![]() Pip install -no-index -find-links="./tranferred_packages" -r requirements.txt Take your offline folder to offline computer and then python -m virtualenv myenv2 download the packages with following code and put all of them to tranferred_packages folder. Now you can go to your offline folder where your requirements.txt and tranferred_packages folder are in there. Open a new terminal and create another env like myenv2. On online machine select a directory with terminal cd and run this code: python -m virtualenv myenvĪfter installing all the packages, you have to generate a requirements.txt so while your virtualenv is active, write pip freeze > requirements.txt Or offline with whl: go to this link, download last version (.whl or tar.gz) and install that with this command: pip install virtualenv-15.1.0-py2.p圓-none-any.whl -userīy using -user you don't need to use sudo pip…. Online with pip: pip install virtualenv -user for doing this I use virtualenv (isolated Python environment) say if you depend on PIL, then libpng, libjpeg, etc must be preinstalled). NOTE: the destination machine needs to have the same version of Python installed, and also any C-based dependencies your app may have must be preinstalled there too (e.g. Just before tarballing though, you must make the virtual environment directory relocatable (see -relocatable option). If the machine that you've built your app has same architecture as the machine on which you want to deploy it, you can simply tarball the entire virtual environment directory into which you easy_install-ed everything. Never install anything into global Python environment. It is (virtualenv that is) pretty much the way to go. within an active virtual environment to avoid contaminating your global Python environment. I highly recommend to invoke setup.py develop. It won't attempt to promiscuously install missing things from Internet. In both cases, the build will fail if one or more dependencies aren't present in /pypi directory. $ easy_install -always-unzip -allow-hosts=None -find-links=/pypi. If you want to install your app and its dependencies into the current python environment, you'll do something like this: You can hack on things, and then rerun the app without rebuilding anything. This way your app will be executed straight from your source directory. $ python setup.py develop -always-unzip -allow-hosts=None -find-links=/pypi If you want to be able to run your app with all the necessary dependencies while still hacking on it, you'll do something like this: ~/src/myapp/setup.py will have install_requires list that mentions one or more things that you have in your /pypi directory. Suppose you have a properly formed Python application in ~/src/myapp. Some packages aren't on PYPI, so same applies to them. I do it a lot when I want a more recent (less stable) version of something. ![]() Some packages may have to be archived into similar looking tarballs by hand. If the package is on PYPI, download it and its dependencies to some local directory. Then upload to your target machine:ġ) Execute tar -zxf to extract the filesĢ) Execute pip install -r wheelhouse/requirements.txt -no-index -find-links wheelhouse to install the libs and their dependencies Then you can go in to requirements.txt and remove un-needed ones.Ģ) Execute command mkdir wheelhouse & pip download -r requirements.txt -d wheelhouse to download libs and their dependencies to directory wheelhouseģ) Copy requirements.txt into wheelhouse directoryĤ) Archive wheelhouse into with tar -zcf wheelhouse This will list all libraries in your environment. One option for creating the requirements file is to use pip freeze > requirements.txt. If you want install python libs and their dependencies offline, finish following these steps on a machine with the same os, network connected, and python installed:ġ) Create a requirements.txt file with similar content (Note - these are the libraries you wish to download): Flask=0.12 ![]()
