我正在使用 Ubuntu 16.04，并尝试通过运行以下命令安装 vue-cli：
npm install -g vue-cli
这是输出：
npm WARN deprecated [email protected]: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
/home/gabriel/.npm-global/bin/vue-init -> /home/gabriel/.npm-global/lib/node_modules/vue-cli/bin/vue-init
/home/gabriel/.npm-global/bin/vue -> /home/gabriel/.npm-global/lib/node_modules/vue-cli/bin/vue
/home/gabriel/.npm-global/bin/vue-list -> /home/gabriel/.npm-global/lib/node_modules/vue-cli/bin/vue-list
+ [email protected]
updated 2 packages in 18.669s
（我再次运行该命令以获取输出，这就是它显示已更新的原因）
但是，终端无法识别命令“vue”：
No command 'vue' found, did you mean:
Command 'vpe' from package 'texlive-latex-extra' (universe)
vue: command not found
目录 /home/gabriel/.npm-global/lib/node_modules/vue-cli/bin/vue-init 包含：
-rwxrwxr-x 1 gabriel gabriel 380 jun 4 22:47 vue*
-rwxrwxr-x 1 gabriel gabriel 309 oct 1 2017 vue-build*

-rwxrwxr-x 1 gabriel gabriel 3.9K feb 4 2018 vue-init*
-rwxrwxr-x 1 gabriel gabriel 775 oct 1 2017 vue-list*
每当我尝试安装任何新的 CLI 时，都会发生这种情况。Laravel 安装程序也会发生这种情况，如果我尝试运行安装命令，它会告诉我它已经安装，但就像 vue-cli 一样，它无法识别该命令：
gabriel@gabriel /v/w/h/test> composer global require "laravel/installer"
Changed current directory to /home/gabriel/.config/composer
You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug
Using version ^2.0 for laravel/installer
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
gabriel@gabriel /v/w/h/test> laravel new app
laravel: command not found
以前不会发生这种情况。例如，因为我能够成功安装 composer 和 npm。
什么原因导致了这个问题？
提前致谢！
编辑。- 我尝试在 ~/.profile 中将环境变量添加到 PATH，但这似乎也不起作用。文件如下所示：
# set PATH so it includes user's private bin directories
PATH="$HOME/bin:$HOME/.local/bin:$HOME/.npm-global/lib/node_modules/vue-cli/bin:$PATH"
# Ubuntu make installation of Ubuntu Make binary symlink
PATH=/home/gabriel/.local/share/umake/bin:$PATH
