【问题描述】:
我正在使用pipenv 来处理 Python 包依赖项。
Python 包正在使用两个包(名为 pckg1 和 pckg2),它们依赖于名为 pckg3 的同一包,但来自两个不同的版本。显示依赖树:
$ pipenv graph
pckg1==3.0.0
- pckg3 [required: >=4.1.0]
pckg2==1.0.2
- pckg3 [required: ==4.0.11]
尝试安装依赖项:
$ pipenv install
Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
You can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
Hint: try $ pipenv lock --pre if it is a pre-release dependency.
Could not find a version that matches pckg3==4.0.11,==4.1.0,>=4.1.0 (from -r C:\Users\user\AppData\Local\Temp\pipenv-o7uxm080-requirements\pipenv-hwekv7dc-constraints.txt (line 2))
Tried: 3.3.1, 3.3.2, 3.3.3, 3.4.0, 3.4.2, 4.0.0, 4.0.0, 4.0.1, 4.0.1, 4.0.2, 4.0.2, 4.0.3, 4.0.3, 4.0.4, 4.0.4, 4.0.6, 4.0.6, 4.0.8, 4.0.8, 4.0.9, 4.0.9, 4.0.10, 4.0.10, 4.0.11, 4.0.11, 4.1.0, 4.1.0, 4.1.1, 4.1.1, 4.1.2, 4.1.2, 4.2.1, 4.2.1, 4.3.0, 4.3.0
There are incompatible versions in the resolved dependencies.
按照建议,pip install --skip-lock 可以解决问题,但依赖关系树仍未解决。
我很想告诉Pipenv 覆盖pckg2 的要求,并指定pckg3>=4.1.0。
如何解决?
