显示资源库~/Library文件夹

打开Finder，先按shift-command-H，再按command-J，在弹窗口中选取“显示资源库文件夹”1。

Bash profile 设置

Mac OS的 默认PATH为/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin2。我们想让Homebrew安装的软件优先级大于系统默认安装的软件（如Python）。在Terminal打开：

1
vim ~/.bash_profile

并且添加：

1
2
3
4
5
6
# Set architecture flags
export ARCHFLAGS="-arch x86_64"
# Ensure user-installed binaries take precedence
export PATH=/usr/local/bin:$PATH
# Load .bashrc if it exists
test -f ~/.bashrc && source ~/.bashrc

第一句的作用是让编译器知道系统是64位的。然后执行下面一句让配置生效：

1
source ~/.bash_profile

安装proxychains-ng

在使用brew update时，发现速度十分慢，于是可以尝试使用ProxyChains-NG3，官方说明:

proxychains ng (new generation) - a preloader which hooks calls to sockets in dynamically linked programs and redirects it through one or more socks/http proxies. continuation of the unmaintained proxychains project.

使用Homebrew安装（如果是10.11，要先关闭SIP），并配置:

1
2
brew install proxychains-n
vim /usr/local/etc/proxychains.conf

在末尾，删掉socks4的那一条目（重要），并且根据实际添加代理：

1
socks5  127.0.0.1 1080

然后就可以通过在命令面前添加proxychains4使用代理了，如：

1
2
proxychains4 brew update
proxychains4 brew upgrade

安装编译

Let's call this directory 'source_dir' (where this INSTALL file is). Before starting, create another directory which we will call 'build_dir'.

Do:

1
2
3
cd build_dir
cmake source_dir
make install

The "make install" step may require administrator privileges.

You can adjust the installation destination (the "prefix") by passing the -DCMAKE_INSTALL_PREFIX=myprefix option to cmake, as is explained in the message that cmake prints at the end.

删除

If you have a manifest file which lists all the files that were installed with make install you can run this command which I have from another answer:

1
cat install_manifest.txt | xargs echo rm | sh

If you have sudo make install you will need to add a sudo to your uninstall:

1
cat install_manifest.txt | xargs echo sudo rm | sh
