使用virtualenv,我使用默认版本的Python(2.7)运行我的项目.在一个项目中,我需要使用Python 3.4.
我brew install python3以前在Mac上安装它.现在,我如何创建一个使用新版本的virtualenv？
例如sudo virtualenv envPython3
如果我尝试:
virtualenv -p python3 test
我明白了:
Running virtualenv with interpreter /usr/local/bin/python3
Using base prefix '/usr/local/Cellar/python3/3.4.0_1/Frameworks/Python.framework/Versions/3.4'
New python executable in test/bin/python3.4

ERROR: It …由于某些原因我无法解释或google,即使用最简单的例子,py2app也会崩溃.我使用python 3.4.1虚拟环境创建,Projects/Test/virtenv其中py2app通过pip安装.
这是输出$pip list:
altgraph (0.12)
macholib (1.7)
modulegraph (0.12)
pip (1.5.6)
py2app (0.9)
setuptools (3.6)
foo.py是一个保存在Projects/Test /中的hello world示例文件,包含一行:
print('hello world')
setup.py保存在Projects/Test中,生成者$py2applet --make-setup foo.py:
"""
This is a setup.py script generated by py2applet
Usage:
python setup.py py2app
"""
from setuptools import setup
APP = ['foo.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
这是运行的完整输出$python setup.py py2app(所有pip和python命令都是在激活虚拟环境的情况下完成的):
