这是怎么了？
答案 0 :(得分：1)
问题已解决。对于gRPC，我必须将依赖项放在deps = []中。
最后有人给出答案。
我需要在部门中添加“ @com_github_grpc_grpc // :: grpc ++”。
如此愚蠢的错误
答案 1 :(得分：0)
您没有安装grpc本身（如果要构建它，则可能需要sudo make install等价的挡板）
答案 2 :(得分：0)
在您的第一个BUILD文件中，您的cc_grpc_library规则应为
cc_grpc_library(
name = "hello_world",
srcs = ["relative/path/to/hello_world.proto"],
deps = [],
)
请注意，srcs参数中没有冒号。
您的srcs参数以冒号开头，这是用于传递给deps的本地规则依赖项的Bazel语法。对于src自变量，请在每个源文件中使用无冒号的相对文件路径。 bazel example应该会有所帮助。
