廣東話運行離子在多個項目中擔任

林與ionic2工作。以下是ionic info生成的所有信息。我基本上在兩個不同的離子項目上工作，我想同時爲他們提供兩個項目。在執行ionic serve時，默認情況下，一個項目在端口8000上加載。我試圖通過使用ionic serve --port 8101來更改第二個端口。但是這並不能啓動第二個項目。廣東話運行離子在多個項目中擔任

這是以下錯誤：

編輯（2016年11月16日）：因此，與ionic serve --port 3000 --dev-log-server 8101運行第二個項目的工作。儘管如此，我仍然在終端出現錯誤，只是fyi。

的錯誤是

Error: listen EADDRINUSE 0.0.0.0:53703

所以在某些時候離子試圖使用端口53703，這是不可用的。

$ grep -rns 53703 * 
node_modules/@ionic/app-scripts/dist/dev-server/dev-server.js:104:var DEV_LOGGER_DEFAULT_PORT = 53703;

當我運行的離子兩個實例，你有，沒有在我的系統使用端口53703.

話雖這麼說，我跑離子-APP-腳本0.0.39，這是版本附帶rc2教程。

幾個選項：

嘗試通過另一種開發記錄器端口（通過--dev-logger-port）
使用lsof找出什麼是保持口53703，殺死該進程（lsof | grep 53703）
嘗試降級ionic-app-scripts到0.0.39

我面臨同樣的問題。

後發現了一個小挖的是35729端口被livereload端口和35703端口dev所記錄器端口。

運行問題解決了：離子服務--port 8081 --livereload端口35730 --dev記錄器端口53704
