windows bpython 的安装流程

刚开始学习python的时候使用的ipython解释器，挺好用的，后来发现bpython功能更强大，linux系统中安装基本没啥问题，不过在windows下安装倒是不容易啊。使用google搜了一下， 发现bpython-curses这个命令可以运行，参考了这个网址的https://github.com/bpython/bpython/issues/509官方对window安装的说明：https://docs.bpython-interpreter.org/windows.html

下面我整理下正确的安装方法。

1.先安装bpython

C:\Users\Administrator>pip install bpython      #请确认你的pip已经安装并且配置到环境变量path中去了。 这里pip可以换成easy_install, conda 

2.测试下bpython,提示No module named ‘_curses‘

C:\Users\Administrator>bpython
Traceback (most recent call last):
  File "e:\program files\python36\lib\runpy.py", line 193, in _run_module_as_mai
n
    "__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", line
4, 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.安装cursers包

#去这个网站找到对应版本的curses下载下来,http://www.lfd.uci.edu/~gohlke/pythonlibs/#curses ,这个包暂时pip没法去下载它，需要手工下载后再使用pip 安装
C:\Users\Administrator>pip install E:\tmp\curses-2.2-cp36-cp36m-win_amd64.whl

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

C:\Users\Administrator>bpython
Traceback (most recent call last):
  File "e:\program files\python36\lib\runpy.py", line 193, in _run_module_as_mai
n
    "__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", line
4, 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 ioctl
ModuleNotFoundError: No module named ‘fcntl‘

5.修改启动bpython的位置

我的bpyton的安装位置是在E:\Program Files\Python36\Scripts ，我们不启动bpython 启动bpython-curses试试。

C:\Users\Administrator>bpython-curses     #可以运行了。

6.命令重命名下

进入我们的E:\Program Files\Python36\Scripts目录，把bpython.exe,bpython-curses.exe先备份一下，然后删除bpython.exe, 修改bpython-curses.exe 为bpython.exe

7.在测试下吧,如果不可以，你先关闭终端，重新打开一下试试。

可以愉快的使用bpython了。
