What is the method to install the ubuntu online server python package to the offline server?

1. Online server export requirement.txt

pip freeze > requirement.txt

After the file is generated, you need to make some modifications to remove unnecessary libraries, otherwise an error will occur during downloading.

2. Download the whl file -> packages

pip download -r requirement.txt -d packages

pip download -r requirement.txt -d packages -i https://pypi.tuna.tsinghua.edu.cn/simple/

After the download is completed, the packages folder contains all the whl files.

3. Offline server ubuntu20.04 Check whether it contains python pip

This version of the server has python3.8.5 installed, but pip is not installed, causing the installation of the whl file to fail.

If you don’t have python, you need to install it yourself.

4. Offline installation of pip

If you install pip, you need to install setuptools in advance, so you need to download two packages.

------Download

setuptools

pip

You need to pay attention to the corresponding python version

I downloaded setuptools ==45.2.0 pip==23.1 They all require python>=3.7. At first I downloaded setuptools==67.6.1, but something went wrong, and finally I chose version 45.

-----Unzip and install setuptools

tar -xvzf setuptools-45.2.0.tar.gz
cd setuptools-45.2.0
python3 setup.py install

There is a problem No module named 'distutils.core'

Baidu Yi I found that the plug-in is missing. If you are offline, you need to download and install it again.

python3-distutils address: https://pkgs.org/search/?q=python3-distutils Sometimes it requires human-machine inspection, and the search is completed Finally, select the server version and python version, which roughly correspond to each other

View the required dependencies

You also need python3-lib2to3, because python already exists, just click in and select the corresponding version.

The plug-in download address is in the download section

Open directly http://archive.ubuntu.com/ubuntu/pool/main/p/python3- stdlib-extensions/python3-distutils_3.8.2-1ubuntu1_all.deb This link starts downloading python3-distutils_3.8.2

Similarly open http://archive.ubuntu.com/ubuntu/pool/main/p/python3 -stdlib-extensions/python3-lib2to3_3.8.2-1ubuntu1_all.deb Download python3-lib2to3_3.8.2

Upload to the same directory after downloading

----Install setuptools dependencies

sudo dpkg -i *.deb

After the installation is complete, install setuptools. After the installation is complete, import to see if there are any problems.

-----Extract and install pip

After the setuptools installation is successful, you can install pip

tar -xvzf pip-23.1.tar.gz
cd pip-23.1
python3 setup.py install

After the installation is completed, execute pip list to check whether it is successful

------Install all whl files

When the offline server pip is ready, it can be installed

pip install --no-index --find-links=packages -r requirement.txt

After the execution is completed, check the pip list. If there is no problem, the transfer is successful. .
