回答1:

If you want to install this specific version of the angular cli you have to use this command:

npm install -g @angular/cli@1.4.9

Perhaps you have an other version currently installed on your system you should read this also.

回答2:

The version of angular used in a project is determined by the version of angular cli installed. any specific version of angular cli can be installed with the following command:

npm install --global @angular/cli@x.x.x.

example:

npm install --global @angular/cli@1.6.6

even if you have another version of angular cli (either newer or older) installed. That won't cause issues.
