所以当我收到此错误时,我试图在我新创建的Rails应用程序中运行bundle install
:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing sqlite3 (1.3.10), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.10'` succeeds before bundling.
我目前的sqlite3版本:
3.8.7.4 2014-12-09 01:34:36 f66f7a17b78ba617acde90fc810107f34f1a1f2e
Ruby:
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]
酿酒:
0.9.5
更多信息:
$ which sqlite3
/usr/local/bin/sqlite3
$ whereis sqlite3
/usr/bin/sqlite3
这与Ruby 2.0的冲突和OS X附带的默认Ruby 1.8有什么关系吗?我正在使用OS X 10.10。
我该如何解决这个问题?非常感谢你!

检查你的sqlite的安装位置并运行以下命令(我假设/ opt / local here)
gem install sqlite3 -- --with-sqlite3-dir=/opt/local
然后
bundle install

所以我找到了解决方案:只需(手动)卸载计算机中任何现有版本的sqlite3。我做的是:
which -a sqlite3
找出安装sqlite3的目录(对我来说有4个版本的O.o)。删除所有这些sqlite3文件(通过rm)/usr/local/lib
,usr/local/bin
和usr/local/include
删除所有内容后,再次在app dir中运行bundle install
,将自动安装所需的sqlite3版本。
$bundle install

尝试在您的控制台中安装这些内容:
安装brew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)""
# Add Homebrews binary path to the front of the $PATH
echo 'export PATH=/usr/local/bin:$PATH' >> ~/.bash_profile
source ~/.bash_profile
brew install sqlite3
brew install libsqlite3-dev
bundle install

我只是添加自己的解决方案,以供其他人尝试,以防上述情况对他们不利。
我不得不冲泡卸载sqlite3,然后不得不从rails应用目录中删除sqlite3s。
使用sudo rm -fr {app_route}/vendor/bundle/ruby/2.3.0/gems/sqlite3-1.3.13/
然后使用bundle install
重新安装sqlite3。

这在 #include <iostream>
const int f1(int a)
{
return 15;
}
const int& f2(int a)
{
return 14;
}
int& f3(int a)
{
a = 12;
return a;
}
int main()
{
auto a{ 10 };
auto b = f1(a);
auto c = f2(a);
auto d = f3(a);
std::cout << a << " " << b << " " << c << " " << d << std::endl;
a = 1;
b = 2;
c = 3;
d = 4;
std::cout << a << " " << b << " " << c << " " << d << std::endl;
}
关于 debian 风格的上下文中对我有用:
Dockerfile
.. 成功了!

当您尝试创建新项目时,rails会尝试使用最新版本的rails创建。因此,bundle install引发了一些错误。
创建新项目时,您可以指定已安装到OS X的rails的版本,如下所示。
$ rails -v
Rails 4.x.x
之后,您可以创建如下的新项目。
$ rails _4.x.x_ new PROJECT_NAME
