Squarespace server not running

Whenever I try to run the server, end up having the issue below. I have already tried to modify the referred file with no success and currently have the version 1.7.0. Any help would be much appreciated.

```

At C:\Program Files\nodejs\squarespace
-server.ps1:12 char:29
+   & "$basedir/echo$exe" off & "$base
dir/node_modules/@squarespace/ser ...  
+                             ~

allowed. The & operator is reserved    
for future use; wrap an ampersand in   
double quotation marks ("&") to pass   
it as part of a string.
