英文:
Why can't I run the go binary from within the /bin directory?
问题
我下载了适用于OSX 10.12.2的go1.7.5.darwin-amd64.tar.gz文件。
解压缩tar文件后，我进入/bin目录，查看Go可执行文件是否可以运行。
$ cd Downloads/go/bin
$ ls
总计 54560

英文:
I downloaded go1.7.5.darwin-amd64.tar.gz for osx 10.12.2.
Unpacked the tar and went to the /bin directory to see if the Go executable would run.
$ cd Downloads/go/bin
$ ls

得分: 3
当您在不提供完整路径的情况下输入命令时，您的系统将尝试在$PATH变量提供的所有文件夹中查找该命令。
在典型的Unix环境中，您的$PATH不包括"当前文件夹"。因此，您需要执行以下操作之一：
-
使用完整路径调用go（例如
$HOME/Downloads/go/bin/go）；或者 -
使用相对路径调用go（例如
./go）；或者 -
将
$HOME/Downloads/go/bin添加到您的$PATH变量中；或者 -
将
.（Unix中表示"当前文件夹"）添加到您的$PATH中；或者 -
将go二进制文件放入已经在您的
$PATH中的文件夹中。例如：sudo cp $HOME/Downloads/go/bin/* /usr/local/bin/.
英文:
When you type a command without giving the full path, your system will try to find it within all the folders provided in $PATH variable.
In typical Unix environment, your $PATH does not include "your current folder". So you need to either:
-
call go by its full path (i.e.
$HOME/Downloads/go/bin/go); or -
call go by its relative path (i.e.
./go); or -
put
$HOME/Downloads/go/binin your$PATHvariable; or -
put
.(Unix way of saying "your current folder") in your$PATH; or -
put your go binary into folders that already in your
$PATH. For examplesudo cp $HOME/Downloads/go/bin/* /usr/local/bin/.

sudo chmod +x go
看起来它没有执行权限，所以只需更改权限并运行它，然后你应该将go二进制路径设置为环境变量，以便在任何地方都可以访问二进制文件。
英文:
sudo chmod +x go
seems like it does not have execute permission, so just change permission and run it then you should alias your go binary path to your environment to access binary every where.
