Question

当我尝试制作一个新的Rails应用程序时，我在Windows的Rails中不断收到以下错误？安装sqlite3失败。

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

*** 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-opt-include

        --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.

我在计算机上安装了sqlite3，并且我使用的是Windows10。我试图按提示运行的方法运行gem install sqlite3命令，但仍然失败，我该怎么做？

Answer 1

可能您使用了不同的Rails版本。

解决方案是将sqlite的版本更改为1.3.6：

gem 'sqlite3', '~> 1.3.6'

此更改后运行命令：

bundle update

Answer 2

尝试从系统中卸载sqlite3 gem的所有版本，然后仅重新安装版本1.4.0

Answer 3

嗨，当我尝试安装尚未安装MinGW gem的SQLite gem时，我收到了相同的消息

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

安装并重试如果您尚未安装RailsInstaller，而仅安装了Ruby DevKit，它将可以正常工作。如果不是，请先尝试将其卸载，然后删除其余文件夹并通过命令gem install rails

安装rails

Answer 4

试试这个 $ sudo apt-get install libsqlite3-dev 然后， $ bundle install

Gem :: Ext :: BuildError：错误：无法构建gem本机扩展。对于SQlite3
