haskell-dev - 可能损坏

Question

上下文： 我正在尝试按照 here. Below are the messages I'm seeing in Powershell which don't at all match what I'm seeing @3:10 列出的步骤安装 Haskell 平台，这些人成功地执行了安装步骤.下面一行似乎暗示依赖关系被破坏了......

haskell-dev v0.0.1 [Approved] - Possibly broken

我看到有从旧式 haskell-平台安装程序 升级到 haskell-dev 安装程序的说明 我已经关注了。我想在某些时候我确实在这台机器上安装了旧版本的 Haskell。然而，按照升级旧式安装程序的说明进行操作似乎不起作用。

运行安装说明时我看到的内容：

PS C:\Windows\system32> choco install haskell-dev
Chocolatey v0.10.15
Installing the following packages:

安装成功后别人看到的：

问题：我做错了什么？如果我确实还有 Haskell 的旧发行版，我需要卸载我需要遵循哪些步骤才能正确 find/uninstall -- 然后通过 [=25= 重新安装新版本]haskell-dev 安装程序？我应该恢复尝试使用旧的分期付款方法还是（正如我猜测的那样）是否有充分的理由弃用？

Answer 1

我在安装时遇到了同样的挑战。

尝试： > choco 安装 haskell-dev --force --force-dependencies

强制依赖对我有用。

使用 --force，您不会在已安装的实例上收到错误消息。

测试前不要忘记> refreshenv。
