Question

我最近将本机版本升级为

react-native upgrade

，并按照所有步骤进行操作，到目前为止没有任何错误。现在，当我要构建ios版本时，出现以下错误：

❌  ld: symbol(s) not found for architecture x86_64
❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

**生成失败**

以下构建命令失败：

Ld build/Build/Products/Debug-iphonesimulator/CustomName.app/CustomName normal x86_64

（1次失败）

The following commands produced analyzer issues:
Analyze Base/RCTModuleMethod.mm normal x86_64
Analyze RCTNetInfo.m normal x86_64
Analyze RCTImageCache.m normal x86_64
(3 commands with analyzer issues)

我的项目环境

React Native Environment Info: System: OS: macOS 10.14.3 CPU: (8) x64 Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz Memory: 140.02 MB / 16.00 GB Shell: 3.2.57 - /bin/bash Binaries: Node: 11.7.0 - /usr/local/bin/node Yarn: 1.13.0 - /usr/local/bin/yarn npm: 6.5.0 - /usr/local/bin/npm Watchman: 4.9.0 - /usr/local/bin/watchman SDKs: iOS SDK: Platforms: iOS 12.1, macOS 10.14, tvOS 12.1, watchOS 5.1 IDEs: Xcode: 10.1/10B61 - /usr/bin/xcodebuild npmPackages: react: 16.6.3 => 16.6.3 react-native: 0.58.5 => 0.58.5 npmGlobalPackages: create-react-native-app: 2.0.2 react-native-cli: 2.0.1 react-native-git-upgrade: 0.2.7 react-native-rename: 2.4.0

所以我检查了文件夹

build/Build/Products/Debug-iphonesimulator/

可以找到被系统禁用的.app文件（其他本机项目具有有效的.app文件）

因此，似乎该构建正在创建一个无效的.app文件，由于文件/文件夹不可用，该文件随后（可以理解）无法链接。

是否有机会获得详细的见解，是什么原因导致此无效的.app文件以及如何修复该文件？

任何提示都很感激！

Answer 1

Xcode Archive build failed with react native project

关于JavaScriptCore.framework的第一个答案可以挽救我的生命，希望如此：

Answer 2

您应将Private Sub Scanner1_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles Scanner1.DataReceived dataIn = Scanner1.ReadExisting SetText(dataIn) End Sub Delegate Sub SetTextCallback(ByVal text As String) Private Sub SetText(ByVal text As String) If Me.txtSearch.InvokeRequired Or Me.txtSearch1.InvokeRequired Then Dim d As SetTextCallback = New SetTextCallback(AddressOf SetText) Me.Invoke(d, New Object() {text}) Else Me.txtSearch.Text = text.ToString Me.txtSearch1.Text = text.ToString End If End Sub添加到JavaScriptCore.Framework-> Build Phases。
