海马不会跑，如何正确移除旧版本？

Question

如果单击密码和密钥别名seahorse，则不会运行。

当从终端启动时，我会得到以下错误：

seahorse: error while loading shared libraries: libldap_r-2.4.so.2: cannot open shared object file: No such file or directory

当我试图找到这样的软件包并可能安装它时，我得到：

$ which seahorse 
/usr/local/bin/seahorse
$ whereis seahorse
seahorse: /usr/bin/seahorse /usr/local/bin/seahorse /usr/libexec/seahorse /usr/share/seahorse /usr/share/man/man1/seahorse.1.gz

因此，我自然地尝试了/usr/bin/seahorse，并启动并运行了它：

因此，我挖掘了下载目录，发现：

/home/vlastimil/Downloads/seahorse/seahorse-3.31.91

带有时间戳的2019年2月23日。由meson构建，但是如何删除它呢？

Answer 1

如果您仍然拥有完整的构建树，可能在/home/vlastimil/Downloads/seahorse/seahorse-3.31.91/build中，那么

cd /home/vlastimil/Downloads/seahorse/seahorse-3.31.91/build
sudo ninja uninstall

或

cd /home/vlastimil/Downloads/seahorse/seahorse-3.31.91/build
sudo make uninstall

应该卸载Seahorse的/usr/local版本。

如果生成树不可用，则必须重新执行构建步骤，最好使用2019年使用的相同参数：

cd /home/vlastimil/Downloads/seahorse/seahorse-3.31.91
meson build
cd build && sudo ninja uninstall
