我在Windows 7上用Lyx 2.1.2创建了一个Lyx文档，一切都编译得很好。在升级到Lyx 2.1.3之后，同一文档在编译时出现了许多错误。我注意到它们与浮动数字有关，例如我可以看到的uder视图源：

Figure ref{fig:ErasOfComputingWant (2010)} adopted from citep{Want2010}
illustrates conceptually three eras of modern computing.
The Internet of Things initially thought of as connecting things to
the Internet for the purpose of remote monitoring and control it is
now moving into the concept of ubiquitous and pervasive computing
as it creates an intelligent, invisible network fabric that can be
sensed, controlled and programmed.

**Lyx 2.1.3给出了相应的错误：

I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.
! Extra }, or forgotten endgroup.
<argument> ...gWant (2010)}}{footnotesize par }}

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.*****
如何修复？
一月
感谢您的帮助，尽管我认为Lyx 2.1.3版本可能会因为有问题而从Lyx下载部分删除。至少我不能使用它，我只能使用2.1.2
