Gem::Ext::BuildError: 错误:无法构建 gem 本机扩展.对于 SQLite3 [英] Gem::Ext::BuildError: ERROR: Failed to build gem native extension. for SQlite3

问题描述

当我尝试制作新的 rails 应用程序时，我在 windows 上的 rails 中不断收到以下错误?安装 sqlite3 时失败.

I keep getting the below error in rails on windows when I try to make a new rails app? It fails when it gets to installing sqlite3.

current directory:
C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/sqlite3-1.4.0/ext/sqlite3
C:/Ruby25-x64/bin/ruby.exe -r ./siteconf20190220-14164-174xy0j.rb extconf.rb
checking for sqlite3.h... yes
checking for pthread_create() in -lpthread... yes
checking for -ldl... no
checking for dlopen()... no
missing function dlopen
*** extconf.rb failed ***
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.
Provided configuration options:
        --with-opt-dir
        --without-opt-dir

        --with-pthreadlib
        --without-pthreadlib
        --with-dllib
        --without-dllib

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

C:/Ruby25-x64/lib/ruby/gems/2.5.0/extensions/x64-mingw32/2.5.0/sqlite3-1.4.0/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in
C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/sqlite3-1.4.0 for inspection.
Results logged to
C:/Ruby25-x64/lib/ruby/gems/2.5.0/extensions/x64-mingw32/2.5.0/sqlite3-1.4.0/gem_make.out

An error occurred while installing sqlite3 (1.4.0), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.4.0' --source 'https://rubygems.org/'`
succeeds before bundling.

我的机器上安装了 sqlite3 并且我使用的是 Windows 10.我尝试过运行 gem install sqlite3 命令，就像它提示我的那样，但它仍然失败，我做错了什么?

I have sqlite3 installed on my machine and I am using windows 10. I have attempted ot run the gem install sqlite3 command like it prompts me to but it still fails what am I doing wrong?

推荐答案

我在未安装 MinGW gem 的情况下尝试安装 SQLite gem 时收到相同的消息

Hi I got the same message when tried to install SQLite gem without MinGW gem installed already

C:\Sites>ridk exec pacman -S mingw-w64-x86_64-dlfcn

安装并重试如果您没有只安装 RailsInstaller Ruby DevKit，它应该可以工作.如果没有，请先尝试卸载它，删除剩余的文件夹并通过命令 gem install rails

Install it and try again If you DON'T have installed RailsInstaller only Ruby DevKit it should work. If not please try uninstalling it first, removing the remaining folders and installing rails by command gem install rails
