SageMath:运行`make`在dochtml阶段以ImportError结束

Question

我正在尝试在我的macbook中安装sagemath包。我先输入./configure，然后输入make。下面是最后几行输出。无法调试原因。

Error building Sage.

The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):

The build directory may contain configuration files and other potentially
helpful information. WARNING: if you now run 'make' again, the build
directory will, by default, be deleted. Set the environment variable
SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.

任何帮助都将不胜感激。

Answer 1

为SageMath运行make分两步进行:先运行make build，然后运行make doc。

在您的例子中，make build阶段似乎已经完成，只在make doc阶段出现了问题。这意味着您可能已经有了一个功能性SageMath，但存在文档无法构建的缺点。因此，您可能决定尝试按原样使用它。

关注@John Palmieri，我建议发布到sage-devel或sage-support，以获得调试make失败的帮助。指定发生buid的操作系统(macOS的版本)、buid是从git clone获得的目录启动还是从源tarball启动，以及运行的确切操作顺序将非常有用。

此外，在您下次尝试时，您可能希望在运行make之前将SageMath文件夹移出Downloads文件夹，因为Sage安装在启动一次之后就无法移动(如果移动了Sage，则必须再次运行make才能使用它)。

根据塞缪尔的回答，您可能想要尝试的另一件事是简单地运行make doc-clean，然后再次运行make doc。我发现(在Mac上)有时会有一个奇怪的打饱眼，我永远也找不到，而这通常会过去。
