如何离线安装ipywidgets（从文件）

Question

So I am trying to install ipywidgets-0.0.1 into my Anaconda environment. I am running Anaconda3. Unfortunately, the machine I need to install it on does not have internet access.

The basic way to install the package is to run conda install ipywidgets , but of course this gives the following error:

Fetching package metadata: Could not connect to https://repo.continuum.io/pkgs/p

Package plan for installation in environment C:\Program Files\Anaconda3:

This makes sense, since the box can't access the internet. I downloaded the ipywidgets tarball from the listed URL at https://repo.continuum.io/pkgs/free/win-64/ipywidgets-0.0.1-np19py34_0.tar.bz2 , and I ssh'ed it onto the box.

What command can I run on the box (it is a Windows 7 environment) so that it will run the install as local, looking at the downloaded tarball to unpack rather than trying to access the internet to get the file?

Answer 1

Download the whole package and its dependencies to some local directory You can get it from PYPI ipywidgets

Let's consider you donwloaded from PYPI and you have ~/src/ipywidgets with ~/src/ipywidgets/setup.py which will have install_requires with a list of dep. in your /pypi directory. Like so:

install_requires=['hello', 'etc', ...]

To install your app and its dep. into the current python env., you've to do something like:

$ cd ~/src/ipywidgets
$ easy_install --always-unzip --allow-hosts=None --find-links=/pypi

Note that the build will fail if one or more dependencies are missing

Answer 2

If you want to use conda for this, might as well if you are already using anaconda, you should also be able to do:

conda install --offline PATH_TO_FILE/ipywidgets-0.0.1-np19py34_0.tar.bz2

Where, of course, PATH_TO_FILE is just the path to the file you've downloaded.
