1322220 - Cannot use --help in js/src/configure causing ImportError: No module named which

Status: RESOLVED DUPLICATE of bug 1322025

(Firefox Build System :: General, defect)

Description

[Sander Mathijs van Veen]

I'm not able to use --help as an argument for the configure script in js/src/. It crashes because the generated code cannot find the module 'which'.

smvv@splendo ~/work/leaningtech/mozilla-central/js/src $ rm -rf obj-optimized; mkdir obj-optimized; (cd obj-optimized; CC=clang CXX=clang++ ../configure --help)

ImportError: No module named which


The file which.py does exist here:
smvv@splendo ~/work/leaningtech/mozilla-central/js/src $ rgrep  WhichError ~/work/leaningtech/mozilla-central

/home/smvv/work/leaningtech/mozilla-central/python/which/which.py:243:    If no match is found for the command, a WhichError is raised.
/home/smvv/work/leaningtech/mozilla-central/python/which/which.py:248:        raise WhichError("Could not find '%s' on the path." % command)

However, normal builds (e.g. --enable-optimize; or --enable-debug --disable-optimize) do work as expected.
