Python 2.6 ImportError: No module named argparse
提问by user3236698
I'm trying to run git-cola from Red Hat Enterprise Linux Server release 6.5 and receive:
我正在尝试从 Red Hat Enterprise Linux Server 6.5 版运行 git-cola 并收到：
Traceback (most recent call last):
File "....../bin/git-cola", line 24, in <module>
from argparse import ArgumentParser
ImportError: No module named argparse
I think I have all of the required packages installed:
我想我已经安装了所有必需的软件包：
* git-1.7.1-3.el6_4.1.x86_64
* python-2.6.6-51.el6.x86_64
* PyQt4.x86_64 0:4.6.2-9.el6
* /usr/lib/python2.6/site-packages/argparse-1.2.1-py2.6.egg
I read in other blogs that there may be a problem with Python 2.6 and may need to move to 2.7.
我在其他博客中读到 Python 2.6 可能存在问题，可能需要迁移到 2.7。
Additional information - @iljau noticed that argparse is in a 32 bit lib, while the rest of python is in 64 bits. I would have expected that:
附加信息 - @iljau 注意到 argparse 是 32 位库，而 python 的其余部分是 64 位。我会期望：
easy_install argparse
would have sorted this out and installed the 64 bit version.
本来可以解决这个问题并安装 64 位版本。
Additional question: Does anyone know how to install the 64 bit version of argparse. It is not apparent to me from searching the internet. I will continue looking.
附加问题：有谁知道如何安装 64 位版本的 argparse。我在互联网上搜索并不明显。我会继续寻找。
I installed argparse by downloading the tar file and
我通过下载 tar 文件安装了 argparse
python setup.py install
However, it still installed it in the lib rather than lib64 path - and it looks like a 64 bit install. So something else must be the problem in referencing argparse properly. I don't know Python enough to debug it, but I suspect that git-cola needs some work for Python 2.6.
但是，它仍然将它安装在 lib 而不是 lib64 路径中 - 它看起来像 64 位安装。因此，正确引用 argparse 一定是其他问题。我不太了解 Python 来调试它，但我怀疑 git-cola 需要为 Python 2.6 做一些工作。

As a simple solution copy argparse.pyfrom https://code.google.com/p/argparse/source/browse/argparse.pyto your project folder.
作为argparse.py从https://code.google.com/p/argparse/source/browse/argparse.py复制到您的项目文件夹的简单解决方案。
And indeed, for Python 2.6 argparseneeds to be installed separately.
事实上，Python 2.6argparse需要单独安装。
From: https://pypi.python.org/pypi/argparse

As of Python >= 2.7 ..the argparse module is maintained within the Python standard library. For users who still need to support Python < 2.7 ..it is also provided as a separate package, which ..also supports older Python versions.
对于Python> = 2.7的..的argparse模块Python标准库中维护。对于仍然需要支持 Python < 2.7 .. 的用户，它也作为单独的包提供，它..也支持旧的 Python 版本。
But even after you install argparse, it may refuse to work for some mysterious reasons.
但即使在您安装之后argparse，它也可能会因为一些神秘的原因而拒绝工作。

The new packages were installed in the path:
新软件包安装在路径中：
/usr/lib/python2.6/site-packages
Installing them with sudo left the newly installed directories and files unreadable by all. A recursive chmod to open all the installed paths as readable to all solved the problem:
使用 sudo 安装它们会使新安装的目录和文件无法被所有人读取。一个递归的 chmod 来打开所有已安装的路径，因为所有人都可读，解决了这个问题：
chmod -R u+rwX,go+rX,go-w <new directories and files>

I had the same problem on RHEL6 and the solution was installing the package python-argparse.noarch:
我在 RHEL6 上遇到了同样的问题，解决方案是安装软件包python-argparse.noarch：
yum install python-argparse.noarch
then everything was fine.
然后一切都很好。
