使用yeoman-maven-plugin無法執行使用npm安裝錯誤生成錯誤

Question

我試着在我的maven webapp上使用yeoman-maven-plugin。當我運行「clean install -DskipTests = true -X」時，我得到以下輸出。不知道發生了什麼事情，因爲我的項目的根目錄中存在「喲」目錄。我在該目錄中運行「yo angular --minsafe」來初始化應用程序。

感謝您的自耕農，Maven的插件的興趣。

我認爲問題在於npm不在IntelliJ等GUI應用程序的PATH上。 解決方案是創建/編輯/ etc/launchd.conf文件並添加npm路徑（我在brew中安裝了npm，然後爲npm路徑和/ usr/local/share/npm添加了/ usr/local/bin/bin中的包（喲，咕嚕...）

setenv PATH /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/share/npm/bin
