sublime text3为什么不能安装插件

win7（sl2正常运行）下我在PackageControl的debug模式下发现：

Package Control: Trying to execute command /usr/include/curl --user-agent 'Sublime Package Control' --connect-timeout 30 -sSL --compressed --dump-header /tmp/tmptv5Nt1 --cacert '/home/leo/.config/sublime-text-2/Packages/Package Control/certs/ca-bundle.crt' -v https://sublime.wbond.net/repositories.json
用的是curl，作者的原话是“Because ST2 does not include the ssl module on Linux and thus urllib can't be used for HTTPS downloads.”
所以我自己改了 package control.py 把/usr/include/curl 改为了/usr/bin/curl 然后就居然成功了。
https://github.com/wbond/sublime_package_control/issues/484 这个是我提的issues
总之我是这么解决的，sl3可能不一样，不过多看下debug信息总能发现点什么。
