How to install packages offline?

Question

What\'s the best way to download a python package and it\'s dependencies from pypi for offline installation on another machine? Is there any easy way to do this with pip or

Answer 1

I had a similar problem. And i had to make it install the same way, we do from pypi.

I did the following things:

1. Make a directory to store all the packages in the machine that have internet access.

   mkdir -p /path/to/packages/
   

2. Download all the packages to the path

Edit: You can also try:

python3 -m pip wheel --no-cache-dir -r requirements.txt -w /path/to/packages

pip download -r requirements.txt -d /path/to/packages

Eg:- ls /root/wheelhouse/  # **/root/wheelhouse** is my **/path/to/packages/**

3. Tar the packages directory and copy it to the Machine that doesn't have internet access. Then do,

   cd /path/to/packages/
   tar -cvzf packages.tar.gz .  # not the . (dot) at the end
   

Copy the packages.tar.gz into the destination machine that doesn't have internet access.

4. In the machine that doesn't have internet access, do the following (Assuming you copied the tarred packages to /path/to/package/ in the current machine)

   cd /path/to/packages/
   tar -xvzf packages.tar.gz
   mkdir -p $HOME/.config/pip/
   vi $HOME/.config/pip/pip.conf
   

and paste the following content inside and save it.

[global]
timeout = 10
find-links = file:///path/to/package/
no-cache-dir = true
no-index = true

5. Finally, i suggest you use, some form of virtualenv for installing the packages.

   virtualenv -p python2 venv # use python3, if you are on python3
   source ./venv/bin/activate
   pip install 
   

You should be able to download all the modules that are in the directory /path/to/package/.

Note: I only did this, because i couldn't add options or change the way we install the modules. Otherwise i'd have done

pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt
