Question

我正试图在我的macbook上安装sagemath软件包。我进去了 ./configure后跟make。这是最后几个 输出行。无法调试原因。你知道吗

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。你知道吗

Answer 1

为SageMath运行make分两步进行：make build 接着是make doc。你知道吗

在您的例子中，make build阶段似乎已经完成， 只有在make doc阶段才有问题。 这意味着你可能已经有了一个函数数学， 有一个缺点就是文档无法构建。 所以你可能会决定按原样使用它。你知道吗

在@John Palmieri之后，我建议发布到sage-devel 或sage支持来获得调试make失败的帮助。会的 用于指定发生错误的操作系统 （什么版本的macOS），如果buid是从目录启动的 通过git clone或源tarball获得，具体是什么 操作序列已运行。你知道吗

另外，在下一次尝试时，您可能希望移动SageMath 在运行make之前从下载文件夹中取出文件夹，因为 Sage安装启动一次后就不能移动 （如果移动了Sage，则必须再次运行make才能使用）。你知道吗

Answer 2

根据Samuel的回答，您可能想尝试的另一件事是只运行make doc-clean，然后再运行make doc。我发现（在Mac电脑上）有时会有一个奇怪的打嗝，我永远也找不到，这通常会过去。你知道吗
