Pip: Die Testsuite schlägt aufgrund der SVN-Prüfung fehl

Umgebung

• Pip-Version: 720c77aa
• Python-Version: 3.8.1
• Betriebssystem: macOS Catalina 10.15.4

Beschreibung

Diese Woche habe ich auf macOS 10.15.4 aktualisiert. Wenn ich jetzt svn --version ausführe, wird folgender Fehler angezeigt:

pip master $ svn --version                                                                                                                                                
svn: error: Failed to locate 'svn'.
svn: error: The subversion command line tools are no longer provided by Xcode.

Wenn ich die Pip-Testsuite ausführe, werden während der Testerkennung ähnliche Fehler angezeigt, die dazu führen, dass die gesamte Testsuite nicht ausgeführt wird.

Erwartetes Verhalten

Tests für SVN sollten Tests wirklich nicht blockieren.

Wie zu reproduzieren

Vermutlich:

1. Update auf macOS 10.15.4.
2. Führen Sie tox .
