react-native：找不到命令 [英] react-native: command not found

问题描述

创建react-native项目时，我收到 -bash：react-native：command not found error 。

I am getting -bash: react-native: command not found error while creating react-native project.

以下是其他信息

1. brew --version
   homebrew 0.9.9
2  brew info watchman
   watchman `enter code here`stable 4.50
   /usr/local/Cellar/watchman/4.4.0
3. brew info flow
   stable 0.24.1
   /usr/local/Cellar/flow/0.24.1
4. brew info node
   stable 6.1.0
   /usr/local/Cellar/node/6.1.0
5. npm -version
   3.8.6
6. echo $PATH
/Users/Ashok/.rbenv/shims:/Users/Ashok/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

我尝试了从以下链接建议的步骤，但我仍然得到同样的错误。

I tried suggested steps from the below link but still i am getting same error.

1. ​​ react-native-command-not-found

1. react-native-command-not-found

我没有他们在解决方案中指定的任何npm目录

I don't have any "npm" directory which they have specified in the solution

Ashoks-MacBook-Pro:share Ashok$ ls
aclocal     doc     info        ruby-build  zsh
autoconf    emacs       man     systemtap

但我发现npm文件存在于以下位置。

But i found npm file exist in below location.

/usr/local/Cellar/node/6.1.0/etc/bash_completion.d

我卸载了react-native并再次安装，但我仍面临同样的问题。

I uninstalled react-native and installed again but still i am facing same issue.

推荐答案

在向PATH变量添加正确路径之后，问题就解决了。

以下是找到正确路径的步骤。

1. Enter: npm install -g react-native-cli
output: /usr/local/Cellar/node/6.1.0/libexec/npm/bin/react-native ->/usr/local/Cellar/node/6.1.0/libexec/npm/lib/node_modules/react-native-cli/index.js/usr/local/Cellar/node/6.1.0/libexec/npm/lib
└── react-native-cli@0.2.0 

从上面输出你可以清楚地看到路径： /usr/local/Cellar/node/6.1.0/libexec/npm/bin/react-native

from above output you can clearly see the path: /usr/local/Cellar/node/6.1.0/libexec/npm/bin/react-native

export PATH="/usr/local/Cellar/node/6.1.0/libexec/npm/bin:$PATH"

react-native init appName

cd appName

react-native run-ios

如果您 xcrun：错误：无法在此阶段找到实用程序simctl，您可以使用以下步骤重新开始

if you getting xcrun: error: unable to find utility "simctl" at this stage you can reslove using below steps

XCode - >首选项 - >位置 - >命令行工具 - >选择Xcode 7.2.1

您可以从 xcrun无法找到simctl
