Thesisdown无法编织PDF：文件错误（con，“ r”）：无法打开连接

Question

我正在按照https://github.com/ismayc/thesisdown上的说明进行操作，但是在尝试编织时会收到以下消息：

Quitting from lines 2-64 (thesis.Rmd) 
Error in file(con, "r") : cannot open the connection
Calls: <Anonymous> ... withVisible -> eval -> eval -> paste -> readLines -> file
In addition: Warning message:
In file(con, "r") :
  cannot open file 'C:/Users/mmazor/Documents/projects/inProgress/unequalVarianceDiscrim/Chudi/thesisdownUCL/prelims/00-abstract.Rmd': No such file or directory
Execution halted

我在做什么错了？

谢谢！
