"pip install mysql-python"安装失败，出现"ld: library not found for -lssl"错误提示。

Question

运行 pip install mysql-python 失败并显示以下错误：

cc -bundle -undefined dynamic_lookup -arch i386 -arch x86_64 -Wl,-F. build/temp.macosx-10.12-intel-2.7/_mysql.o -L/usr/local/Cellar/mysql/5.7.13/lib -lmysqlclient -lssl -lcrypto -o build/lib.macosx-10.12-intel-2.7/_mysql.so
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'cc' failed with exit status 1

我想这可能是一些SSL库没有正确安装。有什么建议吗？

您需要查找您是否拥有openssl库以及它们的位置：

sudo find / -name "openssl"

我在这里找到了它：

ls -lA /usr/local/opt/openssl/

安装Python软件包，您需要使用以下命令：

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install MySQL-python

或者运行 brew info openssl 命令，它会报告："为了让编译器找到这个软件，你可能需要设置： LDFLAGS: -L/usr/local/opt/openssl/lib CPPFLAGS: -I/usr/local/opt/openssl/include" - Carl G
