我正在运行全新安装的 Ubuntu 18.04.3。所以我的问题是：当我以通常的方式使用终端安装 texstudio 时，一切似乎都运行顺利：
zosiah@zosiah-HP-255-G6-Notebook-PC:~$ sudo apt install texstudio

但是当我尝试运行 texstudio 终端时说：
zosiah@zosiah-HP-255-G6-Notebook-PC:~$ texstudio
texstudio: error while loading shared libraries: libdouble-conversion.so.1: cannot open shared object file: No such file or directory
我在谷歌上搜索了一段时间，但还是没有找到解决方案……有什么想法吗？PS 我也无法安装 texmaker 和 emacs25。这对我来说听起来很奇怪，因为到目前为止，我从未遇到过这样的问题，无论是使用 synaptic 还是使用 apt 等等……到底是怎么回事？

编辑 3：使用以下终端命令重新安装库后问题解决：
sudo apt install --reinstall libxcb-xinerama0
答案1
问题解决了，只需使用以下终端命令重新安装库 libxcb-xinerama0 即可：
sudo apt install --reinstall libxcb-xinerama0
答案2
sudo apt install --reinstall libdouble-conversion1
我在运行 texstudio 时遇到了相同的初始错误。但是，ldd $(which texstudio | grep not)报告了libdouble-conversion.so.1 => not found。
解决方案是重新安装库，按照此建议用户“Manfred”在此处发布关于 LaunchPad 的线程。
