为什么？
And, I use this way can't find webpack:
而且，我用这种方式找不到webpack：
npm list -g | grep webpack

在包含以下内容的目录下运行此命令后package.json：
npm uninstall webpack
npm WARN [email protected] requires a peer of webpack@1 || 2 || ^2.1.0-beta || ^2.2.0-rc but none was installed.
npm WARN [email protected] requires a peer of uglify-js@^2.8.0 but none was installed.
npm WARN [email protected] requires a peer of webpack@^1.9 || ^2 || ^2.1.0-beta || ^2.2.0-rc but none was installed.

Try running both the below:
尝试运行以下两个：
npm uninstall -g webpack
npm uninstall webpack
I think you might be checking/lloking at the local version after deleting only the global one.
我认为您可能会在仅删除全局版本后检查/查看本地版本。

npm uninstall -g webpack
Worked for me, try running the command prompt in administrator mode.
对我来说有效，尝试在管理员模式下运行命令提示符。

Try
尝试
chown -R "$(whoami)": "$(npm root -g)"
(you may need sudo for it) and then npm uninstall -g again
（您可能需要 sudo）然后再次 npm uninstall -g

You're most likely running a file from another install of npm.
您很可能正在运行另一个 npm 安装中的文件。
Run which webpackto see where your shell is finding webpack.
运行which webpack以查看您的 shell 在哪里找到 webpack。
Run npm root -gto find the root of the tree it's supposed to be in, being sure you're running the correct npm with npm -vand which npm.
运行npm root -g以找到它应该在的树的根，确保你正在运行正确的 npmnpm -v和which npm。
If your webpack bin isn't in the npm root, reset your path to the webpack binary e.g. hash -d webpackin bash, and then go remove the unwanted npm root from your PATH variable. You can now use npm install -g webpackand npm uninstall -g webpackand it should work.
如果您的 webpack bin 不在 npm root 中，请重置 webpack 二进制文件的路径，例如hash -d webpack在 bash 中，然后从 PATH 变量中删除不需要的 npm root。您现在可以使用npm install -g webpack和npm uninstall -g webpack它应该工作。

You have to remove the packages manually installed globally on your os with sudo:
您必须使用 sudo 删除在您的操作系统上全局手动安装的软件包：
On OsX navigate to this directory
在 OSX 上导航到此目录
cd /usr/local/lib/node_modules
and
和
sudo rm -rf <packageName> // sudo rm -rf webpack
