在OSX上安装Tensorflow - clang: 错误：链接器命令以退出码1失败

Question

我正在尝试从源代码安装适用于OSX（Mojave 10.14.3）的Tensorflow，并在终端中按照https://www.tensorflow.org/install/source上所述运行bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package时遇到以下错误：

Undefined symbols for architecture x86_64:
  "_PyModule_AddIntConstant", referenced from:
      _PyInit__api_implementation in api_implementation.o
  "_PyModule_Create2", referenced from:
      _PyInit__api_implementation in api_implementation.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Target //tensorflow/tools/pip_package:build_pip_package failed to build
Use --verbose_failures to see the command lines of failed build steps.

根据stackoverflow上类似（但不完全相同）的帖子，这似乎与Xcode有关。我已经尝试重新安装Xcode命令行工具和更新Xcode本身，但无济于事。另外，我没有办法更改代码中的任何内容。感谢您的帮助！

这个问题已经在Bazel的最新版本中得到解决。

修复此问题的代码如下：
