Troubleshoot Mac installation M2crypto prompt Unable to find OpenSSL header file issues

That's probably the problem.

Since OS X is not even/usr/include after the upgrade, use the command

? xcode-select--install?

Install the Xcode command-line tool and/usr/include will come back several times.

But there's no OpenSSL in there.

When installing OpenSSL in addition, you will find that there is no head file ln to/usr/include, no eggs,/usr/include or a system directory that cannot be changed.

But do we notice the installation? M2crypto when the error is prompted SWIG statement there is a problem, so you can modify the Swig address path, as follows, duly:

sudo env ldflags= "-l$ (Brew--prefix OpenSSL)/lib" \

Cflags= "-i$ (Brew--prefix OpenSSL)/include" \

Swig_features= "-cpperraswarn-includeall-i$ (Brew--prefix OpenSSL)/include" \

Pip Install M2crypto

Pro-Test success
