rlwrap：无法打开master pty：没有这样的文件或目录 [英] rlwrap: Could not open master pty: No such file or directory

问题描述

尝试运行 rlwrap tclsh 时收到此错误消息：

  rlwrap：无法打开master pty：没有这样的文件或目录
  

如何解决此问题？

我运行64位CentOS。

解决方案

检查/ dev / ptmx
have
crw-rw-rw -
我曾经有过
crw -------

请参阅 man ptmx ：

文件/ dev / ptmx是主要数字5和次要数字2的字符文件，通常为模式0666和root.root的owner.group。它用于创建伪终端主从副本。

When trying to run rlwrap tclsh I am getting this error message:

rlwrap: Could not open master pty: No such file or directory

What causes this? How to fix this issue?

P.S. I am running 64 bit CentOS.

解决方案

check /dev/ptmx it should have crw-rw-rw- I once had it crw------- this caused the error message at my system.

see also man ptmx:

The file /dev/ptmx is a character file with major number 5 and minor number 2, usually of mode 0666 and owner.group of root.root. It is used to create a pseudo-terminal master and slave pair.
