【Mac】使用brew upgrade 升级 python 后的报错解决

httpie 使用时会显示如下问题：

http GET http://localhost:5000/prosrv/language/published
dyld: Library not loaded: @executable_path/../.Python
  Referenced from: /usr/local/Cellar/httpie/0.9.9_3/libexec/bin/python3.6
  Reason: image not found
[1]    12882 trace trap  http --pretty all GET http://localhost:5000/prosrv/language/published

具体原因是 /usr/local/Cellar/httpie/0.9.9_3/libexec/bin/../.Python 目录无法找到。进入到目录：/usr/local/Cellar/httpie/0.9.9_3/libexec

$ cd /usr/local/Cellar/httpie/0.9.9_3/libexec
$ ls -al
total 16
drwxr-xr-x   7 long  admin  238 12  9  2016 .
drwxr-xr-x  10 long  admin  340  4 13 10:18 ..
lrwxr-xr-x   1 long  admin   70 12  9  2016 .Python -> ../../../../opt/python/Frameworks/Python.framework/Versions/3.6/Python
drwxr-xr-x  18 long  admin  612  4 13 10:18 bin
drwxr-xr-x   3 long  admin  102 12  9  2016 include
drwxr-xr-x   3 long  admin  102 12  9  2016 lib
-rw-r--r--   1 long  admin   60 12  9  2016 pip-selfcheck.json

可以看到 .Python 使用的是 /usr/local/opt/python 目录，由于：【Mac】使用brew upgrade 升级 python 后的报错解决 的原因，/usr/local/opt/python 已经由 python3 变为了Python2，因此 .Python 目录是不存在的。

解决办法

重新链接 .Python 目录：

$ cd /usr/local/Cellar/httpie/0.9.9_3/libexec
$ ln ../../../../opt/python3/Frameworks/Python.framework/Versions/3.6/Python .Python
$ ls -al
total 24
drwxr-xr-x   8 long  admin   272B  4 13 10:46 .
drwxr-xr-x  10 long  admin   340B  4 13 10:18 ..
lrwxr-xr-x   1 long  admin    71B  4 13 10:46 .Python -> ../../../../opt/python3/Frameworks/Python.framework/Versions/3.6/Python
lrwxr-xr-x   1 long  admin    70B 12  9  2016 .Python.bk -> ../../../../opt/python/Frameworks/Python.framework/Versions/3.6/Python
drwxr-xr-x  18 long  admin   612B  4 13 10:18 bin
drwxr-xr-x   3 long  admin   102B 12  9  2016 include
drwxr-xr-x   3 long  admin   102B 12  9  2016 lib
-rw-r--r--   1 long  admin    60B 12  9  2016 pip-selfcheck.json

重新链接后，httpie 就可以正常使用了。
