Question

我在将项目运行到android模拟器时遇到问题：当我运行此命令“ ionic cordova emulator android”时，它将出错。我正在使用动态ssh和socks隧道运行腻子。我的终端的完整日志如下所示。

PS D:\Hamid\wooionic2> ionic cordova run android

Without `from` option PostCSS could generate wrong source map and will not find Browserslist config. Set it to CSS file path or to `undefined`

[OK] Your app has been deployed.
     Did you know you can live-reload changes from your app with --livereload?

它说：

错误在哪里？

Answer 1

我禁用了腻子（充当代理），然后再次运行命令：“ cordova仿真android”

但是这次感觉到了新的错误：

A problem occurred configuring root project 'android'.

无法解析配置'：classpath'的所有文件。无法解析com.android.tools.build:gradle:3.0.0。要求：项目：无法解析com.android.tools.build:gradle:3.0.0。无法获取资源“ https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.0/gradle-3.0.0.pom”。无法获取'https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.0/gradle-3.0.0.pom'。连接到 127.0.0.1:8085 [/127.0.0.1]失败：连接被拒绝：连接

127.0.0.1:8085是我设置为puty ssh隧道的地址和端口。但是我找不到从我的项目中删除此代理的设置在哪里。最后，幸运的是我在此文件（gradle.properties）中找到了它：

C：\ Users \ USERNAME.gradle \ gradle.properties

在此文件中，我删除了以下行：

systemProp.https.proxyPort=8085
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=8085

，问题消失。但是我还不知道gradle如何获得和设置代理设置！有人知道吗？

命令“离子cordova模拟android”不起作用
