無法導入的ReadLine在Django殼蟒蛇

Question

我在CentOS 6的Linux

當我嘗試這個

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 
>>> 

我嘗試安裝與PIP蟒蛇的ReadLine和我得到這個

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... 

我應該怎麼辦

編輯：

我想這也

[myhost]$ virtualenv/bin/python2.7 
Python 2.7.3 (default, Nov 23 2012, 18:02:22) 
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2

>>> import readline 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ImportError: No module named readline 
>>> 

我試過所有

(virtualenv)[aaaaaa]$ source virtualenv/bin/activate 
(virtualenv)[aaaaaa]$ virt 
virtualenv/    virtualenv-clone   virtualenvwrapper.sh 
virtualenv-2.7    virtualenvwrapper_lazy.sh virt-what 
(virtualenv)[aaaaaa]$ virtualenv/bin/pip 
pip  pip-2.7 
(virtualenv)[aaaaa]$ virtualenv/bin/pip 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

我嘗試了所有vitual env和激活爲好。而我又得到同樣的錯誤

Answer 1

您需要actually activate the environment you want to use，不只是從視覺環境運行蟒蛇二進制bin文件夾：

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

Answer 2

，對我工作的一種解決方法是重新安裝的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
