我最近将MacBook Pro升级为Yosemite，而且我现在无法从源代码构建Rust。我跑的时候
$ ./configure
$ make && sudo make install
它似乎构建良好，但挂在此行的安装
rustdoc: doc/rustc/index.html
并最终输出此错误：
task '<main>' failed at 'failed to generate documentation: couldn't open file (permission denied (Permission denied); path=doc/implementors/graphviz/trait.GraphWalk.js; mode=open; access=read)', /Users/Raevynheart/Code/rust_projects/rust/src/librustdoc/lib.rs:246
make: *** [doc/rustc/index.html] Error 101
make: *** [install] Error 2
我发现这可能与issue有关，但我不确定如何继续。谢谢你的帮助。

对于遇到类似问题的人来说，这对我有用。如果您运行make help，则会向您显示make命令的选项。其中之一是：
# * clean - Clean the build repertory. It is advised to run this
# command if you want to build Rust again, after an update
# of the git repository.
运行sudo make clean然后make && sudo make install让Rust准备好再次滚动。
