Ich habe diesen Befehl unter Ubuntu 14.04 Linux ausgeführt, während ich versucht habe, ein Paket zu installieren:
export PYTHONPATH=/usr/local/lib/python2.7/ && sudo python setup.py install
Das Paket, das ich installieren wollte, isthttp://github.com/ewels/MultiQC
Seitdem sind viele Dinge im Zusammenhang mit Python schiefgelaufen. Beispielsweise funktioniert virtualenv nicht mehr und dieses Paket funktioniert auch nicht:

Wie kann ich dies auf den Stand vor dem Ausführen dieser Befehlszeile zurücksetzen? Selbst wenn ich von einem neuen Bash-Terminal aus starte, findet es jetzt keine meiner anderen Python-Bibliotheken. Selbst mit einem neu erstellten Linux-Benutzer auf demselben Computer sind die Fehler dieselben.

[BEARBEITEN]
Ich weiß nicht, wie ich zur vorherigen Ordnerliste zurückkehren kann, aber ich nehme an, es war eine Kombination aus /usr/lib/python2.7 und /usr/local/lib/python2.7
Der Versuch mit virtualenv schlägt jetzt auch fehl:
virtualenv
Fatal Python error: Py_Initialize: Unable to get the locale encoding
File "/usr/lib/python2.7/encodings/__init__.py", line 123
raise CodecRegistryError,\
^
SyntaxError: invalid syntax

Interaktives Python funktioniert in dem Umfang, den ich unten ausprobiert habe:
avilella@ubuntu14:~$ python
Python 2.7.6 (default, Oct 26 2016, 20:30:19)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print "foo"
foo
>>> import urllib3
>>>
Ich habe jetzt den Ordner durchgesehen und beides probiert und pip installdabei apt-get install python-${package}Folgendes herausgefunden:
ls /usr/local/lib/python2.7/dist-packages/*/ | grep -v egg | grep '\:' | tr ':' ' ' | grep -v dist-info | xargs -n1 basename | while read i; do sudo pip install $i; done
Auch:
ls /usr/local/lib/python2.7/dist-packages/*/ | grep -v egg | grep '\:' | tr ':' ' ' | grep -v dist-info | xargs -n1 basename | while read i; do sudo apt-get install -y python-${i}; done
Aber immer noch die gleichen Probleme.
Paketanfragen gibt es:

Bei mir läuft eine ähnliche Ubuntu 14.04-VM. Wäre es möglich, bestimmte Ordner per Rsync darauf zu synchronisieren, sodass das nicht mehr funktionierende Ubuntu 14.04 wieder im Normalbetrieb läuft?
Ich scheine an diesem Punkt festzustecken und weiß nicht, wie ich weitermachen soll.
Antwort1
Der developModus von setup.py verknüpft Ihren lokalen Codepfad mit PYTHONPATH.
Wenn Sie das lokale Paket durch installieren
python setup.py develop
, wird das System verändert PYTHONPATHund Sie werden in den Wahnsinn getrieben, weil Sie es aus den Umgebungsvariablen löschen möchten.
Ich finde einen richtigen Weg, sie zu deinstallieren und Ihre Standardeinstellungen PYTHONPATHwiederherzustellenHier. Sie müssen die Option --uninstalloder verwenden -u, um zu entwickeln, also:
python setup.py develop --uninstall
PS: Wenn Sie das Paket nicht beim ersten Mal deinstallieren können, versuchen Sie es bitte erneut, es zu installieren und die Deinstallation noch einmal durchzuführen.
Antwort2
Ich habe festgestellt, dass die einzige Lösung darin besteht, das Betriebssystem von Grund auf neu zu installieren.
