Answer questions jiuqiant

I am wondering if you need to uninstall and install bazel again after your get Xcode and its command line tools. Also, please do bazel clean --expunge to make sure you have a clean start.

It seems like the error message is truncated, I would like to see more error message if possible. Moreover, can you report the version number of your OS, Bazel, clang, and XCode?

Here are some links that may help:
