Question

我正在尝试仅通过遵循此处的指南来建立一个新的React Native项目：https://facebook.github.io/react-native/docs/getting-started

我可以从Xcode很好地构建和运行它，只得到一些“语义警告”。

虽然我运行yarn react-native run-ios时遇到以下错误：

Leos-MacBook-Pro:citymysteryrn leo$ yarn react-native run-ios

我知道有很多与此相关的问题（和答案），但这似乎是我无法解决的非常广泛的问题。我在Print: Entry, ":CFBundleIdentifier", Does Not Exist上尝试了大多数操作，没有任何运气。

我也尝试过将这个项目与我知道正在运行的较旧的React Native项目进行比较，并确定了以下差异，但是不知道它们是否具有重要意义：

third-party中缺少文件夹node_modules/react-native/
构建文件夹包含文件夹ios/build/MyProjectName，其中包含Logs，info.plist等，而旧项目则直接在ios/build/中包含这些文件和文件夹

这是yarn react-native info

的输出

/ios/MyProjectName/Info.plist中的

CFBundleIdentifier如下：

<key>CFBundleIdentifier</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>

Answer 1

这不是适当的解决方案，但是。

我受够了，备份了MacBook，然后将整个东西擦干净了。现在可以使用了。

Fresh React Native项目失败：条目“：CFBundleIdentifier”不存在
