问题描述
我有2个Python版本
I have 2 Python versions
- Python 3.4.3
- Python 2.7.10
Env变量可与Python 3.4(在我的系统中)一起使用，因此当我pip install *package_name时，它将仅将软件包安装到Python 3.4中
Env variable works with Python 3.4(in my system), so when I pip install*package_name it will only install the package into Python 3.4
我还有一个适用于Python 2.7的系统变量-%python27%-也.
I have a system variable for Python 2.7 -- %python27% -- also.
我的问题是；我如何在不更改Env的情况下将包/模块安装到Python 2.7中.多变的.
My question is; how can I pip install a package/module into Python 2.7 without changing the Env. Variable.
注意:％python27％pip install *package_name不起作用.
Note: %python27% pip install *package_name doesn't work.
谢谢.
推荐答案
您应该具有pip的多个可执行文件.
You should have multiple executables of pip.
交替使用pip2和pip3.
Use pip2 and pip3 interchangeably.
无论如何，您应该考虑使用virtualenv软件包，将其初始化为virtualenv -p /usr/bin/python2.7 env_name或virtualenv-3.4 -p /usr/bin/python3.4 env_name之类，然后每次使用代码时，键入source env_name/bin/activate，并且"python"应别名为虚拟化版本.
Anyway, you should consider using virtualenv package, initialize it like virtualenv -p /usr/bin/python2.7 env_name or virtualenv-3.4 -p /usr/bin/python3.4 env_name then each time you use your code, type source env_name/bin/activate and "python" should be aliased to virtualised version.
