当PyPy和iPython在virtualenv创建的项目中共存时，PyCharm的Python控制台失败了

Question

某些版本信息：

OS: Mac OS X 10.8.4
Python: 2.7.2 (that came with the Mac OS X)
PyPy: 2.0.2
iPython: 0.13.2
PyCharm: 2.5.1

当PyPy和iPython在virtualenv创建的项目中共存时，PyCharm的Python控制台失败了。

我创建了三个虚拟环境项目。我没有激活任何虚拟环境。所以，系统python仍然存在。

环境 - 1：

$ virtualenv -p /path/to/system/installed/python /path/to/sample_1/virtualenv/project
$ /path/to/sample_1/virtualenv/project/bin/pip install ipython

现在，当我在PyCharm中运行python控制台时，它运行正常。 （PyCharm中的解释器设置为/ path / to / sample_1 / virtualenv / project / bin / python）

环境 - 2：

$ virtualenv -p /path/to/pypy /path/to/sample_2/virtualenv/project

现在，当我在PyCharm中运行python控制台时，它运行正常。 （PyCharm中的解释器设置为/ path / to / sample_2 / virtualenv / project / bin / python）

环境 - 3：

$ virtualenv -p /path/to/pypy /path/to/sample_3/virtualenv/project
$ /path/to/sample_3/virtualenv/project/bin/pip install ipython

现在，当我在PyCharm中运行python控制台时，它失败并出现以下错误。 （PyCharm中的解释器设置为/ path / to / sample_3 / virtualenv / project / bin / python）

Process finished with exit code 1

请注意，任何虚拟环境中的bin / python都指向已安装的解释器。例如，/ path / to / sample_3 / virtualenv / project / bin / python指向pypy和/ path / to / sample_1 / virtualenv / project / bin / python指向系统安装的python。

这似乎与this有关。但是，我不确定。

请帮忙。

查看实际的异常消息，这可能是一个潜在的解决方案：

Meanwhile, you should be able to work around the problem by setting
 export TERM="xterm-256color" in the shell from which you execute ipython,
or in your~/.bashrc file, which you then source.
