TensorFlow : Error building pip package

I am trying to build TensorFlow from source. After configuring the installation, when I try to build to the pip package with the following command,

$ bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package

I get the following error message:

ERROR: /workspace/tensorflow/core/BUILD:1312:1: Executing genrule //tensorflow/core:version_info_gen failed: bash failed: error executing command

What's going wrong?

I encountered this error even though I had git in my PATH variable. I got a hint from https://stackoverflow.com/a/5659249/212076 that the launched subprocess was not getting the PATH variable.

The solution was to hard-code the git command in <ROOT>\tensorflow\tensorflow\tools\git\gen_git_source.py by replacing 

val = bytes(subprocess.check_output([
        "git", str("--git-dir=%s/.git" % git_base_path),
        str("--work-tree=" + git_base_path), "describe", "--long", "--tags"
    ]).strip())

with 

val = bytes(subprocess.check_output([
        "C:\Program Files (x86)\Git\cmd\git.cmd", str("--git-dir=%s/.git" % git_base_path),
        str("--work-tree=" + git_base_path), "describe", "--long", "--tags"
    ]).strip())

Once this got fixed I got another error: fatal: Not a git repository: './.git'. I figured the tensorflow root folder was the one that should have been referenced and so I edited <ROOT>\tensorflow\tensorflow\tools\git\gen_git_source.py to replace

git_version = get_git_version(".")

with

git_version = get_git_version("../../../../")

After that the build was successful.

NOTE: Unlike OP, my build platform was Windows 7 64 bit

Your build appears to be encountering an error in 

tensorflow/tools/git/gen_git_source.py

at line 152. At this stage in the build the script is trying to get the git version number of your tensor flow repo. Have you used git to check out your tensor flow repo? Are the .git files present in the /tensorflow/ root dir? Maybe you need to update your version of git?
