运行rake db：migrate后出现以下错误

rake aborted!

libssl指的是什么？

Answer 1

首先卸载mysql2 gem：

gem uninstall mysql2

确保已安装openssl：

brew install openssl

它将打印一些注释。我们对此部分感兴趣：

For compilers to find this software you may need to set:
LDFLAGS:  -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

然后您可以像这样重新安装mysql2 gem：

gem install mysql2 -v 0.4.10 -- --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib

你应该很好。

Answer 2

以下修复解决了问题

   ==> cd /usr/local/Cellar/openssl/1.0.2s/lib/

==> sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/local/lib

Answer 3

因此，我自己的问题的答案如下：在5个以上stackoverflow解决方案中，这是唯一可行的解决方案：

brew install openssl

cd /usr/local/Cellar/openssl/1.0.1f/lib

sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/lib/

Answer 4

就我而言，只是卸载并安装mysql2 gem可以达到目的

"value"

$ gem uninstall mysql2

Answer 5

仅一个命令：

gem pristine mysql2

然后我解决此问题

Answer 6

对于import pandas as pd df = pd.DataFrame({ 'A': ["x", "x", "y", "y"], 'B': [1, 2, 1, 1], }) df.drop_duplicates(subset=['A', 'B'], keep=False).drop_duplicates(subset=['A'])['A']的用户：

rbenv

rake db：mysql2 gem发生迁移错误-库未加载：libssl.1.0.0.dylib
