如何解决Python诗歌依赖错误

Question

当尝试通过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pyproject.toml的示例：

...
[tool.poetry.dependencies]
python = ">=3.6"
...

[tool.poetry.dev-dependencies]
pre-commit = "^2.2.0"
...

我尝试将pyproject中的python版本更改为3.7，但未更改结果。而且，如果我删除了预提交的依赖项，那么另一个依赖项也会出现相同的错误。

我不知道要寻找什么：升级/降级版本，不兼容的版本

正如@Arne在评论中提到的那样，这似乎是一个virtualenv问题。

我以前为另一个项目运行过poetry config virtualenvs.create false，并且配置是在全局级别进行的。运行反向命令poetry config virtualenvs.create true解决了这个问题（也许添加--local以将其设置为单个项目）。
