尽管软件已安装,但终端仍出现“未找到命令”错误

我知道 ubuntu 自带 gnome-terminal。几天前,我开始遇到一个无法描述的新问题。我在日常生活中使用 vscode 代码编辑器。许多命令,如 npm、pnpm、yarn、rust -v 等,在 gnome-terminal 中不起作用,我用相同的用户名用 .bashrc 文件配置了所有内容。我还使用另一个终端应用程序,如 hyper,所有命令都不起作用。它显示一个错误,如下所示

// pnpm 
rajdeepsingh@officialrajdeepsingh:~$ pnpm -v
Command 'pnpm' not found, did you mean:
  command 'npm' from deb npm (8.5.1~ds-1)
Try: sudo apt install <deb name>
rajdeepsingh@officialrajdeepsingh:~$

// deno
rajdeepsingh@officialrajdeepsingh:~$ deno -v
Command 'deno' not found, but can be installed with:
sudo snap install deno
rajdeepsingh@officialrajdeepsingh:~$

但是所有命令在 vscode 终端上都可以正常工作。我还没有找到解决方案。 vscode

答案1

即使您设法解决了这个问题,我还是建议您尝试更好地了解这里到底发生了什么。首先,让我们回到您最初的错误消息:

Command 'pnpm' not found

发生这种情况的原因是您的 shell(可能是 bash)无法pnpm在它需要查找的任何地方找到二进制文件。那么它需要查找哪里呢?您只需查看变量中的内容即可找到答案$PATH

echo $PATH

相对正常的输出可能看起来像这样:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/var/lib/snapd/snap/bin:/root/bin

这是用冒号分隔的“查找位置”列表,因此您可以ls在终端中简单地写入,因为 bash 知道在其中一个文件夹中查找它并找到它。如果您想知道 bash 在哪里找到ls,您可以执行以下操作:

# whereis ls
ls: /usr/bin/ls (...)

所以,如果我是你,我会尝试弄清楚:

  1. 当您输入时您实际上希望发生什么pnpm,该二进制文件位于哪里?
  2. 确保该二进制文件所在的目录是 $PATH 变量的一部分

根据你问题中提供的输出,我假设你想要的pnpm意思是/home/rajdeepsingh/.local/share/pnpm/pnpm。首先,你可以通过运行二进制文件及其完整路径来测试这一点,例如:

$ /home/rajdeepsingh/.local/share/pnpm/pnpm

正如您在评论中提到的那样,位置是不是在您的 PATH 中,这解释了为什么 bash 不知道如何找到二进制文件:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin

这条道路不仅看起来完全不同,而且没有什么来自您的.bashrc。那么发生了什么?为什么您必须指定-i交互模式?

出色地,有这个在你的.bashrc

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

.bashrc我不知道你为什么会有这个,因为这不是我所知道的任何标准的一部分。一个基本的标准示例可能看起来像:

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# User specific environment
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
    PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
export PATH

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

因此,您必须运行的原因bash -i不是因为“它就是这样工作的”,而是因为您自己(或其他人)添加了一个约束,.bashrc如果您不运行,该约束就会退出bash -i

我的建议是:重新开始。创建一个新的.bashrc,并按照您的需要进行设置,因为它并不复杂,但您却把它弄得很复杂。

你的.bashrc 可以可能看起来像这样:

# Source global definitions (system-wide)
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# User specific environment (default)
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
    PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
export PATH

#( *** your config here, not related to PATH *** )

export PATH=$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin:$PATH
export PATH=/home/rajdeepsingh/.bun/bin:$PATH
export PATH=$PATH:$HOME/Android/Sdk/tools
export PATH=$PATH:/home/rajdeepsingh/Android/Sdk/platform-tools/
export PATH=/home/rajdeepsingh/.local/share/pnpm:$PATH
export PATH=/home/rajdeepsingh/.deno/bin:$PATH
export PATH=/home/rajdeepsingh/.surrealdb:$PATH

# export PATH="/usr/local/bin:$PATH" <- pointless, /usr/local/bin is part of
#                                       any normal path definition

尝试一下,source ~/.bashrc然后echo $PATH

答案2

终端和文件都很好.bashrc。但我的终端不使用 bash 解释器运行。所以我在 gnome-terminal 和超级终端中手动配置。

超级终端解决方案


// hyper.js

shell: "",

shellArgs: ['-i'],

gnome-terminal 解决方案 您可以使用自定义命令在 gnome-terminal 中添加 bash 解释器。您可以使用bash或“bash -i”;两者都可以正常工作。
