我认为最优雅的方式是:

把这个加到~中。/ bashrc文件(: If [-d "new-path"];然后 = $ PATH:新路径 fi * ~ / . bashrc *来源

我的回答是关于在Ubuntu Linux (amd64)上设置Go环境。我曾经遇到过设置环境变量(GOPATH和GOBIN)路径的相同麻烦，每次在终端退出时丢失它，并使用source <file_name>重新构建它。

错误在于将路径(GOPATH和GOBIN)放在~/中。bash_profile文件。在浪费了几个小时之后，我发现解决方案是将GOPATH和GOBIN放在~/中。Bash_rc文件的格式如下:

export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOPATH:$GOBIN

在这样做的过程中，Go安装工作得很好，没有路径丢失。

与此问题相关的原因是，对于非登录shell的设置，比如我们运行Go代码的Ubuntu终端或GNOME终端，是从~。/bash_rc文件和登录shell的设置是从~/中获取的。bash_profile文件。从~/。如果~/. Profile文件。Bash_profile文件不可达。

有很多种方法。实际的解决方案取决于目的。

变量值通常存储在赋值列表中或在系统或用户会话开始时运行的shell脚本中。对于shell脚本，您必须使用特定的shell语法和导出或设置命令。

系统范围

/etc/environment List of unique assignments. Allows references. Perfect for adding system-wide directories like /usr/local/something/bin to PATH variable or defining JAVA_HOME. Used by PAM and systemd. /etc/environment.d/*.conf List of unique assignments. Allows references. Perfect for adding system-wide directories like /usr/local/something/bin to PATH variable or defining JAVA_HOME. The configuration can be split into multiple files, usually one per each tool (Java, Go, and Node.js). Used by systemd that by design do not pass those values to user login shells. /etc/xprofile Shell script executed while starting X Window System session. This is run for every user that logs into X Window System. It is a good choice for PATH entries that are valid for every user like /usr/local/something/bin. The file is included by other script so use POSIX shell syntax not the syntax of your user shell. /etc/profile and /etc/profile.d/* Shell script. This is a good choice for shell-only systems. Those files are read only by shells in login mode. /etc/<shell>.<shell>rc. Shell script. This is a poor choice because it is single shell specific. Used in non-login mode.

用户会话

~/.pam_environment. List of unique assignments, no references allowed. Loaded by PAM at the start of every user session irrelevant if it is an X Window System session or shell. You cannot reference other variables including HOME or PATH so it has limited use. Used by PAM. ~/.xprofile Shell script. This is executed when the user logs into X Window System system. The variables defined here are visible to every X application. Perfect choice for extending PATH with values such as ~/bin or ~/go/bin or defining user specific GOPATH or NPM_HOME. The file is included by other script so use POSIX shell syntax not the syntax of your user shell. Your graphical text editor or IDE started by shortcut will see those values. ~/.profile, ~/.<shell>_profile, ~/.<shell>_login Shell script. It will be visible only for programs started from terminal or terminal emulator. It is a good choice for shell-only systems. Used by shells in login mode. ~/.<shell>rc. Shell script. This is a poor choice because it is single shell specific. Used by shells in non-login mode.

登录Shell和非登录Shell的区别?

我昨天在寻找一种方法将包含我自己的脚本的文件夹添加到PATH时偶然发现了这个问题-并且惊讶地发现我自己的~/。配置文件(在Linux Mint 18.1上)已经包含这个:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

因此，我所要做的就是创建文件夹~/bin并将脚本放在那里。

您可以将这一行添加到控制台配置文件(例如，.bashrc或.profile)。

我认为最优雅的方式是:

将此添加到~/。bashrc文件。( 执行如下命令: 中~ / . bashrc 在里面添加你的路径: 导出路径= $路径:/ bin / opt /节点 源~ / . bashrc
