没有这样的文件加载 - bcrypt_ext（via devise） [英] no such file to load -- bcrypt_ext (via devise)

问题描述

我在rails 3上的devise（当前gem）中使用数据库身份验证，当尝试使用username / password登录时，我会收到以下错误。

 不要加载这样的文件 -  bcrypt_ext 
 
加载以下文件时发生此错误：
 bcrypt 
 bcrypt_ext 
  

我以前已经成功安装了bcrypt-ruby-2.1.2gem。

任何想法？我也试图给bundler的git repo地址和提取主，但它不能解决问题。

解决方案

我有这个问题也是。当我安装宝石，输出告诉我

 构建本机扩展。这可能需要一段时间... 
成功安装bcrypt-ruby-3.0.1 
  

所以我假设它实际上已经构建了本地扩展。但是当我在... / gems / bcrypt-ruby-2.1.4 / ext / mri中狩猎时，我发现似乎没有建立任何东西。

我手动进入并运行

  cd [路径到您的宝石文件夹] /gems/bcrypt-ruby-2.1.4/ext/ mri 
 ruby​​ extconf.rb 
 make 
 sudo make install 
  

这对我来说是个窍门。

I'm using database authentication in devise(current gem) on rails 3 and I get the following error when trying to log in with username/password.

no such file to load -- bcrypt_ext 

This error occurred while loading the following files:
   bcrypt
   bcrypt_ext

I have previously "Successfully installed bcrypt-ruby-2.1.2" gem.

Any ideas? I also tried giving bundler the git repo address and fetching the master, but it doesn't solve the issue.

解决方案

I had this problem as well. When I installed the gem, the output told me

Building native extensions.  This could take a while...
Successfully installed bcrypt-ruby-3.0.1

so I assumed that it had, in fact, built native extensions. But when I went hunting in .../gems/bcrypt-ruby-2.1.4/ext/mri I saw that it not appear to have built anything.

I manually went in and ran

cd [path to your gems folder]/gems/bcrypt-ruby-2.1.4/ext/mri
ruby extconf.rb
make
sudo make install

This did the trick for me.
