Answer 1

我将pom更改为使用不同的节点版本。

<nodeVersion>v9.11.1</nodeVersion>

然后我运行了mvn clean install。这失败了，但它通过了安装部分，并在运行构建时失败。然后我切换回<nodeVersion>v12.14.1</nodeVersion>并重新运行mvn clean install，它工作了。

Answer 2

我升级了Node LTS版本，现在它可以工作了。

Answer 3

这是节点版本问题。也可能是您的全局节点版本不匹配。

我已经用node版本10.16.0实现了以下代码

<plugin>
            <groupId>com.github.eirslett</groupId>
            <artifactId>frontend-maven-plugin</artifactId>
            <version>1.7.6</version>
            <configuration>
                <nodeVersion>v10.16.0</nodeVersion>
                <npmVersion>6.10.2</npmVersion>
                <workingDirectory>./angular</workingDirectory>
            </configuration>
            <executions>
            
                <execution>
                    <id>install node and npm</id>
                    <goals>
                        <goal>install-node-and-npm</goal>
                    </goals>
                    <phase>generate-resources</phase>
                </execution>
        
        
                <execution>
                        <id>npm install</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <phase>generate-resources</phase>
                        <configuration>
                            <arguments>install</arguments>
                        </configuration>
                </execution> 
        
    
                <execution>
                    <id>npm run-script build</id>
                    <goals>
                        <goal>npm</goal>
                    </goals>
                    <phase>generate-resources</phase>
                    <configuration>
                        <arguments>run-script build</arguments>
                    </configuration>
                </execution>
            </executions>
        </plugin>

如果仍然不起作用，请尝试使用force属性清除npm缓存

npm cache clean --force
