Node.js error in Vaadin Spring Boot application
问题
尝试在Intellij IDEA中运行包含以下build.gradle的使用Vaadin创建CRUD UI项目：
plugins {
id 'org.springframework.boot' version '2.3.2.RELEASE'
id 'io.spring.dependency-management' version '1.0.8.RELEASE'
id 'java'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
maven { url "https://maven.vaadin.com/vaadin-addons" }
}
dependencyManagement {
imports {
mavenBom 'com.vaadin:vaadin-bom:14.3.9'
}
}
dependencies {
implementation 'com.vaadin:vaadin-spring-boot-starter'
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
runtimeOnly 'com.h2database:h2'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
}
test {
useJUnitPlatform()
}
在运行项目时遇到了节点问题：
2020-10-07 19:01:42.637 INFO 8364 --- [ main] NodeInstaller : Installing node version v12.18.3
...
C:\Users\g\.vaadin\node\node.exe: bad option: --no-update-notifier
...
java.lang.RuntimeException: Unable to initialize Vaadin DevModeHandler
如何解决这个问题？

Node.js的版本是vaadin附带的问题。安装最新版本的Node.js。转到其安装目录，复制node_modules文件夹和node.exe文件，然后将它们替换到C:\Users~.vaadin\node中。
英文:
