我将如何通过 python 脚本运行 lsvirtualenv 或任何其他 virtualenvwrapper 函数? [英] How would I run lsvirtualenv or any of the other virtualenvwrapper functions via python script?
问题描述
我正在尝试运行 virtualenvwrapper.sh
命令(即:lsvirtualenv 和 mkvirtualenv).
我尝试使用
subprocess.call(["lsvirtualenv"])
但它似乎不起作用.它给了我以下错误消息:
回溯(最近一次调用最后一次):文件importMaster.py",第 6 行,在 <module> 中virtualEnvs = subprocess.call(["lsvirtualenv"])文件/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py",第 524 行,调用中返回 Popen(*popenargs, **kwargs).wait()文件/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py",第 711 行,在 __init__ 中错误读取,错误写入)文件/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py",第 1308 行,在 _execute_child引发 child_exceptionOSError: [Errno 2] 没有那个文件或目录
由于这些函数位于 virtualenvwrapper.sh
文件中,我将如何在 python 脚本中引用该函数?
TIA
你需要使用 source $(which virtualenvwrapper.sh) &&
shell=True
中的 shell=True
.
示例:
<预><代码>>>>从 __future__ 导入 print_function>>>从子流程导入 Popen, PIPE>>>p = Popen("source $(which virtualenvwrapper.sh) && lsvirtualenv", shell=True, stdout=PIPE)>>>打印(p.stdout.read())10颗======环境光============请参阅 Popen Constructor 的文档.>
I'm attempting to run virtualenvwrapper.sh
commands (ie: lsvirtualenv and mkvirtualenv).
I attempted to use
subprocess.call(["lsvirtualenv"])
but it does not seem to work. It gives me the following error message:
Traceback (most recent call last):
File "importMaster.py", line 6, in <module>
virtualEnvs = subprocess.call(["lsvirtualenv"])
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 524, in call
return Popen(*popenargs, **kwargs).wait()
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 711, in __init__
errread, errwrite)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1308, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
Since these functions are inside of the virtualenvwrapper.sh
file, how would I go about referencing the function in a python script?
TIA
You need to use source $(which virtualenvwrapper.sh) && <your command>
with shell=True
.
Example:
>>> from __future__ import print_function
>>> from subprocess import Popen, PIPE
>>> p = Popen("source $(which virtualenvwrapper.sh) && lsvirtualenv", shell=True, stdout=PIPE)
>>> print(p.stdout.read())
