Question

我已经在我的系统中为python2.6.6安装了argpath包。但是当我尝试运行需要argparser模块的脚本时，仍然会抛出错误＆＃34; ImportError：没有名为argparse的模块＆＃34;

我正在使用Fedora 20，所以默认版本是Python 2.7。所以我已经在其他路径中安装了python 2.6（别名python =＆＃39; /usr/local/bin/python2.6'）并且我已经使用pip工具安装了argparser，如下所示，它说＆＃34;已成功安装＆＃34;

[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，仍然会说出与下面相同的错误

[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
Exception in user code:

ImportError: No module named argparse

我已经坚持了2天这个问题。请建议我。

我刚刚解决了自己。实际上这是我错误的错误路径，

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

其实我是企业用户，我遇到了代理问题。所以我通过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，它将无效。

所以我在下面尝试了代理问题，

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

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，它将在指定目录中安装argparser包。但在这里我也犯了错误。

对我来说，我已指定/usr/local/lib/python2.6来解决问题。

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

现在工作正常......感谢上帝。
