Testing 如何修复量角器、log4js配置错误？

我正在尝试运行量角器测试。但面对log4js的问题。我没有npm安装log4js。启动前配置看起来正确吗？当前版本的log4js的格式有什么需要更改的吗

以下是错误：

Error: Problem with log4js configuration: ({
  appenders: {
    out: {
      type: 'log4js-protractor-appender',
      category: 'protractorLog4js'
    },
    app: {
      type: 'file',
      filename: './logs/ExecutionLog.log',
      category: 'protractorLog4js'
    }
  },
  categories: { default: { appenders: [ 'out', 'app' ], level: 'info' } }
}) - appender "out" is not valid (type "log4js-protractor-appender" could not be found)

谢谢

log4js支持的附件类型有：

export type Appender = CategoryFilterAppender
    | ConsoleAppender
    | FileAppender
    | SyncfileAppender
    | DateFileAppender
  | LogLevelFilterAppender
  | NoLogFilterAppender
    | MultiFileAppender
    | MultiprocessAppender
    | RecordingAppender
    | StandardErrorAppender
    | StandardOutputAppender
    | CustomAppender;

如果从名称中删除“appender”，您将获得支持的类型，例如：控制台、文件、多文件。。。等

下面是一个配置示例

const log4js_config: Configuration = {
        appenders: {
            consoleErrors: {
                type: 'logLevelFilter',
                appender: 'console',
                level: 'error'
            },
            console: {
                type: 'console'
            },
        },
        categories: {
            default: { appenders: [ 'console', 'consoleErrors' ], level: 'debug' }
        }
    };

const Log4js = require('log4js');
log4js.configure(LOG4JS_CONFIGURATION);

像这样，默认类别中有两种类型的追加器

• console appender将记录控制台中的所有内容，无论级别如何
• consoleErrors覆盖console的其他规则，并仅过滤console的错误级别或更高级别的消息

附录程序的工作方式和配置示例：

const log4js_config: Configuration = {
        appenders: {
            consoleErrors: {
                type: 'logLevelFilter',
                appender: 'console',
                level: 'error'
            },
            console: {
                type: 'console'
            },
        },
        categories: {
            default: { appenders: [ 'console', 'consoleErrors' ], level: 'debug' }
        }
    };

const Log4js = require('log4js');
log4js.configure(LOG4JS_CONFIGURATION);
