问题
I created the following file
//npminstall.bat
npm install
echo hello
When I run the following command from Windows 10 Command Line (dos) npminstall.bat, the npm install command fires, but the echo hello doesn't fire. I tried putting a semi-color after the first line like this npm install;, but all that did was give me the help instructions of npm .
How do I get the second line echo hello to fire after the npm install?
Additional Notes
I have found that this also causes the same behaviour:
//npminstall.bat
webpack
echo hello
I think it's because both the npm install command and webpack command takes time to execute, and during that time it doe ssomething I don't expect to the second line.
Followup 2
//npminstall.bat
START /WAIT npm install
echo hello
This seems to almost do what I want to do. Except the npm install command causes a pop up window, and i have to shut down teh pop up window before it continues execution to echo hello world. Can I get rid of the popup window?

When you access another batch file from a batch file, you need to use the CALL command to return control to parent process otherwise control is passed to the batch file being executed.
call npm install
