剛開始學習python的時候使用的ipython解譯器，挺好用的，後來發現bpython功能更強大，linux系統中安裝基本沒啥問題，不過在windows下安裝倒是不容易啊。使用google搜了一下， 發現bpython-curses這個命令可以運行，參考了這個網址的https://github.com/bpython/bpython/issues/509官方對window安裝的說明：https://docs.bpython-interpreter.org/windows.html

下面我整理下正確的安裝方法。

1.先安裝bpython

C:\Users\Administrator>pip install bpython      #請確認你的pip已經安裝並且配置到環境變數path中去了。 這裡pip可以換成easy_install, conda 

2.測試下bpython,提示No module named ‘_curses‘

C:\Users\Administrator>bpythonTraceback (most recent call last):  File "e:\program files\python36\lib\runpy.py", line 193, in _run_module_as_main    "__main__", mod_spec)  File "e:\program files\python36\lib\runpy.py", line 85, in _run_code    exec(code, run_globals)  File "E:\Program Files\Python36\Scripts\bpython.exe\__main__.py", line 5, in <module>  File "e:\program files\python36\lib\site-packages\bpython\curtsies.py", line 9, in <module>    import curtsies  File "e:\program files\python36\lib\site-packages\curtsies\__init__.py", line4, in <module>    from .window import FullscreenWindow, CursorAwareWindow  File "e:\program files\python36\lib\site-packages\curtsies\window.py", line 11, in <module>    import blessings  File "e:\program files\python36\lib\site-packages\blessings\__init__.py", line 5, in <module>    import curses  File "e:\program files\python36\lib\curses\__init__.py", line 13, in <module>    from _curses import *ModuleNotFoundError: No module named ‘_curses‘

3.安裝cursers包

#去這個網站找到對應版本的curses下載下來,http://www.lfd.uci.edu/~gohlke/pythonlibs/#curses ,這個包暫時pip沒法去下載它，需要手工下載後再使用pip 安裝C:\Users\Administrator>pip install E:\tmp\curses-2.2-cp36-cp36m-win_amd64.whl

4.測試bpython，提示 No module named ‘fcntl‘

C:\Users\Administrator>bpythonTraceback (most recent call last):  File "e:\program files\python36\lib\runpy.py", line 193, in _run_module_as_main    "__main__", mod_spec)  File "e:\program files\python36\lib\runpy.py", line 85, in _run_code    exec(code, run_globals)  File "E:\Program Files\Python36\Scripts\bpython.exe\__main__.py", line 5, in <module>  File "e:\program files\python36\lib\site-packages\bpython\curtsies.py", line 9, in <module>    import curtsies  File "e:\program files\python36\lib\site-packages\curtsies\__init__.py", line4, in <module>    from .window import FullscreenWindow, CursorAwareWindow  File "e:\program files\python36\lib\site-packages\curtsies\window.py", line 11, in <module>    import blessings  File "e:\program files\python36\lib\site-packages\blessings\__init__.py", line 7, in <module>    from fcntl import ioctlModuleNotFoundError: No module named ‘fcntl‘

5.修改啟動bpython的位置

我的bpyton的安裝位置是在E:\Program Files\Python36\Scripts ，我們不啟動bpython 啟動bpython-curses試試。

C:\Users\Administrator>bpython-curses     #可以運行了。

6.命令重新命名下

進入我們的E:\Program Files\Python36\Scripts目錄，把bpython.exe,bpython-curses.exe先備份一下，然後刪除bpython.exe, 修改bpython-curses.exe 為bpython.exe

7.在測試下吧,如果不可以，你先關閉終端，重新開啟一下試試。

 可以愉快的使用bpython了。
