(Updated: )

1

But you may get an error like below:

myusername@c126h060:~$ brew link node
Linking /usr/local/Cellar/node/0.12.6... 
Error: Could not symlink share/systemtap/tapset/node.stp
Target /usr/local/share/systemtap/tapset/node.stp
already exists. You may want to remove it:
  rm '/usr/local/share/systemtap/tapset/node.stp'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

To list all files that would be deleted:
  brew link --overwrite --dry-run node

That’s because you don’t have the writable permission of the path /usr/local/share/systemtap, you can use the below command to permit it.

1
chown -R <yourusername>:<yourgroupname> systemtap

If you don’t know the yourusername, you can use the command whoami to get it. The yourgroupname is usually staff.

Install hexo to deploy my blog

Clone the blog repository

1
git clone --recurse-submodules https://github.com/SSBun/blog.git

The option --recurse-submodules is used to clone the blog’s theme repository. You can find the file .gitmodules in the blog directory. It’s used to manage the submodules for the main git repository.

If you forget to add the option --recursive-submodules when cloning the repository, you can run the two commands to fix it.

The first:

1
git submodule init

The seconds:

1
git pull --recurse-submodules
