运行多个Python版本
我想在我的机器上运行多个 Python 版本。有没有 Python 版本管理器，我可以在多个 Python 版本之间切换，而无需调用 Python 二进制文件的完整路径？我尝试过 virtualenv，它似乎只涵盖运行多个 Python 库版本的问题。
感谢您的帮助。
I want to run multiple Python versions in my box. Is there any version manager for Python where I can switch between multiple Python versions without having to call the full path of the Python binary? I have tried virtualenv and it seems to only cover problems running multiple Python library versions.
Thanks for your help.

从 bash 调用 python 时，您可以尝试使用别名。
假设您有一个名为 script.py 的脚本，其中包含以下内容：
因此，使用不同版本的 python 启动脚本如下所示：
When calling python from bash you could try an alias.
Let's say you have a script called script.py with following content:
So, launching a script with a different version of python looks like:
我使用 virtualenv 来跟踪项目所需的不同环境。我可以在一个环境中设置 django 1.0，或者在另一个环境中设置 django 1.2。您也可以使用它来设置您想在特定环境中使用哪个版本的 python。以下是该网站的链接，该网站提供了有关如何运行的出色示例和教程： http://pypi.python .org/pypi/virtualenv
I use virtualenv to keep track of different environments I need for my projects. I may setup django 1.0 in one environment or django 1.2 for another. You can use it to set which version of python you'd like to use in a particular environment as well. Here's the link to the site which has great samples and tutorials for how to get running: http://pypi.python.org/pypi/virtualenv
您不必使用完整路径。
这能回答你的问题吗？
You don't have to use the full path.
Does that answer your question?
安装多个解释器版本
node-build是安装多个 Node 版本的常用工具。node-build安装：node-build用法：python-build是安装多个Python版本的常用工具。python-build安装：python-build用法：管理多个解释器版本
rvm、rbenv和chruby是管理多个 Ruby 版本的常用工具。他们启发了nvm、nodenv和chnode，它们是管理多个 Node 版本的等效工具。他们还启发了pyenv和chpython，它们是用于管理多个 Python 版本的等效工具（没有与rvm等效的工具）据我所知）。调用 Ruby 命令时（
ruby、irb、）自动切换位于已安装 Ruby 版本的、bin目录中的目标可执行文件rakegem、…）根据当前或最近父目录的 .ruby-version 文件中定义的 Ruby 版本，这些工具使用不同的策略（从最重到最轻） ):rvm通过重新定义cd命令，在每次调用cd命令之前更新PATH环境变量；rbenv通过执行代理可执行文件 (垫片）；chruby在每次调用命令之前更新PATH环境变量，方法是执行使用preexec_functions（对于 Zsh）和PROMPT_COMMAND 挂钩到 shell 的函数用于 Bash。rvm策略的缺点是它是侵入性的且缓慢。rbenv策略的缺点是它很复杂，并且需要在每次安装 Ruby 版本或 Ruby 包（gem< /em>) 提供可执行文件。chruby策略不存在这些问题，因此chruby是推荐的工具。chnode安装：chnode用法：chpython安装：chpython用法：Installing Multiple Interpreter Versions

rvm,rbenv, andchrubyare common tools for managing multiple Ruby versions. They inspirednvm,nodenv, andchnodewhich are equivalent tools for managing multiple Node versions. They also inspiredpyenvandchpythonwhich are equivalent tools for managing multiple Python versions (there is norvmequivalent as far as I know).To automatically switch the targeted executables located in the
bindirectories of the installed Ruby versions when invoking a Ruby command (ruby,irb,rake,gem, …) based on the Ruby version defined in the .ruby-version file of the current or nearest parent directory, the tools use different strategies (from the heaviest to the lightest):rvmupdates thePATHenvironment variable before each invocation of thecdcommand by redefining thecdcommand;rbenvinvokes the Ruby command in a dedicated environment with an updatedPATHenvironment variable by executing a proxy executable (shim);chrubyupdates thePATHenvironment variable before each invocation of a command by executing a function hooked into the shell withpreexec_functionsfor Zsh andPROMPT_COMMANDfor Bash.The drawback of the
rvmstrategy is that it is invasive and slow. The drawback of therbenvstrategy is that it is complex and requires shims to be regenerated (rehashed) at each installation of a Ruby version or Ruby package (gem) that provides an executable. Thechrubystrategy does not have those issues sochrubyis the recommended tool.chnodeinstallation:chnodeusage:chpythoninstallation:chpythonusage:
