在 Ubuntu 16.04 中从任意目录运行程序

我在电脑上安装了天文学软件 CASA，我想只需casa在 Ubuntu 终端中输入即可从任何目录运行它。我应该进行哪些更改才能实现这一点？我尝试了以下方法：

sudo ln -s ./home/alcrespe/Desktop/casa-prerelease-4.7.0-22/bin/casa ./usr/bin/casa

...但它不起作用。我不是 Ubuntu 专家，我该如何解决这个问题？正如上一行所示，到目前为止，我只能在以下位置访问程序 CASA：

./home/alcrespe/Desktop/casa-prerelease-4.7.0-22/bin/casa

根据我的发现，您需要解决两个问题：

  1. 正确做法：

    • 尽管链接上说的是，但您显然没有steps correctly像我一样遵循并已使用命令成功运行它。casacasapy

    • 解决方法请按照步骤操作逐字。

      • sudo mkdir /usr/local/bin/CASA
      • sudo mv casapy-30.0.9860-001-64b.tar.gz /usr/local/bin/CASA
      • cd /usr/local/bin/CASA
      • sudo tar zxvf casapy-30.0.9860-001-64b.tar.gz
      • 将其添加到您的~/.bashrc文件中，然后使用以下命令获取它source ~/.bashrc：
        • export PATH=$PATH:/usr/local/bin/CASA/casapy-30.0.9860-001-64b/bin
      • 测试一下：casa

      • 输出：

         george@george-ubuntu-server:~$ casa

  2. 库问题。最新版本适用于 Ubuntu Xenial，而你安装的版本可能不适用于你的 Ubuntu 版本，正如我在尝试安装你的版本时发现的那样4.*。因此，请与您的导师联系以获取进一步的帮助。

重要的提示：

您可能希望将其安装在虚拟设备上，因为我注意到您的版本坚持创建一个具有 id 的用户，1001而不管该 id 的所有者是谁。在我的例子中，该用户koko被设为目录的组所有者/usr/local/bin/CASA/*。授予文件夹的权限：

drwxr-xr-x 11  12998   1001      4096 Jan  5 06:09 casa-stable-5.0.101/

更改casapy-30.0.9860-001-64b为您下载的或解压后显示的名称
