If you want to run it locally instead of globally, you can run it from your node_modules:
如果你想在本地而不是全局运行它，你可以从你的 node_modules 运行它：
npx nodemon
npx nodemon
回答by Murphy
From you own project.
从你自己的项目。
npx nodemon [your-app.js]
With a local installation, nodemon will not be available in your system path. Instead, the local installation of nodemon can be run by calling it from within an npm script (such as npm start) or using npx nodemon.
对于本地安装，nodemon 在您的系统路径中将不可用。相反，可以通过从 npm 脚本（例如npm start）或使用npx nodemon.
OR
或者
Create a simple symbolik link
创建一个简单的符号链接
ln -s /Users/YourUsername/.npm-global/bin/nodemon /usr/local/bin
ln -s [from: where is you install 'nodemon'] [to: folder where are general module for node]
ln -s [来自：你在哪里安装'nodemon'] [至：节点通用模块所在的文件夹]
node : v12.1.0
节点：v12.1.0
npm : 6.9.0
npm : 6.9.0

I had the same exact problem, expect for Windows OS.
我有同样的问题，期待 Windows 操作系统。
For me, running
对我来说，跑步
npm install -g nodemon --save-dev
npm install -g nodemon --save-dev
(note the -g) worked.
（注意-g）工作。
Maybe somebody else who has this problem on Windows will have the same solution.

I ran into the same problem since I had changed my global path of npm packages before.
我遇到了同样的问题，因为我之前更改了 npm 包的全局路径。
Here's how I fixed it :
这是我修复它的方法：
When I installed nodemon using : npm install nodemon -g --save, my path for the global npm packages was not present in the PATH variable .
当我使用 : 安装 nodemon 时npm install nodemon -g --save，我的全局 npm 包路径不存在于 PATH 变量中。
If you just add it to the $PATH variable it will get fixed.
如果您只是将它添加到 $PATH 变量中，它将得到修复。
Edit the ~/.bashrcfile in your home folder and add this line :-
编辑~/.bashrc主文件夹中的文件并添加以下行：-
export PATH=$PATH:~/npm
Here "npm" is the path to my global npm packages . Replace it with the global path in your system
这里的“npm”是我的全局 npm 包的路径。将其替换为系统中的全局路径

In macOS, I fixed this error by installing nodemon globally
在 macOS 中，我通过全局安装 nodemon 修复了这个错误
npm install -g nodemon --save-dev
and by adding the npm path to the bash_profile file. First, open bash_profile in nano by using the following command,
并通过将 npm 路径添加到 bash_profile 文件。首先，使用以下命令在 nano 中打开 bash_profile，
nano ~/.bash_profile
Second, add the following two lines to the bash_profile file (I use comments "##" which makes it bash_profile more readable)
其次，将以下两行添加到 bash_profile 文件中（我使用注释“##”使其 bash_profile 更具可读性）
## npm
export PATH=$PATH:~/npm
