问题发生：
在clone github 上的代码时，
git clone https://github.com/wongdean/rime-settings.git
发现进度会卡住不动，
Administrator@philonic MINGW64 /g/software
$ git clone https://github.com/wongdean/rime-settings.git
Cloning into 'rime-settings'...
remote: Enumerating objects: 539, done.
Receiving objects: 36% (195/539), 50.43 MiB | 730.00 KiB/s
过几分钟就报错。
error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
然后，没有关注错误，继续 git clone, 又报其他错误了。
Administrator@philonic MINGW64 /g/software
$ git clone https://github.com/wongdean/rime-settings.git
Cloning into 'rime-settings'...
remote: Enumerating objects: 539, done.
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
网上搜了一下，也尝试了一些，最终下面的语句解决
git config --global core.compression 0 //关闭压缩
继续 git clone ， 这次报错和第一次一样了，说明根本问题还没有解决。
Administrator@philonic MINGW64 /g/software
$ git clone https://github.com/wongdean/rime-settings.git
Cloning into 'rime-settings'...
remote: Enumerating objects: 539, done.
error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
这个报错，网上的解法很统一。
git config --global http.postBuffer 524288000
继续 git clone， 这次终于成功了。
Administrator@philonic MINGW64 /g/software
$ git clone https://github.com/wongdean/rime-settings.git
Cloning into 'rime-settings'...
remote: Enumerating objects: 539, done.

遇到问题莫方，遇到一个解决一个。方法总比问题多。
