无法运行程序ng

Question

我正在使用Angular 5开发Spring Boot应用程序。

我的 npm ，节点和 angular / cli 安装正确

1. npm -v：6.4.1
2. 节点-v：v8.9.1
3. ng -v：6.2.3

pom.xml 文件中出现 ng命令的部分：

                    <execution>
                        <id>npm-install-build</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                        <configuration>
                            <executable>ng</executable>
                            <arguments>
                                <argument>build</argument>
                            </arguments>
                        </configuration>
                    </execution>

当我尝试使用mvn -U clean install编译我的项目时，出现此错误：

[ERROR] Command execution failed. java.io.IOException: Cannot run program "ng" (in directory "C:\Users\AN5810BN\intellj-workspace\stmms-cdc-async\stmms-cdc-async-service\src\main\ui"): CreateProcess error=2, Le fichier sp▒cifi▒ est introuvable

我该如何解决这个问题？

Answer 1

local ng命令对我有用，要运行此命令，我们使用 $ npm run ng build

所以我将问题中pom.xml的部分替换为：

 <execution>
                        <id>npm-ng-build</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                        <configuration>
                            <executable>npm</executable>
                            <arguments>
                                <argument>run</argument>
                                <argument>ng</argument>
                                <argument>build</argument>
                            </arguments>
                        </configuration>
                    </execution>

效果很好
