Offline Install Python Package with pip3

Yes you can do it with pip3 (or pip).

And it is simple.

Now we assume you have two computers, both have python3 and pip3 installed, and:

• hostA has internet connection
• hostB does not have internet connection

Our task is to download python package from hostA and copy downloads to install packages offline on hostB.

1. Put all of your required python packages into a requirement.txt file. See more details at https://pip.readthedocs.io/en/1.1/requirements.html Assume your requirement.txt looks like:

   hostA$ ls
   requirements.txt
   hostA$ cat requirement.txt
   pandas
   pip-autoremove
   scikit-learn

2. Use pip3 to download python packages specified in requirement.txt:

   hostA$ mkdir requirement
   hostA$ ls
   requirements  requirements.txt
   hostA$ pip download -r requirements.txt -d requirements
   Collecting pandas (from -r requirements.txt (line 1))
   ...

3. Copy both:

   • fie requirement.txt and
   • directory requirement from hostA to hostB.

4. On hostB, under directory contains both:

   • fie requirement.txt and
   • directory requirement

   hostB$ ls
   requirements  requirements.txt
   hostB$ pip install --no-index --find-link=requirements -r requirements.txt
   Collecting pandas (from -r requirements.txt (line 1))
   ...
   

Tada!
