Bash 在 Lubuntu 18.04 上无法正常运行

当我运行该命令sudo bash或bash --version出现以下错误时：

bash: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version 'Qt_5.10' not found (required by bash)

的输出ldd如下：

的输出which bash为：

/usr/bin/bash

之前我尝试重新安装 ruby​​，因为软件包需要 2.2.8 版本，而我的 ruby​​ 2.5.RVM 无法正常工作，所以当我重新安装 ruby​​ 时，这些错误开始出现。

删除所有 PPA 和/或第三方软件包，然后重试。这不是标准的 Ubuntu 软件包。

常规 bash 命令位于 中/bin/bash。如果使用完整路径调用它，则应该能够运行它。所讨论的包/usr/bin/bash是您安装的（可能是错误安装的），并且它优先于命令which，因为/usr/bin出现在$PATH之前/bin。

您可以通过更改 PATH 变量以使其在/bin之前列出来规避此问题/usr/bin。
