这个错误通常表示你在 Windows 命令提示符中输入了无效的命令或语法。
首先,你可以尝试在命令之前添加 "cmd /c" 前缀,例如:
```
cmd /c .
```
如果这个命令可以执行,那么很可能是你的环境变量配置不正确。你可以检查 PATH 环境变量是否包含了系统命令的目录,例如 C:\Windows\System32。
如果仍然无法解决问题,你可以尝试更新你的 Windows 系统或者重新安装操作系统。

javac' is not recognized as an internal or external command, operable progr
这个错误通常是因为Java编译器没有正确地添加到系统路径中。要解决这个问题,你需要按照以下步骤操作:
1. 首先,确认你已经正确地安装了Java开发工具包(JDK)。你可以在命令行输入"java -version"来确认JDK是否已经正确地安装和配置。
2. 然后,打开控制面板,点击"系统与安全",再点击"系统",找到"高级系统设置",点击"环境变量"。
3. 在环境变量中,找到"系统变量"中的"Path"变量,点击编辑。
4. 在编辑系统变量窗口中,点击"新建",添加JDK的安装路径,通常是"C:\Program Files\Java\jdk_version\bin"。然后点击"确定"保存设置。
5. 最后,重新打开命令提示符窗口,输入"javac"命令,如果不再出现错误信息,则表示已经成功地解决了这个问题。
只需要按照这些步骤正确地配置JDK的安装路径到系统的环境变量中,就可以解决"javac is not recognized as an internal or external command, operable program"的错误。希望对你有所帮助。
'allure' is not recognized as an internal or external command,
This error message usually occurs when the 'allure' command is not recognized by the command prompt or terminal. It may indicate that the Allure command-line interface (CLI) is not installed or not added to the system PATH environment variable.
To resolve this issue, you can try the following steps:
1. Install Allure CLI by running the following command in the command prompt or terminal:
```
npm install -g allure-commandline
```
2. Add the Allure CLI path to the system PATH environment variable. You can do this by following these steps:
- Open the Start menu and search for "Environment Variables".
- Click on "Edit the system environment variables".
- Click on the "Environment Variables" button.
- Under "System Variables", scroll down and find the "Path" variable, then click "Edit".
- Click "New" and add the path to the allure command-line interface (e.g. "C:\Users\{username}\AppData\Roaming\npm").
- Click "OK" to save the changes.
After completing these steps, try running the 'allure' command again in the command prompt or terminal. It should be recognized now.
