[英]Pip Installation - How to lock a python lib version when building a wheel?
Question: How do I force pip wheel building to use a particular package?问题:如何强制 pip 轮构建使用特定的包?
Full background:完整背景:
I have a project with setup.py with a set of libs with versions locked down.我有一个带有 setup.py 的项目,其中包含一组锁定版本的库。
Libs are something like this (shortened for conciseness):库是这样的(为了简洁而缩短):
cffi==1.15.0
<some_other_pkg>=1.0.0
<lots of other packages>
When some_other_pkg installs, pip attempts to build the wheel for this package it uses cffi==1.15.1
.当some_other_pkg安装时,pip 尝试为它使用
cffi==1.15.1
的这个包构建轮子。 I would have expected this to use 1.15.0 when building the wheel given the above.鉴于上述情况,我希望在构建轮子时使用1.15.0 。
This is a problem for me as my server can't run with cffi==1.15.1
.这对我来说是个问题,因为我的服务器无法使用
cffi==1.15.1
运行。
How can I instruct pip to use cffi==1.15.0
in the pip wheel building as part of the pip install requirements.pip ?我如何指示 pip 在 pip 轮构建中使用
cffi==1.15.0
作为 pip install requirements.pip 的一部分?
Further details: using python3, virtualenv, pip, setuptools更多细节:使用 python3、virtualenv、pip、setuptools
Thanks谢谢
I solved this yesterday by doing the following:我昨天通过执行以下操作解决了这个问题:
pip install .
pip install .
in the dir with the setup.py file. The above forced the building of wheels to utilise cibffi==1.15.0 instead of the newer version and so no issues relating to missing unix pkg libffi-devel.以上强制轮子的构建使用 cibffi==1.15.0 而不是较新的版本,因此没有与缺少 unix pkg libffi-devel 相关的问题。
