Python-Python2.6.6版本的Argpath安装问题

Question

我已经在系统中安装了python2.6.6的argpath包。但当我尝试运行需要argparser模块的脚本时，仍然抛出错误"ImportError:No module named argparse"

我使用的是Fedora 20，所以默认版本是Python 2.7。因此，我在其他路径中安装了python2.6（别名python='/usr/local/bin/python2.6'），并使用pip工具安装了argparser，如下所示，它显示"已成功安装"

[root@127 python2.6]# pip install --target=/usr/bin/Python2.6/lib/python2.6/ argparse

但当我尝试运行我的python脚本时，它仍然会说与下面相同的错误

[root@127 python2.6]# python /home/rajamm/python_scripts/json2csv.py -f /home/rajamm/python_scripts/cvl.json -o /home/rajamm/python_scripts/cvl.csv

这个问题我已经坚持了两天了。请就此向我提出建议。

我自己刚下定决心。事实上这是我的错误，错误的路径，

argparser的安装路径：

[root@127 python2.6]# pwd
/usr/local/lib/python2.6
[root@127 python2.6]# 
[root@127 python2.6]# 

但是错误地安装在以下路径中：

[root@127 python2.6]# cd /usr/local/bin/ (Wrong one)
[root@127 bin]# ls -ltr | grep arg
-rwxr-xr-x. 1 root root   87791 Sep 22 17:40 argparse.py
-rwxr-xr-x. 1 root root   61546 Sep 22 17:56 argparse.pyc

事实上，我是一个公司用户，我有一个代理问题。因此，我使用以下命令解决了代理问题。

pip install -U argparser-如果您的网络中有代理设置，它将不起作用。

所以我已经尝试了以下一个代理问题，

export https_proxy=<username>:<password>@<proxy url>:<port no>-如果你的密码有特殊字符，那么你需要相应地处理它。

因此，pip安装程序在Python2.7的默认位置安装了argparser。

然后我修改了如下命令，

pip install --target=/usr/bin/Python2.6/lib/python2.6/ argparse

最后，它将在指定的目录中安装argparser包。但我在这条路上也犯了一个错误。。

对我来说，我指定了/usr/local/lib/python2.6来解决它。

所以最后的命令是：

1. export https_proxy=<username>:<password>@<proxy url>:<port no>
2. pip install --target=/usr/local/lib/python2.6/ argparse

现在运行良好。。感谢上帝。
