haskell - 使用 cabal 更新 agda 时出现内存不足情况错误？

Question

我正在尝试升级 agda，出现内存错误。有什么办法可以解决这个问题？

我尝试了 cabal install --ghc-options="+RTS -M600M"--force-reinstalls agda 但是根据类似的问题，这只是给出了一个堆错误。

wmacmil@w:~$ cabal install --force-reinstalls agda
Resolving dependencies...
Warning: The following packages are likely to be broken by the reinstalls:
Agda-2.6.0.1
Continuing even though the plan contains dangerous reinstalls.

This may be due to an out-of-memory condition.

啊，GHC 的内存饥饿是无法饱和的...

对于更大的安装，我通常做的是，几乎不限制 GHC 的 -M(或者可能是总内存的 80%)，但要确保它实际上具有每个进程的所有可用空间，通过将编译限制为单个进程。

cabal install --ghc-options="+RTS -M7G" -j1 --force-reinstalls agda

显然，这会使一切变得非常缓慢，但至少它通常会成功。
