使用pip3软件包下载另一个Python版本 [英] download with pip3 packages for another python release

问题描述

我拥有一个离网服务器(带有python3.8的Linux x86_64)，我想在其上安装pypi软件包.到目前为止，我从pypi.org手动下载了每个软件包和依赖项.而且很痛苦.

I own an off grid server (linux x86_64 with python3.8) on which I would like to install pypi packages. Up to now, I download manually each package and dependencies from pypi.org. And it is painful.

我想使用 pip3下载功能，该功能非常适合我的需求！除了我从中下载的平台有很大不同(带有python3.6的win_amd64).由于我想获取 numpy-1.18.5-cp38-cp38-manylinux1_x86_64.whl ，因此我尝试了:

I would like to use pip3 download feature which is perfect for my needs ! Except the platform I download from is very different (win_amd64 with python3.6). Since I want to get numpy-1.18.5-cp38-cp38-manylinux1_x86_64.whl, I tried :

pip3 download --verbose --only-binary=:all: --abi=cp38 --platform=manylinux1_x86_64 numpy

然后，检查详细日志，找到与预期车轮相对应的行，我得到一个与该Python不兼容 ...当然不是！

And, checking the verbose log, for the line which correspond to the expected wheel, I get a it is not compatible with this Python... Of course it isn't !

即使不是我所下载平台的正确文件，我如何强制pip3下载适当的 .whl 文件?

How could I force pip3 to download the appropriate .whl file even if it is not the correct one for the platform I download it from ?

推荐答案

如果要传递-abi ，则还必须传递-python-version ，因此 pip 可以构建正确的平台标记.这应该有效(未试用):

If you're passing --abi, you have to also pass the --python-version so pip can build the correct platform tag. This should work (untested):

$ pip3 download --only-binary=:all: --python-version=38 --abi=cp38 --platform=manylinux1_x86_64 numpy

尽管承认， pip下载并非可靠，例如解决环境标记和内容时.

Although admitted, pip download is anything but reliable, e.g. when it comes to resolving environment markers and stuff.
