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. .
