Command to remove all npm modules globally?
提问by EhevuTov
Is there a command to remove all global npm modules? If not, what do you suggest?
是否有删除所有全局 npm 模块的命令？如果没有，你有什么建议？

The following command removes all global npm modules. Note: this does not work on Windows. For a working Windows version, see Ollie Bennett's Answer.
以下命令删除所有全局 npm 模块。注意：这不适用于 Windows。对于可用的 Windows 版本，请参阅Ollie Bennett 的回答。
npm ls -gp --depth=0 | awk -F/ '/node_modules/ && !/\/npm$/ {print $NF}' | xargs npm -g rm
Here is how it works:
下面是它的工作原理：
npm ls -gp --depth=0lists all global top level modules (see the cli documentation for ls)awk -F/ '/node_modules/ && !/\/npm$/ {print $NF}'prints all modules that are not actually npm itself (does not end with/npm)xargs npm -g rmremoves all modules globally that come over the previous pipe

For those using Windows, the easiest way to remove all globally installed npm packages is to delete the contents of:
对于使用Windows 的用户，删除所有全局安装的 npm 包的最简单方法是删除以下内容：
C:\Users\username\AppData\Roaming\npm
C:\Users\username\AppData\Roaming\npm
You can get there quickly by typing %appdata%/npmin either the explorer, run prompt, or from the start menu.
您可以通过%appdata%/npm在资源管理器、运行提示或从开始菜单中键入来快速到达那里。

I tried Kai Sternad's solutionbut it seemed imperfect to me. There was a lot of special symbols left after the last awkfrom the deps tree itself.
我尝试了Kai Sternad的解决方案，但对我来说似乎不完美。awk在 deps 树本身的最后一个之后留下了很多特殊符号。
So, I came up with my own modification of Kai Sternad's solution (with a little help from cashmere's idea):
因此，我想出了自己对Kai Sternad解决方案的修改（在Cashmere 的想法中有一点帮助）：
npm ls -gp --depth=0 | awk -F/node_modules/ '{print }' | grep -vE '^(npm|)$' | xargs -r npm -g rm
npm ls -gp --depth=0lists all globally-installed npm modules in parsableformat:
npm ls -gp --depth=0以可解析的格式列出所有全局安装的 npm 模块：
/home/leonid/local/lib
/home/leonid/local/lib/node_modules/bower
/home/leonid/local/lib/node_modules/coffee-script
...
awk -F/node_modules/ '{print $2}'extracts module names from paths, forming the list of all globally-installed modules.
awk -F/node_modules/ '{print $2}'从路径中提取模块名称，形成所有全局安装模块的列表。
grep -vE '^(npm|)$'removes npm itself and blank lines.
grep -vE '^(npm|)$'删除 npm 本身和空行。
xargs -r npm -g rmcalls npm -g rmfor each module in the list.
xargs -r npm -g rm调用npm -g rm列表中的每个模块。
Like Kai Sternad's solution, it'll only work under *nix.
就像Kai Sternad的解决方案一样，它只能在 *nix 下工作。

sudo npm list -g --depth=0. | awk -F ' ' '{print }' | awk -F '@' '{print }' | sudo xargs npm remove -g
worked for me
对我来说有效
sudo npm list -g --depth=0.lists all top level installedawk -F ' ' '{print $2}'gets rid of ├──awk -F '@' '{print $1}'gets the part before '@'sudo xargs npm remove -gremoves the package globally
sudo npm list -g --depth=0.列出所有顶级安装awk -F ' ' '{print $2}'去掉 ├──awk -F '@' '{print $1}'获取 '@' 之前的部分sudo xargs npm remove -g全局删除包

For those using Powershell:
对于那些使用Powershell 的人：
npm -gp ls --depth=0 | ForEach-Object { Get-Item $_ } | Where { $_.Name -ne 'npm' } | ForEach-Object { npm rm -g $_.Name }
To clear the cache:
要清除缓存：
npm cache clear

Just switch into your %appdata%/npmdirectory and run the following...
只需切换到您的%appdata%/npm目录并运行以下命令...
for package in `ls node_modules`; do npm uninstall $package; done;
EDIT: This command breaks with npm 3.3.6 (Node 5.0). I'm now using the following Bash command, which I've mapped to npm_uninstall_all in my .bashrc file:
编辑：此命令与 npm 3.3.6（节点 5.0）中断。我现在正在使用以下 Bash 命令，该命令已映射到我的 .bashrc 文件中的 npm_uninstall_all：
npm uninstall `ls -1 node_modules | tr '/\n' ' '`

If you would like to remove all the packages that you have installed, you can use the npm -g lscommand to find them, and then npm -g rmto remove them.
如果要删除所有已安装的软件包，可以使用该npm -g ls命令查找它们，然后npm -g rm将其删除。

OS not specified by OP. For Windows, this script can be used to nuke the local and the user's global modules and cache.
OP 未指定操作系统。对于Windows，此脚本可用于破坏本地和用户的全局模块和缓存。
I noticed on linuxthat the global root is truly global to the system instead of the given user. So deleting the global root might not be a good idea for a shared system. That aside, I can port the script to bashif interested.
我注意到在linux上，全局根目录对于系统来说是真正全局的，而不是给定的用户。因此，对于共享系统，删除全局根目录可能不是一个好主意。除此之外，如果有兴趣，我可以将脚本移植到bash。
For Windows, save to a cmd file to run.
对于Windows，保存到 cmd 文件以运行。
