Question

我正在尝试使用pipenv安装探矿器。但是由于astroid版本冲突导致安装失败。 Astroid是探矿者的子依赖项。自2018年7月15日发布astroid 2.0以来，此故障就开始了。在此之前，该版本没有抱怨并成功

  You can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.

在以上警告中，版本限制存在冲突。 <2.0，> = 2.0.0。但是，当我检查pipenv图时，没有任何依赖项具有> = 2.0.0的星形限制

Answer 1

回答我自己的问题：）

可以通过以下方法找出问题所在。

即使“ pipenv图”没有提及任何限制astroid> = 2.0.0的依赖项，但如果我执行“ pipenv lock --verbose”，则它清楚地表明pylint-plugin-utils版本0.4希望astroid能够是> = 2.0.0

根据我的软件包，pylint-plugin-utils应该> = 0.2.6。因此，我在下面的子句中添加了子依赖项

[dev-packages]
astroid = "==1.6.5"
pylint-plugin-utils = "==0.2.6"
prospector = "*"

我特别提到了astroid版本，因为如果没有安装，那么它将安装2.0版，而其他一些子软件包希望它是<2.0

由于astroid版本冲突，使用pipenv安装探矿器失败
