问题描述

我的 conda 管理下有多个环境，如下所示

I have multiple environments under my conda management, as shown below

ss-MacBook-Pro$ conda env list
# conda environments:
#
base                  *  /miniconda2
testenv                  /miniconda2/envs/testenv
testenvpy3               /miniconda2/envs/testenvpy3

我可以安装一个可以在多个环境中生效的软件包吗?通过阅读 文档，我的印象是不可能，因为如果我这样做了

Can I install a package that becomes effective across multiple environments? By reading the documentation, I got the impression that it is NOT possible, because if I do

conda install package-name

它只会安装到 base 环境(当前活动环境)中，但不适用于其他环境.我记得我以前可以通过某种方式实现在virtualenv下安装一个对多个环境有效的包.

it will only get installed into the base environment (the current active environment), but it does not apply to other environments. I remember I can somehow achieve install a package effective to multiple environments under virtualenv before.

有人可以分享这个建议吗?

Can someone share the suggestion?

推荐答案

conda install 只为当前(激活的)环境安装包.文件将安装在特定环境的目录中.如果您想在所有环境中使用特定包，则必须为每个环境(base、testenv、testenvpy3).

conda install only installs packages for the current (activated) environment. Files will be installed in the directory for the specific environment. If you want a specific package in all environments, you'll have to conda install that package for each of your environments (base, testenv, testenvpy3).

要在环境之间切换，您只需激活您切换到的环境.语法取决于 Anaconda 版本或您的操作系统.对于较新的 Anaconda 版本，conda activate 有效，对于旧版本，source activate 适用于 Unix 系统和 activate <环境名称> 适用于 Windows.

To switch between environments you just need to activate the one you switch to. The syntax depends Anaconda version or your OS. For newer Anaconda versions, conda activate <env name> works, and for older versions, source activate <env name> for Unix systems and activate <env name> for Windows.
