zsh上找不到npm全局安装命令

macosnpmzshoh-my-zsh

我刚刚使用npm install -g live server安装了live-server包。

我检查过，该包当前已安装在以下路径：

/Users/username/.npm-global/lib/node_modules/live-server/live-server.js

但是，当我尝试从命令行运行live-server时，出现了错误：

zsh: command not found: live-server

我需要做什么才能运行live-server呢？我已经安装了oh-my-zsh，我担心这可能是导致问题的原因。我知道这应该与设置我的PATH有关，但我不确定具体是什么。

运行echo $PATH的结果如下：

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/opt/ImageMagick/bin:/Users/username/npm-global/bin:/Users/username/npm-global/bin:/Users/username/npm-global/lib

这里有一些可能相关的根目录中的文件。

谢谢。

为什么你的文件 .bashrc 或 .bash_profile 是相关的？如果你运行 zsh，当你加载一个交互式 shell 时，这些文件都不会被调用。只使用 .zshrc 或 .zprofile 来配置你的 zsh shell，就像 这个跨站点重复问题 中所示。 - Aserre
谢谢提醒，我会删除那些文件。 - Jon_B
你的 /Users/username/npm-global/bin 文件夹中有什么内容？另外，当你运行 bash 而不是 zsh 时，它是否有效？ - Aserre
顺便提一下，您的 shell 仅会读取 PATH 文件夹直接位于根目录下的文件。正如您在帖子中展示的那样，live-server.js 似乎位于子文件夹中，因此 zsh 不会知道它的存在。 - Aserre
另外，在/Users/username/npm-global/bin中，您在提问时是否打错了字？应该是/Users/username/.npm-global/bin（有一个点）。 - Aserre
非常感谢。将export PATH=$PATH:/Users/username/.npm-global/bin添加到.zshrc而不是.bashrc中已经解决了我的问题。 - Jon_B

将此添加到我的~/.zshrc文件中，问题得到了解决。
export PATH="$HOME/.npm-packages/bin:$PATH"

但是那个名为 .npm-packages 的文件夹不存在。 - Matteo

按照以下方式设置以防止进一步问题：

安装NVM来管理Node版本 使用--lts选项安装最新版本的node 再次安装最新版本的NPM

之后正确设置.zshrc文件。如果您使用zshell，请勿使用.bashrc，它有自己的配置文件，我认为您已经更新了它。

检查NPM页面https://www.npmjs.com/package/live-server，特别是这些部分：

Default options:
If a file ~/.live-server.json exists it will be loaded and used as default options for live-server on the command line. See "Usage from node" for option names.

Usage from node
var liveServer = require("live-server");
var params = ...

我忘记了我在使用nvm（Node版本管理器），但是我通过输入以下内容发现它：

where npm

这为我提供了当前npm安装路径。

/Users/myusername/.nvm/versions/node/v16.13.0/bin/npm

这意味着我的全局安装的包在 /Users/myusername/.nvm/versions/node/v16.13.0/lib/node_modules 中！

因此，我在我的 zshconfig 中执行了以下操作：

export PATH="$PATH":"$HOME/.nvm/versions/node/v16.13.0/lib/node_modules"

终端重启后，我的全局安装的包开始工作了！

注意：如果您更改了活动的节点版本（通过nvm use ...），它可能会破坏您全局安装的软件包。但是在更改节点版本后，您始终可以更新路径（如果这是一个长期更改）。
