找不到ngrok命令 [英] ngrok command not found
问题描述
我正在尝试在1周大的优胜美地上安装ngrok(在Windows上已经使用了一段时间，没有任何问题)，这是我到目前为止所遵循的步骤.
I'm trying to install ngrok (which I've been using for a while on Windows with no issues) on my 1 week old yosemite and these are the steps I've followed so far.
-
从此处 https://ngrok.com/download 下载ngrok.
解压缩文件并将Unix可执行文件复制到 应用程序.
Unziped the file and copied the Unix Executable File into application.
现在，据我了解，我只需要打开终端，在应用程序文件夹内移动并编写ngrok http 80.结果是找不到命令".
Now from what I understand I just need to open the terminal, move inside the application folder and write ngrok http 80. The result of this is "command not found".
我什至已经在ngrok网站上注册并从终端运行命令./ngrok authtoken "blablabla"，结果是没有这样的文件或目录"
I've even signed up at the ngrok website and run from terminal the command ./ngrok authtoken "blablabla" and the result is "No such file or directory"
有人可以告诉我如何继续使用ngrok激活隧道吗?
Can anyone tell me how to proceed to be able to activate the tunnel with ngrok?
推荐答案
简短答案:将可执行文件放置在/usr/local/bin中，而不是应用程序中.现在，您应该能够运行ngrok http 80之类的命令.
Short answer: Put the executable file in /usr/local/bin instead of applications. You should now be able to run commands like ngrok http 80.
长答案:当您在终端中键入ngrok之类的命令时，Mac(和其他Unix OS)会在PATH中指定的文件夹中查找这些程序. PATH是每个用户指定的文件夹列表.要检查路径，请打开终端并输入:echo $PATH.
Long answer: When you type commands like ngrok in the terminal, Macs (and other Unix OSs) look for these programs in the folders specified in your PATH. The PATH is a list of folders that's specified by each user. To check your path, open the terminal and type: echo $PATH.
您将看到类似于以下内容的输出:/usr/local/bin:/usr/bin:/bin.这是:分隔的文件夹列表.
You'll see output that looks something like: /usr/local/bin:/usr/bin:/bin. This is a : separated list of folders.
因此，当您在终端中键入ngrok时，Mac将在以下文件夹中寻找此可执行文件:/usr/local/bin，/usr/bin/和/bin.
So when you type ngrok in the terminal, your Mac will look for this executable in the following folders: /usr/local/bin, /usr/bin/ and /bin.
