I believe that every python knows how to develop different python projects. sometimes, the python version is different and the software package version is different. The best solution to this problem is to build an independent python environment for different projects. Let's take a look. Preface I believe it is normal for python developers to have different python versions on the machine, because some development projects use 2.6 or 2.7, and some use 3.0 + versions, we need to use our virtual

Recommended for Yyuu/pyenv GitHub, which allows you to install as many Python versions as you like without modifying your system's own python, and that the versions are isolated from one another, and are easy to manage in multiple versions.pyenvCan be used to manage and switch between differentpythonVersions, compared with virtualenv and Anacondo to create a virtual Python environment,pyenvEasier and lighter to use.

Python pyenv and pythonpyenv I. Introduction We usually Install Multiple Python versions in the operating system, so it is troublesome to switch the Python version. pyenv provides a simple method, it is a simple and elegant tool that can easily switch between multiple Python versions. Pyenv has the following functions: 1) switch the global Python version 2) provide the corresponding Python version for a single project 3) use environment variables to allow you to rewrite Python version 4) searc

Because there are differences between Python2 and 3, it may be necessary to switch back and forth between 2 and 3 in your daily work. In the same Python version, there may be projects that need to use django1.8, and other projects need to use django1.9, so if you can switch freely in the local environment, it is very convenient for developers. Remember when I first started learning, because of the Python version of the problem, to their Mac reload many times, now think, really is a runny nose a

answer this question, purposely ran to a CentOS 6.5 installed a Python3 (without the Ubuntu environment), and then installed a PIP, through LN to create a connection, alias create aliases These operations, prove Python2 and Python3 Can still be perfect coexistence. The main problem is not to be able to coexist, but in the default pip Install command to Python3 installation of the procedure itself is wrong, the following is my solution: The environment has been preceded by Python and Pip,
