Offline Python Package Install Notes Two common cases which make the install of Python packages harder due to networking issues are: a) Install behind a Proxy b) Install without access to the internet

(a) Install behind a Proxy In the case where the target machine connects to the internet over a network proxy, export the following environment vars, as appropriate - http_proxy and https_proxy. Eg:

$ export https_proxy=http://proxy.mydomain.com: $ export http_proxy=http://proxy.mydomain.com: $ pip install (b) Install without access to the internet In the case where the target machine does not have connectivity to the internet, you have to download the package and dependencies using a machine which does have connectivity to the internet. After which the install can follow. Sample instructions -

Step 1. Download Packages for Offline Install Execute the instructions below download the packages on a machine which is able to connect to the internet.

if a single package is being installed

$ pip install --download /tmp/offline_packages

or, if a list of dependencies are to be installed

$ pip install --download /tmp/offline_packages -r requirements.txt Step 2. Transfer downloaded packages Transfer downloaded packages to the target machine where the install is to be performed. Use scp/sftp/etc.

Step 3. Install packages Assuming the directory /tmp/transferred_packages contains the contents of /tmp/offline_packages from the earlier machine, execute the following steps on the the target machine.

if a single package is being installed

$ pip install --no-index --find-links="/tmp/tranferred_packages"

if a list of dependencies are to be installed

$ pip install --no-index --find-links="/tmp/tranferred_packages" -r requirements.txt
