更新cabal时出错 [英] error when updating cabal

问题描述

我无法在Windows 7上更新cabal。当运行 cabal install cabal-install 时，出现以下错误：

I cannot update cabal on windows seven. When running cabal install cabal-install, I get the following error:

Linking C:\Users\sberg\AppData\Local\Temp\Cabal-1.18.1.2-10956\Cabal-1.18.1.2\dist\setup\setup.exe ...
Configuring Cabal-1.18.1.2...
setup.exe: does not exist
Failed to install Cabal-1.18.1.2
cabal: Error: some packages failed to install:
Cabal-1.18.1.2 failed during the configure step. The exception was:
ExitFailure 1
cabal-install-1.18.0.2 depends on Cabal-1.18.1.2 which failed to install.

我找不到关于haskellwiki / cabal faq的任何信息。我错过了什么吗？我正在使用windows的haskell平台版本2013.2.0.0。

I could not find any information on haskellwiki/cabal faq. Am I missing something? I am using the version 2013.2.0.0 of the haskell platform for windows.

推荐答案

我找到了一个解决方法，即运行使用MSYS命令 cabal install cabal-install 。

I have found a workaround, which is to run the command cabal install cabal-install with MSYS.

然而，我注意到在最新的cabal中，很多不存在运行时出错 cabal install --only-dependencies 或 cabal configure 如果您不在MSYS控制台中。

I noticed however that with the newest cabal, I get a lot of does not exist errors when running cabal install --only-dependencies or cabal configure if you are not in a MSYS console.

编辑在我的情况下，它是由本地64位perl安装。重新排序perl&我的道路上的哈斯克尔平台解决了这个问题。

Edit In my case it was caused by a local 64bits perl install. Reordering perl & the haskell platform in my path solved the issue.
