我正在运行 Ubuntu 16.04 并使用 texlive-full apt 包。我在 TeXmaker 和 TeXstudio 中尝试过这个，在两者中都遇到了同样的错误，我在 Overleaf 上尝试过它并且运行正常，所以问题一定出在 TeX Live 上。
我可以导入 setspace 包而不会出现任何错误或警告，但如果我尝试使用任何 setspace 方法，编译器会说它们未定义。以下是示例和日志文件的相关部分。
我只是不知道为什么这个包在 Overleaf 上运行，却在我的计算机上不运行。

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

You're in trouble here. Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.

意思是您的文件夹中有 的本地副本setspace.sty。这可能是 的旧副本setspace或修改版本。
尝试重命名本地副本，看看是否有帮助。
