virtualenv中引发的错误-dyld：未加载库：/Library/Frameworks/Python.framework/Versions/3.4/Python

Question

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
drwxr-xr-x  16 udos  staff    544 Sep 22 22:13 .

-rwxr-xr-x   1 udos  staff  25920 Sep 11 20:25 python3.4

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
Trace/BPT trap: 5

Answer 1

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。
