打字稿错误：TS2345：类型'{主题：字符串； jsonFile：字符串；输出：字符串； }; }' 不可分配给类型为'Options'的参数

如何解决打字稿错误：TS2345：类型'{主题：字符串； jsonFile：字符串；输出：字符串； }; }' 不可分配给类型为'Options'的参数

我从以下代码中收到标题中的错误：

import * as fs from 'fs'
import { mkdirp } from 'mkdirp'
import * as report from 'cucumber-html-reporter'
const Cucumber = require('cucumber')

export class CucumberReportExtension {

    private static jsonDir = __dirname + '/../../test/reports/json';
    private static htmlDir = __dirname + '/../../test/reports/html';
    private static jsonFile = CucumberReportExtension.jsonDir + '/cucumber_report.json';

    private static cucumberReporterOptions = {
        theme: 'bootstrap',jsonFile: CucumberReportExtension.jsonFile,output: CucumberReportExtension.htmlDir + '/cucumber_reporter.html',reportSuiteAsScenarios: true,launchReport: true,Metadata: {
            'App Version':'1.0.0','Test Environment': 'Development',browser: 'Chrome  84.0.4147.105',Platform: 'Windows 10',Parallel: 'Scenarios',Executed: 'Local'
        }
    }

    public static CreateReportFile(dirName) {
        // Check of the directory exist
        if (!fs.existsSync(dirName))
            mkdirp.sync(dirName);
    }

    public static GenerateCucumberReport(){

        report.generate(CucumberReportExtension.cucumberReporterOptions);
    }

}

我的 package.json 包含：

    "@types/jasmine": "^3.5.11","@types/jasminewd2": "^2.0.8","@types/node": "^14.0.14","faker": "^5.1.0","jasmine": "^3.5.0","lodash": "^4.17.20","log4js": "^6.3.0","log4js-protractor-appender": "^1.1.2","mkdirp": "latest","moment": "^2.28.0","pg": "^8.3.3","pg-hstore": "^2.3.3","protractor": "^7.0.0","qs": "^6.9.4","stringinject": "^2.1.1"

  }
}

解决方法

通过查看传递给 <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>${maven-compiler.version}</version> <configuration> <source>1.8</source> <target>1.8</target> <fork>true</fork> <executable>/usr/lib/jvm/java-8-openjdk-amd64/bin/javac</executable> <compilerArgs> <arg>classpath=*:.</arg> <arg>-verbose</arg> <arg>-Xlint:all,-options,-path</arg> </compilerArgs> <excludes> <exclude>x/y/z/**</exclude> </excludes> </configuration> </plugin> 的 Options 对象的 expected type，我可以看到他们期望的 report.generate 类型是字符串文字的联合。

您的主题 theme 是这些选项之一，但在错误消息中，您可以看到打字稿将其解释为 'bootstrap' 而不是文字字符串 string。 您可以使用 'bootstrap' 以便打字稿将其视为文字：

as const
