c++ - 升级 Visual Studio 后 Bazel 不再工作

Question

我最近升级了系统上的 Visual Studio，bazel build ... 不再有效。例如，

C:\Users\marki\plasty>bazel build labeling:semantic_seg
INFO: Analyzed target //labeling:semantic_seg (0 packages loaded, 0 targets configured).
INFO: Found 1 target...
ERROR: C:/users/marki/plasty/util/BUILD:59:1: C++ compilation of rule '//util:image' failed (Exit -1). Note: Remote connection/protocol failed with: execution failed

目录 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.21.27702 在我的系统上不存在(不再？)。但是，我找到了目录 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105。但是我不确定我需要在 Bazel 中更改什么设置才能使其使用新目录。

找到这个话题后https://github.com/bazelbuild/bazel/issues/8589 ，我将环境变量 BAZEL_VC_FULL_VERSION 设置为 14.23.28105，这似乎解决了这个问题。
