将Pip包转移到conda [英] Transfer Pip packages to conda

问题描述

我目前正在使用共享的Ubuntu计算机，该计算机具有 python2.7 和通过 pip 安装的多个软件包.

I am currently using a shared Ubuntu machine which has python2.7 and multiple packages installed via pip.

$ python --version
Python 2.7.12

$ pip --version
pip 18.0 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)

$ pip list
Package                            Version
---------------------------------- -----------
asn1crypto                         0.24.0
awscli                             1.11.101
backports-abc                      0.5
...
..
.

我要安装 conda ，并具有 Python 2.7 和 Python 3.6 环境.

I want to install conda and have Python 2.7 and Python 3.6 environment.

如何在conda env( 2.7 和 3.6 )中安装当前已安装的所有软件包( pip list )?我不关心软件包的版本.可以为每个软件包安装相同版本或最新版本.

How can I install all the packages currently installed (pip list) in both conda env (2.7 and 3.6) ? I am not concerned with package version. Fine to install the same version or latest version for each package.

推荐答案

安装相同版本

首先，获取通过pip安装到文件中的软件包列表:

Install same versions

First, get a list of packages installed via pip into a file:

pip freeze > packages.txt

然后在两个环境中使用conda安装它们:

Then install them using conda inside your two environments:

conda install --yes --file packages.txt

安装忽略版本

pip Frozen 将吐出带有版本的软件包.要删除它们，请运行以下命令:

Install ignoring versions

pip freeze will spit out packages with versions. To remove them, run this instead:

pip freeze | sed s/=.*// > packages.txt

这样，您将更有可能使用conda成功安装它们，而不会发生依赖关系冲突.

This way you will more likely succeed in installing them using conda without getting dependency conflicts.

如果您安装了很多软件包，conda可能找不到其中一些.在这种情况下，请查看此问题.

If you have a lot of packages installed, conda might fail to find some of them. In that case, check out this question.
