conda和pip环境管理

1、anaconda换源

制定清华的源：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

有资源显示源地址：

conda config --set show_channel_urls yes

 

2、创建一个名为python36的环境，指定Python版本是3.6

conda create --name python36 python=3.6

3、激活某个环境

activate python36 # for Windows

source activate python36 # for Linux & Mac

deactivate python36 # for Windows

source deactivate python36 # for Linux & Mac

4、 删除一个已有的环境

conda remove --name python36 --all

5、conda包管理

5.1安装xxxx

conda install xxxx 

5.2查看当前环境下已安装的包

conda list 

5.3查看某个指定环境的已安装包

conda list -n python36 

5.4查找package信息

conda search numpy

5.5安装package

conda install -n python34 numpy # 如果不用-n指定环境名称，则被安装在当前活跃环境 也可以通过-c指定通过某个channel安装

6、Conda 更新 

6.1 更新package

conda update -n python34 numpy

 6.2 删除package

conda remove -n python34 numpy

 6.3 更新conda，保持conda最新

conda update -n base conda

 6.4 更新anaconda

conda update anaconda

 6.5 更新python

conda update python 

7、pip使用

 # pip安装包

$ pip install SomePackage

[...]

  Successfully installed SomePackage

# pip查看已安装的包

$ pip show --files SomePackage

  Name: SomePackage

  Version: 1.0

  Location: /my/env/lib/pythonx.x/site-packages

  Files:

   ../somepackage/__init__.py

   [...]

# pip检查哪些包需要更新

$ pip list --outdated

  SomePackage (Current: 1.0 Latest: 2.0)

# pip升级包

$ pip install --upgrade SomePackage

  [...]

  Found existing installation: SomePackage 1.0

  Uninstalling SomePackage:

    Successfully uninstalled SomePackage

  Running setup.py install for SomePackage

  Successfully installed SomePackage

# pip卸载

$ pip uninstall SomePackage

  Uninstalling SomePackage:

    /my/env/lib/pythonx.x/site-packages/somepackage

  Proceed (y/n)? y

  Successfully uninstalled SomePackage
