update next time it happens). As far as I remember it has no 'site--packages' &amp; egg's from 'site-packages'.</p> <p>The only way I have found to fix this is to re-run the installer and "repair" Python. This has become tiresome and I would like to find the root cause of this. </p> <ol> <li><strong>Has anyone experiences this problem before? How did you resolve it</strong></li> <li><strong>What can I do to trace the cause of this issue?</strong></li> </ol> <hr> <p><strong>Update 1</strong> This is the output of <code>sys.path</code> when this problem happens</p> <pre><code>['', 'C:\\Windows\\system32\\python27.zip', 'C:\\Python27\\Lib', 'C:\\Python27\\DLLs', 'C:\\Python27\\Lib\\lib-tk', 'c:\\Python27', 'd:\\dev\\bin'] </code></pre> <hr> <p><strong>Update 2</strong> Happened again, this time I took a copy of the python27 folder, ran the fix (aka repair the install) then did a diff over the files to see if there was any differences. There was nothing different. Also checked the <code>HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.7</code> keys for anything strange. There is a value for <code>PythonPath</code> but that does not seem to have any issue with it. Will check next time.</p>

    1. CO`echo $PYTHONPATH` would be a start. Likely, some setting in your environment is off.

    2. COif you have multiple versions of python installed - could be a problem. what is the problem with simply running `print sys.path` in the interpreter right now and putting that here?

    3. COI've just 'fixed' the issue again so only have the output of when it's not broken. %PYTHONPATH% (I'm on windows) is empty. Yes do have multiple versions installed however only been using 2.7 recently.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
