python报错Could not open PYTHONSTARTUP

Could not open PYTHONSTARTUP
IOError: [Errno 2] No such file or directory: '/root/.pystartup'

解决方案：

1.创建文件并添加内容

vi /root/.pystartup

import sys

import readline

import rlcompleter

import atexit

import os

readline.parse_and_bind('tab: complete')

histfile =   os.path.join(os.environ['HOME'], '.pythonhistory')

try:

      readline.read_history_file(histfile)

except IOError:

      pass

atexit.register(readline.write_history_file, histfile)

del os, histfile, readline, rlcompleter

 

2.执行如下命令：

echo "export PYTHONSTARTUP=~/.pystartup" >> ~/.bashrc
source /root/.bashrc

再次进入python编辑器就不报错了！
