在 zsh 上找不到 npm 全局安装命令

Question

我刚刚使用npm install -g live server

我检查了，该软件包当前安装在

/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 时出现错误

zsh: command not found: live-server

我需要做什么才能运行实时服务器？ 我安装了 oh-my-zsh，我担心这可能会导致我的问题。 我知道它应该与设置我的 PATH 有关，但我不确定是什么。

运行echo $PATH会导致：

/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

以下是我的根目录中可能相关的一些文件。

谢谢

Answer 1

将export PATH=$PATH:/Users/username/.npm-global/bin到 .zshrc 而不是 .bashrc 解决了我的问题

Answer 2

将此添加到我的 ~/.zshrc 为我修复了它

export PATH="$HOME/.npm-packages/bin:$PATH"

Answer 3

以这种方式设置它以防止进一步的问题：

安装 NVM 以管理节点版本 使用 --lts 安装节点，以便获取最新版本 再次安装 NPM 最新版本

之后正确设置 .zshrc 文件。 如果您使用 zshell，请不要使用 .bashrc，它有自己的配置文件，我想您已经更新了它。

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 = ...

Answer 4

我忘记了我使用的是nvm （节点版本管理器），但我通过键入以下内容找到了它：

where npm

这给了我当前 npm 安装的路径。

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

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

所以，我在我的 zshconfig 中这样做了：

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

重新启动终端后，我的全局安装包开始工作！ 🚀

注意：如果你改变你的活动节点版本（通过nvm use ... ），它可能会弄乱你全局安装的包。 但是您总是可以在更改节点版本后更新路径（如果是长期更改）。
