Django通知我“ ImportError:没有名为pytz的模块”,但是当我使用pip进行安装时,得到以下结果:
Requirement already satisfied (use --upgrade to upgrade): pytz in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
它是否可能在错误的位置查找,或者我需要尝试将其安装在其他位置?
这是完整的堆栈跟踪:
Internal Server Error: /basicloginwebservice/

谢谢
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras
是与Apple提供的Python 2.7(/usr/bin/python2.7
)关联的位置。从回溯中无法得知,但很有可能Django是在不同的Python 2.7实例下运行的,也许与from链接/usr/local/bin
。当有多个Python实例并且您pip
直接从命令行使用时,会出现这类问题。确保pip
为使用的每个Python安装了一个版本。并且,为确保您使用的正确实例pip
,可以通过以下方式调用它:
python -m pip install pytz
替换用于python
运行Django的相同路径。
另一种方法是始终使用激活的方法virtualenv
,该方法应确保首先在流程中找到权限python
和pip
实例PATH
。
