【问题描述】：

我正在我的 maven webapp 上试用 yeoman-maven-plugin。当我运行“clean install -DskipTests=true -X”时，我得到以下输出。不确定发生了什么，因为“yo”目录确实存在于我的项目的根目录中。我在该目录中运行“yo angular --minsafe”来初始化应用程序。

【问题讨论】：

所以我确定它在控制台上可以正常工作，但是在 IntelliJ 中运行时失败了......
帕特里克找到解决方案了吗？

【解决方案1】：

感谢您对 yeoman-maven-plugin 的关注。

我认为问题在于 npm 不在 IntelliJ 等 GUI 应用程序的 PATH 上。解决方案是创建/编辑 /etc/launchd.conf 文件并添加 npm 路径（我用 brew 安装了 npm，然后我为 npm 路径和 /usr/local 添加了 /usr/local/bin /share/npm/bin 用于包 (yo, grunt, ...)

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