ndk 升级到17导致缺少配置文件，造成上述问题。

详细报错信息：

分析：

java IO异常，找不到文件或者目录。一般报这种问题，都是缺少文件。既然是缺少文件，那我们向上看，看看缺少哪些文件或者目录，找到了这个路径：/Users/alaska/Library/Android/sdk/ndk-bundle/toolchains/mips64el-linux-android-4.9/prebuilt/darwin-x86_64/

上面这个目录下缺少文件，只到了.../prebuilt/darwin-x86_64/这个层级，缺少.../prebuilt/darwin-x86_64/bin/mips64el-linux-android-strip

解决办法：

将SDK中的NDK回退到16b版本，去这里下载16b版本的ndk文件 

https://developer.android.com/ndk/downloads/older_releases

解压之后，替换掉原来SDK中的ndk-bundle文件，即.../Android/sdk/ndk-bundle/

或者将解压后的.../prebuilt/darwin-x86_64/，复制过去，这样17版本的ndk也具有了预编译mips so文件的能力
