我想用 spack 安装 nalu。我的安装失败并显示一条神秘的错误消息：

$ spack clean nalu

我试图转到有问题的文件夹并检查它预期的提交，但我在/Users/kilojoules/spack/var/spack/stage/yaml-cpp-0.5.3-x7shbh5adkjvzxrjmfdlppt3ka5v6moy.

这意味着什么？我该如何解决这个问题？

此错误消息表示 Spack 下载了yaml-cpp-0.5.3.tar.gztarball，但此 tarball 的校验和与package.py.

在这种情况下，发生的事情是您下载了，然后 GitHub 更改了他们的自动 tarball 生成算法，然后上游更新yaml-cpp了 中的校验和。package.py有关更多信息，请参阅https://github.com/spack/spack/pull/6924。

要解决您的问题，请手动删除 tarball 或运行spack clean --downloads以删除所有缓存的 tarball。

PS Spack 目前在 StackOverflow 上不是很活跃。你最好在GitHub或Slack上提问。
