Brew：没有空间了

Question

我正在尝试安装phantojs并且brew说设备上没有剩余空间：

brew  -v  install phantomjs
==> Cloning https://github.com/Vitallium/phantomjs.git
Updating /home/user/.cache/Homebrew/phantomjs--git
git config remote.origin.url https://github.com/Vitallium/phantomjs.git
git config remote.origin.fetch +refs/tags/2.0.1:refs/tags/2.0.1
==> Checking out tag 2.0.1
git checkout -f 2.0.1 --
HEAD is now at 33aaaff... Sync QtBase
git reset --hard 2.0.1
HEAD is now at 33aaaff Sync QtBase
git submodule foreach --recursive git submodule sync
Entering 'src/qt/3rdparty'
Entering 'src/qt/qtbase'
Entering 'src/qt/qtwebkit'
git submodule update --init --recursive
Error: No space left on device - write

虽然：

df -kh
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        19G   17G  535M  97% /

/dev/sda3       433G   91G  320G  23% /home

安装是否需要超过500 Mb？

编辑： 在评论之后，这是inode信息：
