python - virtualenv 中引发错误 - dyld : Library not loaded:/Library/Frameworks/Python. Framework/Versions/3.4/Python

Question

我的 virtualenv 中有以下场景。

激活我的 virtualenv env-trails_dj 后

source env-trails_dj/bin/activate

并尝试启动 python，我收到以下错误:

(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 路径如下所示:

(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，但它是空的...

(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 ..

也许只是缺少引用，但我无法识别

注意:不确定是什么原因造成的。可能是升级到 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

-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 正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

Answer 1

您的 Python 框架似乎安装不正确或已删除。 您的虚拟环境在/Library/Frameworks/Python.framework/Versions/3.4/Python 中查找符号链接(symbolic link)的 python 文件。您可以通过输入 ls -la /Users/udos/PycharmProjects/trails_dj/env-trails_dj/bin 来确认这一点。 — 应该有一个指向您的 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。
