centos环境python3.6下bpython的安装

centos环境python3.6下bpython的安装

注意：python3.6下通过python get-pip.py安装的pip可执行文件名为pip3

pip3 install bpython

......

Successfully installed blessings-1.6.1 bpython-0.17.1 certifi-2018.1.18 chardet-3.0.4 curtsies-0.3.0 greenlet-0.4.13 idna-2.6 pygments-2.2.0 requests-2.18.4 six-1.11.0 typing-3.6.4 urllib3-1.22 wcwidth-0.1.7

貌似安装成功，但是运行bpython报错：

ModuleNotFoundError: No module named '_curses'

解决办法：

1、 yum install ncurses-devel ncurses

（python3.6的Modules源码里面有_curses相关的源码，但Setup里面注释掉了，取消注释编译会报错，后采取yum安装的方式解决了该报错）

2、清理了之前的安装目录/usr/local/python3，重新安装

./configure --prefix=/usr/local/python3

make && make install

重新执行bpthon，报错：

ModuleNotFoundError: No module named 'encodings'

whereis bpython 找到bpython所在位置，修改第一行解释器为/usr/local/python3/bin/python3.6

（这里其实可以把bpython指向的解释器改掉，建一个软连接，参考后文）

重新执行bpython，报错如下：

ModuleNotFoundError: No module named 'bpython'

问题解决：

[root@huwy22 usr]# pip3 uninstall bpython

Could not find platform independent libraries <prefix>

Could not find platform dependent libraries <exec_prefix>

Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]

Fatal Python error: Py_Initialize: Unable to get the locale encoding

ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f5d2a8fe7c0 (most recent call first):

[root@huwy22 usr]# whereis pip3

pip3: /usr/local/bin/pip3.6 /usr/local/bin/pip3

[root@huwy22 usr]# vi /usr/local/bin/pip3

（这里我还去改了pip3的解释器，后来怕其他地方也用到/usr/local/bin/python3.6，所以直接把这个文件做了调整，如下）

[root@huwy22 usr]# cd /usr/local/bin/

[root@huwy22 bin]# mv python3.6 python3.6.bak

[root@huwy22 bin]# ln -s /usr/local/python3/bin/python3.6 python3.6

[root@huwy22 bin]# pip3 uninstall bpython

Cannot uninstall requirement bpython, not installed

[root@huwy22 bin]# pip3 install bpython
