Jhipster 应用程序：使用 Maven 打包时 Bower 出现问题

Question

我正在开发 Jhipster 应用程序 (v3.0.0)。我知道这是一个旧版本，但也许有人遇到过这个问题。
我已经尝试使用
安装凉亭 - 纱线
- npm（使用 sudo 否则我无法安装它，我遇到了 EACCESS 问题）

当我打包我的 webapp 时，我收到了这个错误：

[INFO] --------------------------------------
[INFO]          BOWER INSTALL --NO-COLOR
[INFO] --------------------------------------
bower ESUDO         Cannot be run with sudo

Additional error details:
Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs.

You can however run a command with sudo using --allow-root option

我不知道怎么解决。
如果有人有想法...

谢谢

要运行 bower 作为root 用户，您需要在.bowerrc 中添加allow_root 键（位于项目的根目录）

{
    "directory": "src/main/webapp/bower_components",
    "allow_root": true
}

附带说明一下，在使用 NPM 安装软件包时不应使用 sudo。请参阅 "How to Prevent Permissions Errors"

上的 NPM 文档
