Question

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
==> Cleaning build stage [nalu@master%clang@8.1.0-apple build_type=RelWithDebInfo ~openfast arch=darwin-sierra-x86_64 /5vijzp7]

     33    
     34            self.stage.cache_local()

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 中找不到版本控制规范。

这意味着什么？我该如何解决这个问题？

Answer 1

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

中列出的校验和不匹配

在这种情况下，发生的事情是您下载了 yaml-cpp，然后 GitHub 更改了它们的自动 tarball 生成算法，然后 package.py 中的校验和被更新到上游。有关详细信息，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 删除所有缓存的 tarball。

P.S。 Spack 目前在 Whosebug 上不是很活跃。你最好在 GitHub or Slack.
