as for me, this problem about the PATH. because the sh can't find the script in specifed PATHS.
至于我，这个关于 PATH 的问题。因为 sh 在指定的 PATHS 中找不到脚本。
you should add the npm global script path to your PATH variable.
您应该将 npm 全局脚本路径添加到您的 PATH 变量中。
if you are using "Git Bash", run the below command.
如果您使用的是“Git Bash”，请运行以下命令。
PATH=$PATH:/c/Users/CHANGE_WITH_YOUR_USERNAME/AppData/Roaming/npm
notice that, this is temporary. when you close the git bash, the PATH variable will be deleted.
请注意，这是暂时的。当您关闭 git bash 时，PATH 变量将被删除。
for the permanently, you have to create a .bashrc file in your home folder.
对于永久，您必须在您的主文件夹中创建一个 .bashrc 文件。
run these commands on your git bash.
在你的 git bash 上运行这些命令。
cd ~
echo PATH=$PATH:/c/Users/CHANGE_WITH_YOUR_USERNAME/AppData/Roaming/npm >> .bashrc

@alioygur : Is Exactly Right about the solution.
@alioygur ：解决方案完全正确。
But a simple the issue is the installed npm plugin path is not added in the SYSTEM ENVIRONMENT VARIABLE PATH. you had to do that manually.
但一个简单的问题是已安装的 npm 插件路径未添加到SYSTEM ENVIRONMENT VARIABLE PATH 中。您必须手动执行此操作。
now the question comes what is the path address to put in?
现在问题来了，要输入的路径地址是什么？
ANSWER : The path of the installed npm plugin generally goes inside the nodejs installation folder >> nodejs\node_modules\npm\bin

Sometimes npm plugin also resides inside the temporary APP DATA.(As said by @alioygur)
有时 npm 插件也驻留在临时 APP DATA 中。（如@alioygur 所说）
C:\Users\*USERNAME*\AppData\Roaming\npm
