【问题描述】：
我想创建一个空白/空 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 身份安装了这些软件包（例如 bedtools、bwa 等），也安装到了其他 conda 环境中，但想要制作一个干净的软件包（为了可重复性）。 p>
这是预期的行为吗？我该如何调试？
我正在（试图）关注这个答案：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
...
关于环境的一些信息如下：

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...
【问题讨论】：
-
你可以尝试运行
conda create -n test-env python而不是conda env create...吗？ -
成功了！ .. 正如你所指出的，我刚刚意识到我没有遵循该链接的答案。
