update anaconda

Upgrade all kits

conda upgrade --all

update spyder

There are many posts giving suggestions similar to conda update anaconda; pip install --upgrade spyder. The following is the method I successfully implemented according to the official suggestion:

conda install spyder=4.0.0b7
#执行完后打开spyder，提示rtree版本不符
conda install rtree
#成功！

There are many possibilities for error reporting. For example, if the Solving environment is unsuccessful, uninstall the original version and then use the command successfully; another example is that the Spyder version to be tested does not have the correct spyder-kernels version installed. Spyder 3 corresponds to spyder-kernels 0.x, and Spyder 4 corresponds to spyder-kernels 1.x, which means that additional execution is required:

conda install -c spyder-ide spyder-kernels=1.*
#conda install -c <channel> <software>
#有些包在conda默认的channels中不包含，-c这个参数可以指定软件下载的镜像位置

update python

I am updating from 3.6 to 3.7
1. Go to the Python official website to download the installation package for the corresponding system (a bit troublesome)
2. Install the Python environment through the Anaconda suite (but there will be two anacondas after installation, to avoid conflicts, you need to uninstall the original one)
URL
download Then run it directly, except for a few items that need to be modified (listed below), click next for the rest. Note

: Do not directly conda update python! It may cause the version to be older, it will not work! Of course, if you need to specify the version of python, you can do this:

conda create -n py34 python=3.4 anaconda
conda activate py34 #激活这个新的配置环境
python --version #检查版本
#打开anaconda navigator，会现多出来一个可选择的环境

Install and update packages

conda install package_name
conda update package_name

pip3 install package_name
pip3 install --upgrade package_name
