我将首次使用 Vagrant。我使用的是 M1 Mac。

我的vagrant up命令失败并显示以下消息：

vagrant up

Bringing machine 'mysql3' up with 'virtualbox' provider...

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "37d985a0-dc89-4d49-a7f9-02af2ca9b5a4", "--type", "headless"]

Stderr: VBoxManage: error: The VM session was aborted
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component SessionMachine, interface ISession

我在 macOS 上使用它。我还安装了 Virtual Box。

作为故障排除目的的一部分，我尝试重新安装 vagrant hostmanager，但是我还收到以下消息：

vagrant plugin install vagrant-hostmanager

Installing the 'vagrant-hostmanager' plugin. This can take a few minutes...
Vagrant failed to properly resolve required dependencies. These
errors can commonly be caused by misconfigured plugin installations
or transient network issues. The reported error is:

conflicting dependencies logger (= 1.6.0) and logger (= 1.6.1)
  Activated logger-1.6.1
  which does not match conflicting dependency (= 1.6.0)

  Conflicting dependency chains:
    logger (= 1.6.1), 1.6.1 activated

  versus:
    logger (= 1.6.0)

  Gems matching logger (= 1.6.0):
    logger-1.6.0

对于大多数人来说，这可能是一个简单的问题。但是，我只是 shell 脚本的新手，在某个地方我看到了这个：

#!/bin/sh
X=0
while [ -n "$X" ]
do
  echo "Enter some text (RETURN to quit)"
  read X
  echo "You said: $X"
done

我不明白这里的 -n 是什么。我用谷歌搜索，但找不到任何关于 -n 的信息。任何建议将不胜感激。
