尽管使用`gem install ...'命令进行安装，但mysql2 gem在捆绑安装中失败. [英] mysql2 gem fails on bundle install, despite installing using `gem install...` command

问题描述

这是我的捆绑安装

Fetching mysql2 0.5.2
Installing mysql2 0.5.2 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

To see why this extension failed to compile, please check the mkmf.log which can be found
here:

/Users/admin/development/locari/vendor/bundle/ruby/2.6.0/extensions/x86_64-darwin-18/2.6.0-static/mysql2-0.5.2/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in
/Users/admin/development/locari/vendor/bundle/ruby/2.6.0/gems/mysql2-0.5.2 for
inspection.

An error occurred while installing mysql2 (0.5.2), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'` succeeds
before bundling.

所以我按照它说的做，然后运行 sudo gem install mysql2 -v'0.5.2'--source

So I do what it says, and run sudo gem install mysql2 -v '0.5.2' --source

$ sudo gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'
Building native extensions. This could take a while...

它安装得很好！但是当我再次运行 bundle install 时，我得到了同样的错误.我尝试在brew中卸载，取消链接并重新安装 mysql .

And it installs fine! But when I run bundle install again, I get the same error. I've tried uninstalling, unlinking, and reinstalling mysql in brew.

接下来我可以尝试什么?

What can I try next??

推荐答案

我找到了答案.我需要先运行这些命令，然后才能运行:

I found the answer. I needed to run these commands first, then it worked:

捆绑配置--local build.mysql2"--with-cppflags = -I/usr/local/opt/openssl/include"

捆绑配置--local build.mysql2"--with-ldflags = -L/usr/local/opt/openssl/lib"

，然后当我运行 bundle install 终于成功了

and then when I ran bundle install it finally worked
