React Native ios运行报错

发现码云的好像有点问题，可以换成清华大学的试试：

周末因为MAC没电，所以一直都没折腾IOS的运行。今天充电了就赶紧试一下。

结果，一运行就报错：

> AwesomeProject@0.0.1 ios /Users/allahbin/ReactNativeProject/AwesomeProject
> react-native run-ios

error Could not find "Podfile.lock" at /Users/allahbin/ReactNativeProject/AwesomeProject/ios/Podfile.lock. Did you run "pod install" in iOS directory?

上面写了，Did you run "pod install" in iOS directory，好吧，很听话的去ios目录输入了pod install

然后就报错。。。

太难了。。。

反正拿着那个错误，大部分都是让去改Podfile这个文件，也就是这个

怎么改呢，直接在上面加一个码云的git地址，你要是觉得你的网好，你可以试试GitHub的。反正我是放弃了，这个太浪费我时间了。

之后，就慢慢等，它就会开始拉取代码，我们可以在这个目录看到拉取的项目

对了还会因为网不好出现这个错误：

然后就成功运行，可以愉快的玩耍了

这次的问题比之前的还要奇怪，我以及在pod上配置了source了，但是在下载一些东西的时候，还是会去GitHub中下载，这显然是有问题的。

为此我选择使用代理的形式来解决这些问题。

首先，在终端配置代理

export https_proxy=http://localhost:4780
export http_proxy=http://localhost:4780

注意，即使是 HTTPS 代理，URL 也可能以 http:// 开头。

虽然现在很少有从http去下载东西的操作，但是还是加上吧。

配置完成后，需要进行检查

echo $https_proxy

然后我们就可以正常pod install了！！！
