1. Scene introduction
On some servers, after we set up the Python environment, due to network restrictions on the server, we cannot directly download and install through the pip command Install. Therefore, we need to download the required dependency package files on a server with normal Internet access, then copy them to the target server, and run them on the target server through Python’s dependency package. pip
2. Prepare the requirements.txt file
requirements.txtThe file lists a list of dependent packages, indicating the dependent packages you want to download and the corresponding versions.
This file can be created in two ways, namely using the pip command and manually.
jupyter==1.0.0
notebook==6.1.0
(1) The pip command creates requirements.txt, which can generate a list of the current server's Python dependency packages into the requirements.txt file.
【pip list】
【pip freeze >requirements.txt】
(2) Manually create
requirements.txt, directly create a newrequirements.txtfile, and then fill in the required dependency packages and corresponding version numbers according to the format.
3. Download dependency packages
Note: This step needs to be downloaded on a server that cannormally access the Internet. The downloaded dependency package file is shown in Figure 2.
pip download -r requirements.txt -d packages/ -i https://pypi.tuna.tsinghua.edu.cn/simple
Among them: (packages/ is the folder to be generated, which stores the downloaded dependency package files; https://pypi.tuna.tsinghua.edu.cn/simple is the mirror source address).
4. Install dependency packages
After preparing the dependency package, you can install it on the target server that cannot use the pip command to download and install the dependency package.
Before using the command, you need to copy the packsges folder and requirements.txt files to the target server, as follows: requestsDependency package as an example.
pip install --no-index --find-links=./packages -r ./requirements.txt
(where: ./packsges is the path of the dependent package; ./requirements.txt is the list path of the dependent package).
