英文:
exec: "firefox": executable file not found in $PATH
问题
我正在阅读一本关于编写命令行工具的 Go 书籍。在其中一个示例中，我需要使用 Firefox 浏览器打开一个 HTML 文件。运行的命令如下：
browserPath,_ := exec.LookPath("firefox")
// 在浏览器中打开文件
if err := exec.Command(browserPath, "index.html").Start(); err != nil {
return err
}
但是出现了以下错误：
exec: "firefox": 在 $PATH 中找不到可执行文件
我的 $PATH 设置如下：
$HOME/bin:/usr/local/bin:$PATH
我在 Mac 上使用 zsh。我查看了类似的问题，但还没有解决，有人看出我漏掉了什么吗？
英文:
I am reading a go book to learn go writing command line tools. In one of the examples I need to open firefox browser with an html file. The command run is:
browserPath,_ := exec.LookPath("firefox")
// Open the file on the browser
if err := exec.Command(browserPath, "index.html").Start(); err != nil {
return err
}
But get the error:
exec: "firefox": executable file not found in $PATH
My $PATH is:
$HOME/bin:/usr/local/bin:$PATH
I am running on mac with zsh. I looked at similar problems but can't solve it yet, anyone see what I am missing?

首先，感谢您重新打开这个问题，我明白对许多人来说可能很简单，但它可以帮助其他人看到这个答案。
问题是（正如@xarantolus评论的那样），我的PATH没有包含到我的/Applications文件夹的路径。由于我使用的是zsh和Mac，我采取了以下步骤来解决这个问题：
首先找到firefox可执行文件的位置：
$ type -a firefox
打印的路径为：
firefox is /Applications/Firefox.app/Contents/MacOS/firefox
现在打开zshrc文件：
$ vim ~/.zshrc
在文件中，我的$PATH是$HOME/bin:/usr/local/bin:$PATH，我添加了/Applications，所以该行最终变成了这样：
export PATH=$HOME/bin:/usr/local/bin:/Applications/:$PATH
注意，在添加新路径后，:$PATH也将位于末尾。
然后运行命令重新加载.zshrc文件：
source ~/.zshrc
如果您不使用zsh，请使用.bashrc文件代替.zshrc。
现在，Go应该能够看到firefox可执行文件，并按预期打开它。
英文:
First of all thank you for reopening the question, I understand it might be trivial to many, but it can help someone else to see this answer.
The issue was (as @xarantolus commented) that my PATH did not contain the route to my /Applications folder. Since I use zsh and mac, I did the following steps to fix it:
First find where firefox executable was:
$ type -a firefox
Printed route:
firefox is /Applications/Firefox.app/Contents/MacOS/firefox
Now open zshrc file:
$ vim ~/.zshrc
Inside the file, my $PATH was $HOME/bin:/usr/local/bin:$PATH, and I added /Applications so the line ended up like this:
export PATH=$HOME/bin:/usr/local/bin:/Applications/:$PATH
Notice that :$PATH will be at end also after adding the new path
Then run command to reload .zshrc
source ~/.zshrc
If you dont use zsh, use the file .bashrc instead of .zshrc
Go could now see the firefox executable and it opened it as expected.

在Mac上，有一个可用的命令叫做open，它可以打开默认的浏览器。
我和你有同一本书。我希望作者能修复这个问题。无论主机操作系统如何，都能够打开默认的浏览器会很好。可能有一种方法。我没有查找类似于Linux或Windows上的open命令。

英文:
On Mac you have a command available called open which opens the default browser.
I have the same book as you. I hope the author fixes this. Would be nice to open the default browser regardless of the host operating system. There might be a way. I didn't look for a command similar to open on linux or windows.
