Question

环境

• 操作系统: Windows Linux子系统，Ubuntu 18.04
• 贝壳:鱼
• 工具包管理: brew (自制/linuxbrew)
  • fish安装了
    • 鱼类已设置为默认外壳。

​

- brew had installed  
    - brew environment setting as [official site](https://docs.brew.sh/Homebrew-on-Linux) 
    - php had installed with brew
    - composer had installed with brew

​

​

目标

我想使用PHP与"php“命令，该命令brew已经安装，但失败。

我所做的一切

• 我试着自己设定环境

- Following success in current shell but fail when restart shell

在bash中，我尝试了这些PATH=${ PATH }:/home/linuxbrew/.linuxbrew/bin/ export PATH=${ PATH }:/home/linuxbrew/.linuxbrew/bin/ #，我尝试了以下设置路径：$PATH /home/linuxbrew/.linuxbrew/bin/ -update:更新后的导出路径$PATH:/home/linuxbrew/.linuxbrew/bin/ bin/ <-update:错误

- Following success in bash but fail in fish  
    - add the command above in .bashrc file in user directory (.bashrc seems only run when bash)

​

- Following should success but fail  
    - `sudo -H vi /etc/environment`
    - add `/home/linuxbrew/.linuxbrew/bin/` in it

Answer 1

如果您希望在启动fish时运行命令，则需要将它们放入~/..config/config.fish/中的一个名为"config.fish“的文件中。顾名思义，Bashrc是bash特有的。

此外，"export“用于标记”导出“变量，这意味着将其传递给shell启动的外部命令。$PATH通常是从启动shell的任何东西继承的，这意味着它无论如何都是导出的，所以您的export行是无用的。

另外，您的fish命令需要稍加调整：

set PATH $PATH /home/linuxbrew/.linuxbrew/bin/

$PATH在fish中是一个列表，因此它需要设置为多个参数，而不是一个字符串。在fish 3.0中(在Ubuntu18.04之后发布)，它被调整为自动拆分为":"，但即使在这种情况下，您也必须引用它，否则它将有令人惊讶的结果。
