According to my research, this is a node.js version issue: I should have use v.4.0+.
根据我的研究，这是一个 node.js 版本问题：我应该使用 v.4.0+。
I am using NVM to manage my node.js versions. In regular terminal window, I have this:
我正在使用 NVM 来管理我的 node.js 版本。在常规终端窗口中，我有这个：
$ node --version
v5.1.0
but in xcode when it run the start shell script, I saw it is using a different version, v0.10.40, and xcode doesn't know about nvmcommand either..
但是在 xcode 中，当它运行启动 shell 脚本时，我看到它使用了不同的版本v0.10.40，并且 xcode 也不知道nvm命令......
The question is, how should I configure my Mac so the xcode can pick up the same version that I set with nvm?
问题是，我应该如何配置我的 Mac 以便 xcode 可以选择我使用 nvm 设置的相同版本？
Thank you!
谢谢！
Update: I tried to sourcemy ~/.bash_profilein the shell script executed by xcode, but still not solving the problem.
更新：我尝试在 xcode 执行的 shell 脚本中执行source我~/.bash_profile的操作，但仍然没有解决问题。

I resolved the issue by adding . ~\.bash_profileto the top of shell script.
我通过添加. ~\.bash_profile到 shell 脚本的顶部解决了这个问题。

The problem seems to occur when you have installed react-native-cli with the wrong Node (and thus npm) version.
当您使用错误的 Node（以及 npm）版本安装 react-native-cli 时，似乎会出现此问题。
First shut down xcode and let's make sure that there is no old node processes running, I'm not sure if this is necessary but it is good to make sure:
首先关闭 xcode，让我们确保没有旧的节点进程在运行，我不确定这是否有必要，但最好确保：
$ ps -e|grep node
$ kill {process number(s) here}
Then set the default nvm node version to the one you want to use, for example:
然后将默认的 nvm 节点版本设置为您要使用的版本，例如：
$ nvm alias default 6.6.0
Then restart your terminal and make sure that the node version is now the one you want by default:
然后重新启动您的终端并确保节点版本现在是您默认所需的版本：
$ node -v
v6.6.0
Now reinstall react-native-cli with the new node version active (it affects the npm version):
现在重新安装 react-native-cli 并激活新的节点版本（它会影响 npm 版本）：
$ npm install -g react-native-cli
Now running $ react-native run-iosshould run xcode with the proper version! (If it doesn't, make sure to restart your terminal/xcode and try again).
现在运行$ react-native run-ios应该使用正确的版本运行 xcode！（如果没有，请确保重新启动终端/xcode 并重试）。

I resolved by adding . ~/.nvm/nvm.shto the top of the shell script in Build Phases
我通过. ~/.nvm/nvm.sh在 Build Phases 中添加到 shell 脚本的顶部来解决

For me, adding this to /etc/profileor to ~/.profileworked:
对我来说，将此添加到/etc/profile或~/.profile工作：
export NVM_DIR="$HOME/.nvm"
[ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh"
The reason this is necessary is because XCode uses /bin/shby default and it loads the profiles from the files I specified.
这是必要的原因是因为 XCode/bin/sh默认使用并且它从我指定的文件中加载配置文件。
Note: altering /etc/profilerequires you to use sudo. Not sure if this is even possible on MacOS X 10.15 Catalina since I believe they made the system directories to be read-only, no matter what. But if you are able to set it here, this will make it work for any user who has nvm installed.
注意：更改/etc/profile需要您使用sudo. 不确定这在 MacOS X 10.15 Catalina 上是否可行，因为我相信他们将系统目录设为只读，无论如何。但是如果你能在这里设置它，这将使它适用于任何安装了 nvm 的用户。

Seeing as this is the top result in Google while searching for this error, the following is the only thing that worked for me.
看到这是搜索此错误时 Google 中的最佳结果，以下是唯一对我有用的方法。
I had to uninstall node (that was previously installed with the pkg from the Node website), uninstall nvm and reinstall node with Brew.
我必须卸载节点（之前从 Node 网站使用 pkg 安装），卸载 nvm 并使用 Brew 重新安装节点。
