"command not found: webpack-dev-server" 的 webpack-dev-server 错误

Question

真的不明白为什么我无法将其发送到 运行...我已经完成了以下操作。

npm install -g webpack webpack-dev-server

确认两个都安装成功。

现在，当我尝试执行 webpack-dev-server 时，我得到以下信息：

$ webpack-dev-server --inline --hot
zsh: command not found: 'webpack-dev-server'

永远不要 运行 像我所有其他 npm 模块一样 load/run 很好，无论是本地还是全局。我也尝试将它本地安装到项目中（添加到 package.json、npm install、yadda yadda..）并收到相同的错误。

我是不是漏掉了什么？

根据 this answer on GitHub 找到解决方案：

I was able to solve this problem on my machine. It appears to have been an issue with permissions.

I installed webpack and webpack-dev-server globally. However, even then, $ webpack-dev-server resulted in command not found (as stated above).

The problem was that npm installed the global packages to /usr/local/lib/node_modules which required root permissions.

In order to avoid having to use root permissions, I changed the directory in which global packages are to be installed to a directory in $HOME. To do this, I followed this guide: https://github.com/sindresorhus/guides/blob/master/npm-global-without-sudo.md

I installed webpack and webpack-dev-server globally again (this time without sudo) and verified that they have been installed in my new directory.

Now, I can finally run $ webpack-dev-server.

问题是 npm 将全局包安装到 /usr/local/lib/node_modules，这需要 root 权限。 为避免这种情况，您可以使用 Use sudo npm i -g webpack webpack-dev-server。
它对我有用。
