不能 运行 多个项目与离子服务
Cant run multiple projects with ionic serve
我正在使用 ionic2。以下是 ionic info 产生的所有信息。我主要从事两个不同的离子项目，我想同时为他们提供服务。执行 ionic serve 时默认在端口 8000 上加载一个项目。我尝试使用 ionic serve --port 8101 更改第二个端口。但这并没有启动第二个项目。
这是以下错误：

编辑 (11/16/2016)：所以 运行 第二个项目 ionic serve --port 3000 --dev-log-server 8101 成功了。不过，我仍然在终端中遇到错误，仅供参考。
错误是
Error: listen EADDRINUSE 0.0.0.0:53703
所以在某些时候 ionic 正在尝试使用不可用的端口 53703。
$ grep -rns 53703 *
node_modules/@ionic/app-scripts/dist/dev-server/dev-server.js:104:var DEV_LOGGER_DEFAULT_PORT = 53703;
当我 运行 你有两个 ionic 实例时，我的系统中没有任何东西使用端口 53703。
据说我是 运行ning ionic-app-scripts 0.0.39，这是 rc2 教程附带的版本。
几个选项：
- 尝试传递另一个开发记录器端口（通过
--dev-logger-port）
- 使用
lsof 找出占用端口 53703 的进程并终止该进程 (lsof | grep 53703)
- 尝试将
ionic-app-scripts 降级为 0.0.39
我遇到了同样的问题。
稍加挖掘后发现 livereload-port 使用 35729 端口，dev-logger-port 使用 35703 端口。
运行 解决了问题：
离子服务 --port 8081 --livereload-port 35730 --dev-logger-port 53704
