[英]How to resolve Python package dependencies with pipenv?
我正在使用pipenv
来处理 Python package 依赖项。
Python package 使用两个包(名为pckg1
和pckg2
),它们依赖于同一个名为 pckg3 的pckg3
,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.
正如建议的那样, 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?
我不断收到该错误。 每次清除锁定文件中的缓存都非常有效。
$ pipenv lock --pre --clear
你不能。 目前, pipenv
不提供任何显式覆盖需求约束的内容。
作为一种解决方法,您可以将要覆盖的依赖项放在dev-packages
因为这些依赖项将被packages
覆盖,因此此Pipfile
应安装pckg3>=4.1.0
:
# Pipfile
...
[packages]
pckg1 = "==3.0.0"
[dev-packages]
pckg2 = "==1.0.2"
如果您现在锁定并安装:
$ pipenv lock --dev
$ pipenv install --dev
要求==4.0.11
将被>=4.1.0
覆盖。 如果您问我,这很丑陋,因为这不是开发包的用途,而且您正在更改项目中pckg2
依赖项的角色,但我在这里看不到任何更好的方法。
当 pipfile 上有未完成的例程时,这会起作用。
一旦我犯了一个错误并运行
pipenv install codecove # With an 'e' at the end
并且 pipenv 一直试图完成安装但没有成功,因为 lib 不存在。 我解决了它:
pipenv uninstall codecove
并在之后安装了 codecov。
我试着跑
pipenv lock --clear
pipenv lock --pre --clear
但只有在卸载了错误名称的 lib 后,我才成功。
我有与google-cloud-core
类似的问题。
$ pipenv lock

Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
First try clearing your dependency cache with $ pipenv lock --clear, then try the original command again.
Alternatively, 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.

它被解决了
如果您收到如下错误:
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
✘ Locking Failed!
对我来说,这是因为底层虚拟环境没有引用我的当前目录。
我通过将内容移动到新目录并删除旧目录解决了这个问题。
我还必须删除Pipfile
和Pipfile.lock
但我不确定是否有必要。
它发生在我身上,我正在使用 Visual Studio Code 并且能够摆脱它:
然后尝试为虚拟文件夹安装缺少的依赖项,一切顺利,它对我有用。
如果你遇到了Locking Failed!
错误:
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
✘ Locking Failed!
清除pipfile.lock
上的缓存,卸载您的软件包并重新启动 VM对我来说很有效。
尝试:
pipenv uninstall *YourPackage*
pipenv uninstall *YourPackage* --dev ##(if relevant to your package)
pipenv lock --clear
停止并销毁虚拟机
重启虚拟机
希望这可以帮助!
我对 glob 模块有类似的问题。 我从 Pipfile 中删除了glob = "*"
,之后它工作正常。
错误:
bash-4.2# pipenv lock --clear
Locking [dev-packages] dependencies…
✔ Success!
Locking [packages] dependencies…
✘ Locking Failed!

在使用 VS Code 的 Windows 10 上,通过在 Powershell 中运行 pipenv,我得到了一个全新的安装。 我还删除了以前尝试的所有痕迹(新目录删除了以前的 venvs)。
这里没有什么对我有用。 最终解决了这个问题:
pip uninstall pipenv
pip install pipenv
pip install -U pipenv
在 Ubuntu 21.04 - Hirsute Hippo - python 版本 3.9.5 上为我解决
此命令安装了这些软件包:
在 virtualenv 中更新pip
对我有用: py -m pip install --upgrade pip
这也可能是因为您有一个旧的 pipenv 环境,您需要在创建新环境之前清理它。
pipenv --rm
pipenv install
pipenv lock

pipenv 安装 --clean
vi Pipfile 并删除有问题的包。 为我工作得很好。
