更新gcc后bazel“未声明的包含”错误

Question

从 gcc-7.1 更新到 gcc-7.2 后，我收到了很多关于未声明包含标准库头文件的错误。例如

$ bazel build //test:my_test
ERROR: /home/haining/my_project/BUILD:39:1: undeclared inclusion(s) in rule '//test:my_test':
this rule is missing dependency declarations for the following files included by 'test/test_range.cpp':
  '/home/haining/gcc-7.2/include/c++/7.2.0/cstddef'
  '/home/haining/gcc-7.2/include/c++/7.2.0/x86_64-pc-linux-gnu/bits/c++config.h'

  '/home/haining/gcc-7.2/include/c++/7.2.0/new'

... etc ...

我怎样才能解决这个问题

每当你对你的系统做一些 Bazel 不可能知道的事情时，运行bazel clean --expunge. 这只是一种更礼貌的做法rm -rf ~/.cache/bazel:)
