标签： react-native

这是我的环境：

➜  AwesomeProject node --version
v6.3.0
➜  AwesomeProject npm --version
3.10.3
➜  AwesomeProject react-native --version
react-native-cli: 1.0.0
react-native: 0.29.0
➜  AwesomeProject watchman --version
3.0.0

Xcode version 7.3.1

我创建了https://facebook.github.io/react-native/docs/getting-started.html#content

上描述的AwesomeProject

然后执行：sudo react-native run-ios

这是我得到的：

当点击react-native run-ios时，打印到控制台的第一行之一就是这样（或类似的）

Launching iPhone 6 (10.0)...
  1. 手动启动相应的模拟器
    • 转到spotlight search并开始输入模拟器
    • 当聚光灯显示搜索结果时，选择模拟器应用程序并按Enter
    • 转到模拟器应用程序的菜单：Hardwire - ＆gt;设备 - ＆gt; iOS 10.0 - ＆gt; iPhone 6并选择它
  2. 复位
    • 转到模拟器应用程序的菜单：模拟器 - ＆gt;重置内容和设置...
  3. 重试
    • 再次命令react-native run-ios

答案 1 :(得分：7)

我刚刚解决了同样的问题。

首先尝试使用react-native run-ios代替sudo react-native run-ios。

接下来尝试以下操作：

在档案AppDelegate.m中，更改

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

致：

jsCodeLocation = [NSURL URLWithString:@"http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true"];

（这可能是iOS 9的安全问题）;

接下来尝试重置您的环境。

第一次运行react-native run-ios时遇到同样的问题 尝试硬件 - ＆gt;重新启动模拟器，然后再次运行。

答案 3 :(得分：5)

当我在终端多路复用器react-native run-ios中运行tmux时，我遇到了这个问题。我通过在没有react-native run-ios运行的普通终端标签中运行tmux来修复它。

尝试不将react-native run-ios命令作为root

运行

答案 5 :(得分：2)

我重新启动了模拟器，如上所述尝试配置重置，但没有运气。

然而，当模拟器打开时，我去了Sub StringExistsInFile() Dim theString As String Dim path As String Dim StrFile As String Dim fso As New FileSystemObject Dim file As TextStream Dim line As String theString = Sheets("PHILA_RESULT_PART_201703210429").Cells(i + 1, 2).Value path = "C:\Users\Jira\Desktop\LaPoste\20170324_120939_export_phila_commande.Envoi1\" StrFile = Dir(path & "*.xml") i = 1 Do While Sheets("PHILA_RESULT_PART_201703210429").Cells(i + 1, 2).Value <> "" Set file = fso.OpenTextFile(path & StrFile) Do While Not file.AtEndOfLine line = file.ReadLine If InStr(1, line, theString, vbTextCompare) > 0 Then Sheets("PHILA_RESULT_PART_201703210429").Cells(i + 1, 14).Value = "found" Else Sheets("PHILA_RESULT_PART_201703210429").Cells(i + 1, 14).Value = "not found" End If Loop i = i + 1 file.Close Set file = Nothing StrFile = Dir() Loop

在模拟器上拖动 AwesomeProject.app并且工作正常。

有一个类似的问题所以我在Xcode中打开它并从那里构建项目。问题是没有选择任何设备。当你尝试构建时，Xcode会告诉你。

答案 7 :(得分：0)

遇到同样的问题。 Hardware＆gt; Restart修正了它。

答案 8 :(得分：0)

这是一个老问题，但我知道人们甚至在今天遇到这个问题。发布我看到的解决方案。

尝试按原样在Mac上打开模拟器而不使用本地反应。如果您能够通过Xcode打开模拟器，您将能够通过react-native命令打开它。

我注意到我需要释放系统资源才能打开任何新的模拟器实例。我杀死了几个进程，能够通过Xcode打开模拟器，然后通过react-native。

祝你好运！
