I am using mongoid in my Rails project. Installing the bson_ext gem, it gives me the above error.
Can anybody tell me what is the problem?
回答1:
Not sure why your make is not using the correct install. But it's easy to do a quick fix:
sudo ln -s /usr/bin/install /bin/install
This will link the existing install into /bin and should enable make to continue.
