Python - 安裝Argpath for python 2.6.6版本中的問題版本

Question

我已經在我的系統中爲python2.6.6安裝了argpath包。但是當我嘗試運行需要argparser模塊的腳本時，仍然出現錯誤「ImportError：No module named argparse」

我使用的是Fedora 20，所以默認版本是Python 2.7。因此，我已以一些其它路徑（別名蟒=「的/ usr/local/bin中/ python2.6的」）安裝蟒2.6和我已經安裝argparser使用PIP工具，如下所示，並將其所述「安裝成功」

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

Cleaning up... 

但是，當我嘗試運行我的python腳本，它仍然說着同樣的錯誤如下

[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

    import fileinput, argparse, json, csv 
ImportError: No module named argparse

我已經被困2天這個問題。請在此建議我。

我剛剛解決了我自己。其實這是我的錯誤與錯誤的路徑，argparser

安裝路徑：安裝在以下路徑

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

卻誤：

[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 

其實我是一個企業用戶和我有代理問題。所以我通過使用下面的命令解決了代理問題。

pip install -U argparser - 如果您的網絡中有代理設置，它將不起作用。

所以我已經嘗試下面一個是代理問題，

export https_proxy=<username>:<password>@<proxy url>:<port no> - 如果你的密碼有特殊字符，那麼你就需要相應地處理它。

所以pip安裝程序在默認的Python2.7位置安裝了argparser。

然後我已修改命令等下面，

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

最後它將在指定的目錄安裝argparser包。但在這裏，我也犯了一個錯誤的道路..

對我來說，我指定/usr/local/lib/python2.6得到它解決。

所以最後的命令是：

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

現在它工作正常..謝謝上帝。
