它是如此的有線，我不能跑「NPM -v」當我在的IntelliJ無法使用公地EXEC運行命令行中使用Java時觸發搖籃測試
public class Main {
public static void main(String[] args) throws IOException, InterruptedException {
DefaultExecutor executor = new DefaultExecutor();
executor.execute(CommandLine.parse("npm -v"));
}
}
public class MainTest {
@Test
public void name() throws Exception {
Main.main(new String[]{});
}
}
運行測試用例的搖籃插件一切工作正常，當我：用罐子
1.啓動應用
2.使用的IntelliJ觸發測試用例（右鍵點擊並運行「MainTest」）
3.運行gradle clean check
但是當我運行使用搖籃插件測試，永遠變得不安。

嘗試打印'PATH'環境從你的代碼中剔除變量，並且在它的工作和不工作時比較結果。 PATH是否一樣？它是否包含'npm'二進制文件的路徑？ – CrazyCoder
