MacOS安装报错 ld: library not found for -lssl解决方案

Macos安装报错 ld: library not found for -lssl


首先,我通过:

pip install mysqlclient==1.3.13

然后报错

ld: library not found for -lssl

其中,主要报错:

ld: library not found for -lssl

原因分析:

安装过程中,无法找到openssl文件

由于苹果公司已经放弃openssl加密转而使用自家的加密方式,导致mac上面是没有oepnssl的,所以需要

# 安装openssl
brew install openssl
# 如果已经安装
brew upgrade openssl
# 如果还不行
xcode-select --install

如果还不行(例如我),那么直接在pip的时候链接brew的openssl,记得用上不使用缓存模式

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip --no-cache install mysqlclient==1.3.13

ok!

结果如下:

 env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip --no-cache install mysqlclient==1.3.13

这些是我搜集git issue和栈溢上整合出来的解决方案,如果其他更好的解决方法,欢迎留言…
