运行 堆栈构建时如何解释此错误？
How to interpret this error when running stack build?
这是我所做的：
stack new ...
创建了新项目
在 package.yaml
中将 Spock 添加到 dependencies
我 运行 stack build，但收到一个错误建议我向 stack.yaml 添加依赖项，所以我做了
- 将此行添加到
stack.yaml 中的 extra-deps：
extra-deps: - Spock-0.13.0.0@sha256:163ef2698fed8f5801428d8dbe794fd126415a5ff3304b227750fdc4037497be,3745
运行 stack build 再次出现此错误：
Received ExitFailure 1 when running

Standard error:

我不确定如何解释此错误...“字节数不足”？
更新：尝试删除 ~/.stack，没有帮助：

这意味着您的 GHC 包数据库已损坏，是时候 rm -rf ~/.stack + 重建了。
我过去曾通过 运行 同时进行多个 Stack 操作来破坏它，但很难说你是怎么做到的。
接受前更新回答：
rm .stack-workrm -rf ~/.stackstack build
