-bash: react-native: command not found
提问by loungeonbench
I have successfully installed brew, node 4.0+, watchman and flow, and I received the following when I do npm install -g react-native-cli:
我已经成功安装了 brew、node 4.0+、watchman 和 flow，我在安装时收到以下信息npm install -g react-native-cli：
/Users/home/.node/bin/react-native -> /Users/home/.node/lib/node_modules/react-native-cli/index.js
[email protected] /Users/home/.node/lib/node_modules/react-native-cli
└── [email protected] ([email protected], [email protected], [email protected], [email protected], [email protected])
So I assume react-native-clihas been successfully installed as well. However when I run react-native, it says:
所以我假设react-native-cli也已成功安装。但是，当我运行时react-native，它说：
-bash: react-native: command not found
My node version is 4.2.1, watchman 3.9, brew 0.9.5 (git 7ed6) and npm 2.14.7
我的节点版本是 4.2.1，watchman 3.9，brew 0.9.5 (git 7ed6) 和 npm 2.14.7

You have to make sure /usr/local/share/npm/binis in your PATHto use binaries installed with npm.
您必须确保/usr/local/share/npm/bin在您PATH使用的二进制文件中安装了npm.
Add the following to your ~/.bashrc:
将以下内容添加到您的~/.bashrc:
export PATH="/usr/local/share/npm/bin:$PATH"
And reload your shell session.
并重新加载您的 shell 会话。
If you find you don't have a /usr/local/share/npm/bindirectory, your npmmay install its packages in another location. In this case you have to use the right path in the line above.
如果你发现你没有/usr/local/share/npm/bin目录，你npm可以在另一个位置安装它的包。在这种情况下，您必须使用上一行中的正确路径。
One solution to find that path is to run:
找到该路径的一种解决方案是运行：
npm list -g | head -n 1
This gives you the path where npminstall its packages. This is not the path you want but it's close. For example on my Linux it gives /home/baptiste/.linuxbrew/lib; it suffices to replace libwith binto get the correct path:
这为您提供了npm安装其软件包的路径。这不是你想要的路径，但它很接近。例如在我的 Linux 上，它给出了/home/baptiste/.linuxbrew/lib; 只需替换libwithbin即可获得正确的路径：
export PATH="/home/baptiste/.linuxbrew/bin:$PATH"

I tried many ways to work out a solution to this on my mac(node -v: v8.1.3, npm -v: 5.0.3). And when I ran npm install -g react-native-cli, the output was this:
我尝试了很多方法来在我的 mac( node -v: v8.1.3, npm -v: 5.0.3)上找到解决方案。当我运行时npm install -g react-native-cli，输出是这样的：
/Users/xxx/.npm-packages/bin/react-native -> /Users/xxx/.npm-packages/lib/node_modules/react-native-cli/index.js + [email protected] updated 1 package in 2.988s
/Users/xxx/.npm-packages/bin/react-native -> /Users/xxx/.npm-packages/lib/node_modules/react-native-cli/index.js + [email protected]在 2.988 秒内更新了 1 个包
As you can see react-nativewas install in /Users/xxx/.npm-packages/bin/, different from what others may say. So I pasted the line export PATH=/Users/xxx/.npm-packages/bin:$PATHto my ~/.profileand opened a new Terminal window to run react-native. It worked!
如您所见react-native，安装在 中/Users/xxx/.npm-packages/bin/，与其他人可能说的不同。所以我将该行粘贴export PATH=/Users/xxx/.npm-packages/bin:$PATH到 my~/.profile并打开一个新的终端窗口来运行react-native. 有效！

First of all, you have to install react native globally
首先，你必须全局安装react native
npm install -g react-native-cli
then it will show you the path for the react native like the following
然后它会向您显示 react native 的路径，如下所示
/Users/{yourUser}/.npm-packages/bin/react-native -> /Users/{yourUser}/.npm-packages/lib/node_modules/react-native-cli/index.js
Then you have to set the default path from the above result and execute the following command
然后你必须从上面的结果中设置默认路径并执行以下命令
export PATH="/Users/{yourUser}/.npm-packages/bin/:$PATH"
or
或者
export PATH="$HOME/.npm-packages/bin:$PATH"
Then reload you session/env vairables
然后重新加载会话/环境变量
source ~/.bash_profile
It works for me .... cheers
它对我有用......欢呼
thanks
谢谢

export PATH="$HOME/.npm-packages/bin:$PATH" worked for me however, I had to replace packages with what was on my mac.
export PATH="$HOME/.npm- packages/bin:$PATH" 对我有用，但是，我不得不用我的 mac 上的包替换包。
i.e .npm-globalinstead of .npm-packages. ..
即 .npm-global而不是 .npm- packages。..
