python - 创建干净的 conda 环境

Question

我想创建一个空白/空的 conda 环境，但新创建的环境似乎正在从 root 或其他环境中获取包。我已经在系统上以 root 身份安装了这些包(例如 bedtools、bwa 等)，也安装到其他 conda 环境中，但我想制作一个干净的(为了重现性)。

这是预期的行为吗？我该如何调试？

我(试图)遵循这个答案:https://stackoverflow.com/a/37216638/3294994

$ conda env create -n test-env python
$ source activate 
$ conda env export
name: test-env
channels:
- conda-forge
- biconda
- anaconda
- defaults
dependencies
...
python=3.6.2=0
bcftools=1.6=0
bedtools=2.26.0=0
bwa=0.7.15=1
...
picard=2.14=py36_0
...

有关以下环境的一些信息:

顺便说一句，我遇到的原始问题如下:

$ source activate test-env
$ conda install jupyter
Fetching package metadata ...........
Solving package specifications: .

UnsatisfiableError: The following specifications were found to be in conflict:
  - imagemagick
  - jupyter
  - python 3.6*
Use "conda info <package>" to see the dependencies for each package.

我猜这是因为新创建的环境 test-env 中已经有包了...

Answer 1

您可以通过键入 conda create -n vEnv python 来创建一个新环境

这将创造一个全新的环境。顺便说一句，这与您进入 GUI 并点击创建按钮是一样的。这样你创建的 env 将被放置在随处可用的 anaconda 文件中的 envs 下，所以你可以通过执行以下操作简单地激活它:conda activate vEnv

您可以像这样检查 pip 和 conda 包(一旦您激活了您的环境):点列表conda 列表
