问题描述
我的virtualenv中有以下情形。
在激活我的virtualenv env-trails_dj之后
source env-trails_dj/bin/activate
并尝试启动python，出现以下错误：
(env-trails_dj) AirTime:trails_dj udos$ python
dyld: Library not loaded: /Library/Frameworks/Python.framework/Versions/3.4/Python
Referenced from: /Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin/python
Reason: image not found
Trace/BPT trap: 5
virtualenv PATH如下所示：
(env-trails_dj) AirTime:trails_dj udos$ echo $PATH
/Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin:/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
我检查了以下目录，但它为空...
(env-trails_dj) AirTime:trails_dj udos$ ls -al /Library/Frameworks/Python.framework/Versions/
total 0
drwxrwxr-x 2 root wheel 68 Jul 13 10:58 .
drwxr-xr-x 6 root wheel 204 Jul 13 10:43 ..
可能只是缺少的参考，但我无法识别
注意：不确定是什么原因造成的。 也许升级到OS X El Capitan（10.11.1） 。
更新：
(env-trails_dj) AirTime:trails_dj udos$ ls -la /Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin/
total 248

检查启动了哪个python版本：
env-trails_dj) AirTime:trails_dj udos$ which python
/Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin/python
根据错误，python在另一个目录中查找：
(env-trails_dj) AirTime:trails_dj udos$ python
dyld: Library not loaded: /Library/Frameworks/Python.framework/Versions/3.4/Python
Referenced from: /Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin/python
Reason: image not found
Trace/BPT trap: 5
update_2：
(env-trails_dj) AirTime:trails_dj udos$ pip install Python
dyld: Library not loaded: /Library/Frameworks/Python.framework/Versions/3.4/Python
Referenced from: /Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin/python
Reason: image not found

看来您的Python框架安装不正确或已删除。
您的虚拟环境在/Library/Frameworks/Python.framework/Versions/3.4/Python中寻找符号链接的python文件。
您可以通过输入ls -la /Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin来确保这一点-应该有指向您的Python安装的链接。
尝试从头开始重新安装Python，然后使用： /Library/Frameworks/Python.framework/Versions/3.4/python -m venv ~/PycharmProjects/<newVirtualEnv>创建新环境或尝试现有环境。
