Anaconda(Python科学计算环境)教程

简明版本

输入 conda list 来看所有安装时自带的Python扩展。

安装扩展conda install xxx . 如果需要指定版本，也可以直接用[package-name]=x.x

用conda创建一个名叫python2的版本为python2.7的环境。
conda create -n python2 python=2.7
这样就会在Anaconda安装目录下的envs目录下创建python2这个目录。

Creating an environment with commands
（https://conda.io/docs/user-guide/tasks/manage-environments.html#creating-an-environment-with-commands）

• To create an environment:

conda create --name myenv

This creates the myenv environment in/envs/. This environment uses the same version of Python that you are currently using, because you did not specify a version.

• To create an environment with a specific version of Python:

conda create -n myenv python=3.4

• To create an environment with a specific package:

conda create -n myenv scipy

• To create an environment with a specific version of a package:

conda create -n myenv scipy=0.15.0

• To create an environment with a specific version of Python and multiple packages:

conda create -n myenv python=3.4 scipy=0.15.0 astroid babel

TIP: Install all the programs that you want in this environment at the same time. Installing 1 program at a time can lead to dependency conflicts.

• To automatically install pip or another program every time a new environment is created, add the default programs to the create_default_packages section of your .condarc configuration file. The default packages are installed every time you create a new environment. If you do not want the default packages installed in a particular environment, use the –no-default-packages flag:

conda create --no-default-packages -n myenv python

TIP: You can add much more to the conda create command. For details, run conda create –help.

• List all environments

conda info --envs

or

conda env list
