Set an environment variable in git bash
提问by bier hier
When I punch from the windows gitbash command line:
当我从 windows gitbash 命令行打孔时：
set $HOME = c
and do :
并做：
echo $HOME
It does not set it to c? How can I change/set the value of an environment variable?
它没有将其设置为c? 如何更改/设置环境变量的值？

A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =:
普通变量通过简单地赋值来设置；请注意， 周围不允许有空格=：
HOME=c
An environment variable is a regular variable that has been marked for export to the environment.
环境变量是已标记为导出到环境的常规变量。
export HOME
HOME=c
You can combine the assignment with the exportstatement.
您可以将赋值与export语句结合起来。
export HOME=c

If you want to set environment variables permanently in Git-Bash, you have two options:
如果你想在 Git-Bash 中永久设置环境变量，你有两个选择：
Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.
Set up env variables in
.bash_profilefile.
设置一个常规的 Windows 环境变量。Git-bash 在启动时获取所有现有的 Windows 环境变量。
在
.bash_profile文件中设置环境变量。
.bash_profileis by default located in a user home folder, like C:\users\userName\git-home\.bash_profile. You can change the path to the bash home folder by setting HOMEWindows environment variable.
.bash_profile默认情况下位于用户主文件夹中，例如C:\users\userName\git-home\.bash_profile. 您可以通过设置HOMEWindows 环境变量来更改 bash 主文件夹的路径。
.bash_profilefile uses the regular Bash syntax and commands
.bash_profile文件使用常规的 Bash 语法和命令
# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir
# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"

Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.
在您的主目录中创建 .bashrc 文件也有效。这样您就不必每次安装新版本的 git bash 时都复制 .bash_profile。
