I am using Windows 10. In CMD, I tried to execute the following mand in my electron project:

setx GH_TOKEN "ghp_B3kYZy7OibM1Rka4Y3jLSiBUlvtSS717FhvE" npm run publish

And I got this error:

ERROR: Invalid syntax. Default option is not allowed more than '2' time(s).
Type "SETX /?" for usage.

The following code is the part of content of the Package.json file:

"scripts": {
    "publish": "electron-builder build -w -p onTagOrDraft"
  }

In the tutorial I am watching, this mand is entered in the Mac operating system as follows, where it works properly:

Use

setx GH_TOKEN "ghp_B3kYZy7OibM1Rka4Y3jLSiBUlvtSS717FhvE" && npm run publish

The && are necessary because there are two mands. Without the &&, the npm run publish will be passed as arguments to SETX

This error also occurs if the environment variable you're setting contains one or more spaces.

In this case, you may avoid the problem by enclosing the value in double quotes. Unlike SET, which would take the quotes to be part of the value, SETX excludes the quotes from your stored value.

The differences in space and quote handling by SET and SETX are shown in the examples below.

For SET with spaces, quotes are not needed (and if included, bee part of the value):

Set a value                              View the value                              
-----------------------------            -----------------------------
C:\TEMP>set MYVAR=some value             C:\TEMP>set MY
                                         MYVAR=some value

C:\TEMP>set MYVAR="some value"           C:\TEMP>set MY
                                         MYVAR="some value"

For SETX with spaces, quotes are needed (and do not bee part of the value):

Set a value                              View the value in a new window                      
-----------------------------            -----------------------------
