Bazel 报错：/tmp/external/gcc_toolchain_x86_64_files/bin/x86_64-linux-gcc： No such file or directory

在测试bazel编译cpp项目时，遇到一个问题：

$bazel build //main:hello-world
Starting local Bazel server and connecting to it...

很神奇的是，曾经对该项目的编译是能正常进行的，而在未修改任何代码的情况下，这个错误出现在了某次编译（和之后）。

在github上找到一个issue：https://github.com/bazelbuild/bazel/issues/20533
按照讨论，在指令后添加--sandbox_add_mount_pair=/tmp指令能修复这个问题。
