我在Pycharm上使用2016.1 CentOS7，我正在测试“Show command line afterwards”，我遇到了这个问题：

AttributeError: 'PyDevTerminalInteractiveShell' object has no attribute 'has_readline'

Answer 1

由于iPython api与iPython版本5的更改，发生此PyCharm问题。在Jetbrains修复此问题之前，还原到早期版本的iPython（版本4）将更正此问题。正如@chenfei发现的那样，这可以通过pip：

来完成

$ pip uninstall ipython
$ pip install ipython==4.2.0

修改

如果你不能等那么久，Jetbrains已经发布了补丁

https://youtrack.jetbrains.com/issue/PY-20013#comment=27-1512407

最终修改

此问题已在PyCharm 2016.2中修复。

Answer 2

我通过安装ipython版本4.2解决了我的问题：

pip uninstall ipython
pip install ipython==4.2.0

Answer 3

我设法解决此问题而不降级iPython 的方式是：

1 - 下载以下补丁：

https://youtrack.jetbrains.com/_persistent/pycharm_ipython5_fix.patch?file=74-327779&c=true

2 - 在PyCharm内，创建一个位于以下位置的新项目：

<PyCharm installation folder>/helpers/pydev/_pydev_bundle/

Pycharm会提示您导入该文件夹上的文件接受。

3 - 点击 VCS 并选择 Apply Patch

4 - 选择您在第1步上下载的文件。

5 - Apply Patch 窗口将打开，单击确定

6 - 重新启动PyCharm

Python控制台现在应该在PyCharm

内部工作

PS：你可以删除你在第2步

上创建的项目文件夹（.idea）

Answer 4

它在Pycharm 2016.2中得到了解决。看这里： https://intellij-support.jetbrains.com/hc/en-us/community/posts/207207329-ipython-5-not-supported-by-Pycharm-s-python-console-
