如何安裝ogre-meshviewer？

Question

我正在嘗試安裝ogre-meshviewer，但出現以下錯誤：

(base) comp@comp:~$ sudo snap install ogre-meshviewer
snap "ogre-meshviewer" is already installed, see 'snap help
              refresh'
(base) comp@comp:~$ 
(base) comp@comp:~$ sudo ogre-meshviewer
mkdir: cannot create directory '/run/user/0': Permission denied
realpath: '': No such file or directory
realpath: '': No such file or directory
realpath: '': No such file or directory
realpath: '': No such file or directory

realpath: '': No such file or directory
realpath: '': No such file or directory
usage: ogre_mesh_viewer.py [-h] [-c RESCFG] infile
ogre_mesh_viewer.py: error: the following arguments are required: infile

我該如何解決這個問題？

Answer 1

正如命令的輸出sudo snap install ogre-meshviewer通知您，ogre-meshviewer已成功安裝。

您收到的錯誤是因為您嘗試ogre-meshviewer在沒有所需位置參數（infile輸入檔案）的情況下執行：

usage: ogre_mesh_viewer.py [-h] [-c RESCFG] infile
ogre_mesh_viewer.py: error: the following arguments are required: infile

因此，如果您將其運行為：

ogre-meshviewer /path/to/mesh_file

它應該可以正常工作。

/path/to/mesh_file正如預期的那樣，是文件的路徑.mesh（或任何其他支援的格式，即.obj，.ply或.fbx) 已存在於您的系統中。路徑可以是絕對或相對。
