Question

我正在通过以下命令创建ionic v2项目：

sudo ionic start demoApp blank --V2

但是鉴于以下cmd错误，我正在使用iMac。

  npm WARN deprecated browserslist@2.11.3: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools.

> fsevents@1.2.4 install /demoApp/node_modules/fsevents

        Re-running this command with the --verbose flag may provide more information.

我已经授予权限并运行以下命令：

sudo npm install -g --unsafe-perm node-sass

 sudo npm install -g node-sass

请建议我如何解决此类错误和权限。

Answer 1

登录的用户可能不是NPM目录的所有者。参见this。

Answer 2

我已经将ionic CLI升级到了最新版本，并且对ionic2项目也遇到了同样的问题。将npm的默认目录更改为全局目录，即可解决所有问题。
