python-3.x - 由于 astroid 版本冲突，使用 pipenv 安装 prospector 失败

Question

我正在尝试使用 pipenv 安装 prospector。但是由于astroid中的版本冲突导致安装失败。 Astroid 是 prospector 的子依赖。自 2018 年 7 月 15 日发布 astroid 2.0 以来，此故障开始。在此之前，构建没有提示并成功

在上面的警告中，存在版本限制冲突。 <2.0，>=2.0.0。但是当我检查 pipenv 图时，没有一个依赖项对 astroid 有 >=2.0.0 的限制

Answer 1

回答我自己的问题:)

能够通过以下方法找出问题。

即使“pipenv 图”没有提到任何限制 astroid >=2.0.0 的依赖项，如果我执行“pipenv lock --verbose”，它清楚地表明 pylint-plugin-utils 版本 0.4 期望 astroid >=2.0.0

根据我的包，pylint-plugin-utils 应该 >=0.2.6。因此，我在 piffle 中添加了子依赖项，如下所示

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

我特别提到了 astroid 版本，因为如果不是，它会安装 2.0 版，而其他一些子包期望它是 <2.0
