pytz在Mac上安装

的Django告诉我的“导入错误：没有模块名为pytz”，但是当我去使用PIP安装它，我得到这样的结果：pytz在Mac上安装

Requirement already satisfied (use --upgrade to upgrade): pytz in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

是否有可能是在寻找错误的位置，或者我需要尝试在别的地方安装它？

以下是完整的堆栈跟踪：

/System/Library/Frameworks/Python.framework/Versions/2.7/Extras与Apple提供的Python 2.7（/usr/bin/python2.7）相关联的位置。从回溯中无法判断，但是Django可能在Python 2.7的另一个实例下运行，可能与/usr/local/bin有关。如果有多个Python实例，并且您直接从命令行使用pip，则可能会出现这些问题。确保您为每个正在使用的Python安装了pip版本。而且，为了确保您使用的pip正确的实例，你可以调用这样说：

python -m pip install pytz

替代python用来运行Django的相同的路径。

另一种方法是始终使用激活virtualenv应确保正确python和pip实例首次发现的过程PATH。
