解决办法：
One solution was provided here
The idea is to make a static build of curl and then paste it to you /usr/bin/ or /usr/local/bin/. Briefly:
~$ xcode-select --install- Download the latest version of curl.
-
cd to the directory and run
~$ ./configure --disable-shared --with-darwinssl --enable-threaded-resolver~$ make -j `sysctl -n hw.logicalcpu_max`
Copy the compiled curl, which is located in ./src/curl to you /usr/bin/
Note: In the make command in 3, the sign "`" is indeed back quote, not single quote.
