如何解决 Python 诗歌依赖错误
How to solve Python poetry dependency error
尝试使用 Poetry 安装 Python 依赖项时,出现以下错误:
$ poetry install
The currently activated Python version 2.7.15 is not supported by the project (>=3.6).
Trying to find and use a compatible version.
Using python3 (3.7.4)
Skipping virtualenv creation, as specified in config file.
Updating dependencies
Resolving dependencies... (1.7s)
[SolverProblemError]
The current project's Python requirement (>=3.6) is not compatible with some of the required packages Python requirement:
- pre-commit requires Python >=3.6.1
Because no versions of pre-commit match >2.2.0,<3.0.0
and pre-commit (2.2.0) requires Python >=3.6.1, pre-commit is forbidden.
So, because my-proj depends on pre-commit (^2.2.0), version solving failed.
这是我的环境:
$ python3 --version
Python 3.7.4
$ poetry --version
Poetry version 1.0.5
$ pre-commit --version
pre-commit 2.2.0
还有我的样本 pyproject.toml:
...
[tool.poetry.dependencies]
python = ">=3.6"
...
[tool.poetry.dev-dependencies]
pre-commit = "^2.2.0"
...
我试过将pyproject中的python版本改成3.7,但没有改变结果。如果我删除预提交依赖项,我会在另一个依赖项上遇到相同的错误。
我不知道我应该寻找什么:upgrading/downgrading 版本,不兼容的版本
正如@Arne 在评论中提到的,这似乎是一个 virtualenv 问题。
我之前 运行 poetry config virtualenvs.create false
另一个项目,配置是在全局级别设置的。 运行 反向命令 poetry config virtualenvs.create true
解决了问题(也许添加 --local
以将其设置为个别项目)。
