创建反应应用程序，安装错误（“未找到命令”） [英] create-react-app, installation error ("command not found")

问题描述

我已经按照facebook指示页面上的指示安装了创建反应应用程序（ https://facebook.github.io/react/blog/2016/07/22/create-apps-with-no-configuration.html ）：

I have installed create-react-app exactly as instructed on the facebook instruction page (https://facebook.github.io/react/blog/2016/07/22/create-apps-with-no-configuration.html):

首先，安装全球包：

First, install the global package:

npm install -g create-react-app

我这样做了。它似乎工作正常 - 文件安装到

I did this. It appeared to work fine - the file was installed to

users/*name*/.node_modules_global/lib/node_modules/create-react-app

我不太确定为什么全局安装将其带到这个路径，但是在那里

I'm not really sure why global install takes it to this path, but there you have it.

下一条说明：

现在可以使用它来创建一个新的应用程序：

Now you can use it to create a new app:

create-react-app hello-world

不能简单，对吧？但是终端在我身上吐了出来：

Couldn't be simpler, right? But Terminal spits out this at me:

-bash: create-react-app: command not found

这可能是一件非常简单的事情，但我不知道在哪里看。如果有人可以帮助我真的很感激！

It's probably something very simple I'm missing but I don't really know where to look. If anyone can help I'd really appreciate it!

提前感谢

注意：我正在使用Node v6.3.1和npm v3.10.3

推荐答案

您的节点设置看起来不正确。这不是创建React应用程序的问题 - 似乎您无法运行任何全局Node命令。

Your Node setup looks incorrect. It's not an issue with Create React App—it seems like you can't run any global Node commands.

它看起来像〜/ .node_modules_global / bin 不在您的 PATH 环境变量中，因此无法执行全局命令。这就是Bash的工作原理 - 它不能猜测命令在哪里，你需要告诉它。我会假设Node安装应该默认这样做，但这取决于您如何安装Node。

It looks like ~/.node_modules_global/bin is not in your PATH environment variable so it can't execute global commands. That's just how Bash works—it can't guess where the command lies, you need to tell it. I would assume Node installation should do this by default but it depends on how you installed Node.

所以确保该目录位于您的 PATH ，然后重试。如果您使用Bash，请将其添加到您的 .profile 中，然后重新启动终端：

So make sure that directory is in your PATH and try again. If you use Bash, add this to your .profile and then restart the Terminal:

export PATH=$HOME/.node_modules_global/bin:$PATH
