[Mac] gsutil 遇到 Enum not defined 錯誤
Google 的 gsutil 在我的 Mac 上真的是很常遇到問題…
前幾天遇到了 httplib2 版本過舊的問題，
今天遇到的是 Enum not defined:
testuser@localhost ~ $ gsutil Traceback (most recent call last): File "/usr/local/bin/gsutil", line 9, in <module> load_entry_point('gsutil==4.13', 'console_scripts', 'gsutil')() File "/Library/Python/2.7/site-packages/pkg_resources/__init__.py", line 558, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/Library/Python/2.7/site-packages/pkg_resources/__init__.py", line 2682, in load_entry_point return ep.load() File "/Library/Python/2.7/site-packages/pkg_resources/__init__.py", line 2355, in load return self.resolve() File "/Library/Python/2.7/site-packages/pkg_resources/__init__.py", line 2361, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) File "/Library/Python/2.7/site-packages/gslib/__main__.py", line 53, in <module> from gslib import wildcard_iterator File "/Library/Python/2.7/site-packages/gslib/wildcard_iterator.py", line 37, in <module> from gslib.translation_helper import GenerationFromUrlAndString File "/Library/Python/2.7/site-packages/gslib/translation_helper.py", line 25, in <module> from apitools.base.py import encoding File "/Library/Python/2.7/site-packages/apitools/base/py/__init__.py", line 5, in <module> from apitools.base.py.base_api import * File "/Library/Python/2.7/site-packages/apitools/base/py/base_api.py", line 10, in <module> from protorpc import message_types File "/Library/Python/2.7/site-packages/protorpc/message_types.py", line 28, in <module> from . import messages File "/Library/Python/2.7/site-packages/protorpc/messages.py", line 398, in <module> class Enum(six.with_metaclass(_EnumClass, object)): File "/Library/Python/2.7/site-packages/protorpc/messages.py", line 300, in __init__ if not (bases == (object,) or bases == (Enum,)): NameError: global name 'Enum' is not defined
後來在 gsutil 論壇上找到這篇 NameError from protorpc happen in 4.12，
說是 easy_install 裝的 six 模組比較舊，把 pip 裝的新模組遮蓋掉了，
testuser@localhost ~ $ python >>> import six >>> six.__version__ '1.4.1' testuser@localhost ~ $ pip show six Metadata-Version: 2.0 Name: six Version: 1.9.0 Summary: Python 2 and 3 compatibility utilities Home-page: http://pypi.python.org/pypi/six/ Author: Benjamin Peterson Author-email: benjamin@python.org License: MIT Location: /Library/Python/2.7/site-packages Requires:
還沒研究，不曉得 easy_install 和 pip 安裝的各別安裝到哪去了…
照著它上面的解法，用 easy_install 把 six 模組也升到最新版：
sudo easy_install -U six
果真問題就解決了～～ 有空再來研究一下 easy_install 和 pip 吧 XD
