【问题描述】：

我在 Centos 6 Linux 上

当我尝试这个时

Python 2.7.3 (default, Nov 23 2012, 18:02:22)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> import readline
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ImportError: No module named readline
>>>

我尝试使用 pip 安装 python readline，我得到了这个

 virtualenv/bin/pip-2.7 install readline
Requirement already satisfied (use --upgrade to upgrade): readline in ./virtualenv/lib/python2.7/site-packages/readline-6.2.4.1-py2.7-linux-x86_64.egg
Cleaning up...

我该怎么办

编辑：

我也试过了

[myhost]$ virtualenv/bin/python2.7

我都试过了

我尝试了所有的虚拟环境并激活了。但是我又得到了同样的错误

【问题讨论】：

你到哪儿了吗？我需要创建一个 virtualenv，我无法让它在系统范围内工作。

标签： python django shell readline

【解决方案1】：

您需要actually activate the environment you want to use，而不仅仅是从环境bin 文件夹中运行python 二进制文件：

$ source /path/to/envirn/bin/activate
$ pip install readline
$ python 
> import readline

【解决方案2】：

对我有用的解决方法是重新安装 readline：

$ source /path/to/env/bin/activate
$ pip uninstall -y readline
Uninstalling readline-6.2.4.1:
  Successfully uninstalled readline-6.2.4.1
$ pip install readline
Collecting readline
Installing collected packages: readline
Successfully installed readline-6.2.4.1
