Python - 为 python 2.6.6 版本安装 Argpath 时出现问题

Question

我已经在我的系统中安装了 python2.6.6 的 argpath 包。但是当我尝试运行需要 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。所以我在其他路径（别名 python='/usr/local/bin/python2.6'）中安装了 python 2.6，并且我使用 pip 工具安装了 argparser，如下所示，它说“安装成功”

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

但是当我尝试运行我的 python 脚本时，它仍然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

ImportError: No module named argparse

我在这个问题上坚持了 2 天。请就此向我提出建议。

我自己解决了。其实是我走错路了，

argparser的安装路径：

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

但错误安装在以下路径：

[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

实际上，我是企业用户，并且遇到了代理问题。所以我已经通过使用以下命令解决代理问题。

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

所以我尝试了下面的代理问题，

export https_proxy=<username>:<password>@<proxy url>:<port no> - 如果您的密码有特殊字符，那么您需要进行相应的处理。

所以 pip 安装程序在默认的 Python2.7 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

最后它会在指定目录下安装 argparser 包。但是在这里我也犯了一个错误..

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

现在一切正常。感谢上帝。
