pip install does not install all dependencies #29
Description
Heads up! Edited on October 24, 2018
This issue comes up on google searches when folks haven't installed the necessary packages to run Dash.
If you find yourself here, then please visit the official installation instructions here: https://dash.plot.ly/installation
Thank you 🙇
In particular, I had to pip install each of dash_core_components, dash_html_components and dash_renderer to make examples work.

FWIW, this is on OSX, Python 3.6 installed from Anaconda

Dash_core_components and dash_html_components are not meant to be be dependencies of dash. The rationale behind this is to allow users to make and customize their own React components and customize the look and feel of their apps without being forced to a specific UI set.
See here: https://plot.ly/dash/plugins

Oh yeah - that makes sense. Still applies to
dash_renderer, though?chriddyp commentedon Jun 22, 2017
It doesn't. I've separated them as I didn't want to bump a new version of
dashevery timedash_rendererupdates.I could probably set the current install to use a range of
dash_rendererversions, like:install_requires=dash_renderer>=0.7.1 & dash_renderer<0.8.0. If something breaks compatability between the API of the two packages, they'll get bumped together.arokem commentedon Jun 22, 2017
Okidoke. Sorry for the noise -- feel free to close this.
chriddyp commentedon Jun 22, 2017
No worries! Thanks for bringing it up. I think that I'll keep them separate from now for a couple of more releases just so that I don't introduce a dependency that I'll regret later.
For now, I'll refer future google searchers to the installation section in the docs: https://plot.ly/dash/installation

I think that
dash_rendererstill has to be a requirement for pip because of this line?traincroft commentedon Mar 5, 2018
I understand the rationale - but - how does a newbie install a workable version of dash (Windows 7)?
waynenilsen commentedon Mar 5, 2018
just
pip install dash_rendererit is a requirement to run this code as I pointed out abovechriddyp commentedon Mar 6, 2018

Hi , I have gone to https://dash.plot.ly/ and followed user guide to install & to run 1st example.
I am using python version 3.6.5 & PyCharm on windows 10
Initially I got a fault for it not having:
dash_renderer
so I used :
from dash import dash_renderer as dr
now I keep getting :
Traceback (most recent call last):
File "C:/Users/drake/Downloads/_Python/Dash1/app2.py", line 2, in
import dash_core_components as dcc
ModuleNotFoundError: No module named 'dash_core_components'
or for dash_html_components
depending on my order of installing.
I have uninstalled all of the installs:
pip install dash==0.21.1 # The core dash backend
pip install dash-renderer==0.12.1 # The dash front-end
pip install dash-html-components==0.10.1 # HTML components
pip install dash-core-components==0.22.1 # Supercharged components
pip install plotly --upgrade # Plotly graphing library used in examples
and even gone to github for versions of:
dash-html-components==0.10.1 # HTML components
dash-core-components==0.22.1 # Supercharged components
I just cannot get the first tutorial (nor the next couple) to work:
Generating HTML with Dash
Can you please advise where I should go for help on this please.
When I check >>> help ('modules') it shows all the above pip installs there.
But in the app.py file it just won't install:
dash_core_components or
dash_html_components
thank you in anticipation

OK, I think I'm being too pedantic. Let's just include
dash-renderer,dash-core-components, anddash-html-componentsin the package but keep references to these (with their version numbers!) in the installation instructions.chriddyp commentedon Sep 4, 2018
