./runtime2.sh: line 50: 4: command not found

这个错误提示表明在 `runtime2.sh` 脚本的第50行中，Shell 解释器将 `4` 当作一个命令来执行，但是却找不到对应的命令。出现这种错误的原因通常是语法错误或者变量名错误，导致 Shell 解释器将 `4` 当作命令来执行。你可以检查一下脚本的语法以及变量名是否正确。此外，你也可以提供更多的上下文信息，以便更准确地找出问题所在。

This error message means that the Java runtime environment (JRE) is not installed on your system or it is not configured properly. To resolve this issue, you need to install Java on your system and set up the environment variables correctly.

Here are the steps to install Java on Ubuntu:

1. Open the terminal by pressing Ctrl+Alt+T.
2. Update the package list by running the following command:

sudo apt-get update

3. Install Java by running the following command:

sudo apt-get install default-jre

4. Verify the installation by running the following command:

java -version

This command will display the version of Java installed on your system.

If you still face the issue, you may need to set up the environment variables. Here are the steps to set up the environment variables:

1. Open the terminal by pressing Ctrl+Alt+T.
2. Edit the environment variables file by running the following command:

sudo nano /etc/environment

3. Add the following line at the end of the file:

JAVA_HOME="/usr/lib/jvm/default-java"

4. Save and close the file by pressing Ctrl+X, then Y, and finally Enter.
5. Reload the environment variables by running the following command:

source /etc/environment

Now, try running the start.sh script again. It should work without any errors.

看起来你在运行QCPE配置验证时遇到了一个错误。错误信息显示找不到dotnet可执行文件。这通常意味着你需要安装.NET Core Runtime并将其添加到系统的路径中。

请确保你已正确安装了.NET Core Runtime，并将其添加到环境变量中。你可以使用以下命令检查是否安装了.NET Core Runtime：

dotnet --version

如果返回版本号，则说明已正确安装。否则，请按照以下步骤安装：

1. 访问 [Microsoft官方网站](https://dotnet.microsoft.com/download/dotnet) ，下载并安装.NET Core Runtime。
2. 安装完成后，打开终端并重新启动您的操作系统，以便更新环境变量。
3. 再次运行QCPE配置验证命令，应该可以成功执行。
