如何导出virtualenv？ [英] How to export virtualenv?

问题描述

我是virtualenv的新手，但是我正在编写django应用程序，最后我将不得不以某种方式进行部署。

I'm new to virtualenv but I'm writting django app and finally I will have to deploy it somehow.

因此，假设我的应用程序正在开发中我在其中安装所有必需库的本地virtualenv。我现在想做的是运行某种脚本，该脚本将带走我的virtualenv，检查其中安装了什么，并生成一个脚本，将所有这些库安装在另一台计算机上的最新virtualenv上。如何做到这一点？请帮忙。

So lets assume I have my app working on my local virtualenv where I installed all the required libraries. What I want to do now, is to run some kind of script, that will take my virtualenv, check what's installed inside and produce a script that will install all these libraries on fresh virtualenv on other machine. How this can be done? Please help.

推荐答案

您不复制粘贴您的virtualenv。您导出所有已安装软件包的列表，例如-

You don't copy paste your virtualenv. You export the list of all the packages installed like -

pip freeze > requirements.txt

然后推送 requirements.txt 将文件存储到您想要部署代码的任何位置，然后只需在开发机上做您的工作-

Then push the requirements.txt file to anywhere you want to deploy the code, and then just do what you did on dev machine -

$ virtualenv <env_name>
$ source <env_name>/bin/activate
(<env_name>)$ pip install -r path/to/requirements.txt

在那里，您已经安装了具有正确版本的所有软件包。

And there you have all your packages installed with the exact version.

您还可以查看 Fabric 使用以下功能自动执行此任务-

You can also look into Fabric to automate this task, with a function like this -

def pip_install():
    with cd(env.path):
        with prefix('source venv/bin/activate'):
            run('pip install -r requirements.txt')
