Django 1.8.2和dumpdata出現simplejson錯誤

Question

命令：

% ./manage.py dumpdata

輸出：

CommandError: Unable to serialize database: cannot import name simplejson

zc.buildout配置為在app目錄中安裝simplejson。 我的自定義Python目錄/ usr / local / python中也存在simplejson。

謝謝你的幫助！

堆棧跟蹤：

% ./manage.py dumpdata --traceback

django.utils.simplejson ，不要與混淆simplejson模塊被棄用在Django 1.7，我們現在依靠內置蟒JSON。 如果您正在運行舊版第三方代碼，或某些難以更改的代碼，請執行此操作

try:
    import django.utils.simplejson
except:
    import json as simplejson

如果要編寫新代碼，請編寫此代碼以實現向后兼容：

try:
    import json
except:
    import django.utils.simplejson as json

在您的情況下，是manage.py引發錯誤，還是該錯誤在代碼中的其他地方？ 您可以發布stacktrace嗎？
