Dart pub 工具的返回码是什么

Question

我将在批处理文件中反复启动“pub get”和“pub build”，我需要测试返回码是否有错误。Dart 文档中似乎没有记录返回代码。有谁知道他们是什么，或者他们在哪里记录？

我发现了这些：

• 在pub.dart 中搜索“exit_codes”以查看使用了哪些常量
• 常量值在此处定义：（从exit_codes.dart复制）

library pub.exit_codes;

/// The command completely successfully.
const SUCCESS = 0;

/// The command was used incorrectly.
const USAGE = 64;

/// The input data was incorrect.
const DATA = 65;

/// An input file did not exist or was unreadable.
const NO_INPUT = 66;

/// The user specified did not exist.
const NO_USER = 67;

/// The host specified did not exist.
const NO_HOST = 68;

/// A service is unavailable.
const UNAVAILABLE = 69;

/// An internal software error has been detected.
const SOFTWARE = 70;

/// An operating system error has been detected.
const OS = 71;

/// Some system file did not exist or was unreadable.
const OS_FILE = 72;

/// A user-specified output file cannot be created.
const CANT_CREATE = 73;

/// An error occurred while doing I/O on some file.
const IO = 74;

/// Temporary failure, indicating something that is not really an error.
const TEMP_FAIL = 75;

/// The remote system returned something invalid during a protocol exchange.
const PROTOCOL = 76;

/// The user did not have sufficient permissions.
const NO_PERM = 77;

/// Something was unconfigured or mis-configured.
const CONFIG = 78;
