subprocess.CalledProcessError: Command 'git tag' returned non-zero exit status 127.

当你在使用subprocess模块执行命令时，如果命令返回非零退出状态码，就会引发subprocess.CalledProcessError异常。这通常表示命令执行失败。在你提供的引用中，命令'git tag'返回了非零退出状态码127[^1]。
要处理这个异常，你可以使用try-except语句来捕获并处理异常。在except块中，你可以根据需要执行适当的操作，例如打印错误消息或采取其他恢复措施。
下面是一个示例代码，演示了如何处理subprocess.CalledProcessError异常：
import subprocess

try:
subprocess.run(['git', 'tag'], check=True)
except subprocess.CalledProcessError as e:
print(f"Command 'git tag' returned non-zero exit status {e.returncode}.")
# 在这里可以添加其他处理代码

在这个示例中，我们使用subprocess.run函数执行了'git tag'命令，并设置了check=True参数，这样当命令返回非零退出状态码时，就会引发subprocess.CalledProcessError异常。在except块中，我们打印了错误消息，并可以添加其他处理代码来处理异常情况。

Ensure that the user running the command has the necessary permissions to execute Git commands.

这个错误通常是由于在执行 "git tag" 命令时出现了问题，可能是由于没有权限或者在错误的目录下执行了该命令。您可以尝试检查当前的工作目录是否正确，并确保您拥有执行该命令的权限。另外，您可以尝试使用 "git status" 命令检查当前的 Git 状态，以确保您在正确的分支上工作。如果这些方法都无法解决问题，您可以尝试搜索相关的错误信息，或者提供更多的上下文信息以便更好地帮助您解决问题。
