python：使用conda安装破折号

Question

How can I install dash step-by-step? I'm really new at importing packages in python. I have python 3.6.4 on my computer and I'm trying to install the dash package, dash_core_components .

I tried to type in the anaconda prompt: conda install dash (not available for current channels) I also tried to install pip through conda: conda install pip then pip install dash ... but got an error also.

I'm really new and honestly don't really know what I'm doing. I got a pop-up from spyder when I open it saying to never use pip, it can break stuff. I don't understand why.

Answer 1

Here are the commands to get conda to install dash:

conda install -c conda-forge dash-renderer
conda install -c conda-forge dash 
conda install -c conda-forge dash-html-components 
conda install -c conda-forge dash-core-components
conda install -c conda-forge plotly

If you go to the Anaconda site and search for the package they will give you the conda command to install the package.

Answer 2

Along with the others. You can also try the following:

import pip

pip.main(['install', 'dash-renderer', '--user'])
pip.main(['install', 'dash', '--user'])
pip.main(['install', 'dash-html-components', '--user'])
pip.main(['install', 'dash-core-components', '--user'])
pip.main(['install', 'plotly', '--user'])

Note: This will install the packages only for the current session.

or

Try the following too:

!pip install dash-renderer
!pip install dash
!pip install dash-html-components
!pip install dash-core-components
!pip install plotly

Answer 3

Per most recent update from Dash website, the below should now be sufficient:

 pip install dash==1.8.0

Note: starting with dash 0.37.0, dash automatically installs dash-renderer, dash-core-components, dash-html-components, and dash-table, using known-compatible versions of each. You need not and should not install these separately any longer, only dash itself.

Per Lucas's comment above, with Anaconda distribution use :

conda install -c conda-forge dash

Answer 4

Try one of the following:

conda install -c conda-forge dash
conda install -c conda-forge/label/broken dash

It worked for me for a different package (opencv). Source at this link from anaconda.org
