如何安装共享库

Question

我对思科PacketTracer有个问题

https://www.netacad.com/courses/packet-tracer

wolf@linux:/opt/pt/bin$ ./PacketTracer7
./PacketTracer7: error while loading shared libraries: libQt5WebEngineWidgets.so.5: cannot open shared object file: No such file or directory
wolf@linux:/opt/pt/bin$

事实证明，有些图书馆并不存在：

wolf@linux:/opt/pt/bin$ ldd PacketTracer7 | grep not
    libQt5WebEngineWidgets.so.5 => not found
    libQt5WebEngineCore.so.5 => not found
    libQt5Script.so.5 => not found
    libQt5ScriptTools.so.5 => not found
wolf@linux:/opt/pt/bin$

我试过安装它，但没有用：

wolf@linux:/opt/pt/bin$ sudo apt install libQt5WebEngineWidgets.so.5 libQt5WebEngineCore.so.5 libQt5Script.so.5 libQt5ScriptTools.so.5
Reading package lists... Done
Building dependency tree

E: Unable to locate package libQt5WebEngineWidgets.so.5
E: Unable to locate package libQt5WebEngineCore.so.5
E: Unable to locate package libQt5Script.so.5
E: Unable to locate package libQt5ScriptTools.so.5
wolf@linux:/opt/pt/bin$

我还尝试将其更改为小写，并将.so.5从名称中删除，但仍然无法工作。

sudo apt install libQt5WebEngineWidgets.so libQt5WebEngineCore.so libQt5Script.so libQt5ScriptTools.so

sudo apt install libQt5WebEngineWidgets libQt5WebEngineCore libQt5Script libQt5ScriptTools

sudo apt install libqt5webenginewidgets libqt5webenginecore libqt5script libqt5scripttools

怎样才是正确的方法？

<#>更新

这将安装前两个库，它们是libQt5WebEngineWidgets.so.5和libQt5WebEngineCore.so.5，但不是最后两个库：

sudo apt install libqt5webenginewidgets5 libqt5webenginecore5

还需要安装两个库：

wolf@linux:/opt/pt/bin$ ldd ./PacketTracer7 | g not
    libQt5Script.so.5 => not found
    libQt5ScriptTools.so.5 => not found
wolf@linux:/opt/pt/bin$

Answer 1

图书馆的名称必须是正确的；它也区分大小写。试试这个：

sudo apt install libqt5webenginewidgets5 libqt5webenginecore5 libqt5script5 libqt5scripttools5

另外，使用提供的shell脚本。不要直接运行ELF文件。那不管用。

/opt/pt/packettracer

Answer 2

试试这个：

sudo apt install libqt5webenginecore5 libqt5webenginewidgets5 libqt5script5 libqt5scripttools5

它会把更多的包裹拖过去。

我使用apt-cache找到了这些，例如，下面是前两个

~$ apt-cache search libQt5Script
libqt5script5 - Qt 5 script module
libqt5scripttools5 - Qt 5 script tools module

...and后两位

~$ apt-cache search libQt5Script
libqt5script5 - Qt 5 script module
libqt5scripttools5 - Qt 5 script tools module

您还可以组合两个搜索单词。

apt-cache search 'libQt5WebEngine|libQt5Script'

最后，在https://packages.ubuntu.com/有一个可搜索的包数据库。
