我正在尝试创建如下所示的打包程序版本，但权限被拒绝。由于我在尝试执行 shell 脚本时也遇到了同样的问题，因此我认为根本原因可能是操作系统层配置错误（见下文）。这里的问题是，使用 shell 脚本时，我有一个运行“bash scriptname.sh”的变通方法，而使用打包程序时我没有这个选项。

然而，目录权限对我来说看起来很好：

如果我将构建语句替换为以下内容，我会得到同样的错误：
PACKER_LOG=1 packer plugins install github.com/hashicorp/vsphere
话虽如此，我感觉它与以下内容有关，即我无法运行./executable。
[userid@host vsphere]$ vi test.sh
[userid@host vsphere]$ chmod 0755 test.sh
[userid@host vsphere]$ ./test.sh
-bash: ./test.sh: Permission denied
[userid@host vsphere]$ bash test.sh
This is a test
[userid@host vsphere]$ cat test.sh
#!/bin/bash
echo "This is a test"
同样，执行插件可执行文件也不起作用：
[userid@host vsphere]$ . ./packer-plugin-vsphere_v1.2.7_x5.0_linux_amd64
-bash: .: ./packer-plugin-vsphere_v1.2.7_x5.0_linux_amd64: cannot execute binary file
[user@host vsphere]$ ./packer-plugin-vsphere_v1.2.7_x5.0_linux_amd64
-bash: ./packer-plugin-vsphere_v1.2.7_x5.0_linux_amd64: Permission denied
[user@host vsphere]$ export PATH=${PATH}:.
[user@host vsphere]$ packer-plugin-vsphere_v1.2.7_x5.0_linux_amd64
-bash: ./packer-plugin-vsphere_v1.2.7_x5.0_linux_amd64: Permission denied
我不认为这与 SELinux 相关，因为下面的输出对我来说看起来不错。
[user@host vsphere]$ ls -latZ .

通过运行 setenforce=0 并重新运行上述操作，我进一步确认这与 SELinux 无关。
关于如何让打包插件正常工作，您有什么想法吗？
