Question

我正在尝试使用bcrypt来保护用户密码，但是当我在数据库中创建新用户时，我收到此错误：“LoadError：无法加载此类文件 - bcrypt”

到目前为止我做了什么：

我在Gemfile中放置了一个gem sudo bundler install
我安装了它 $ gem list bcrypt *** LOCAL GEMS *** bcrypt (3.1.11)
bcrypt在宝石列表中

$ rails console 
Running via Spring preloader in process 21100
Loading development environment (Rails 5.1.0)
irb(main):001:0> User.create(username: "user1" , password: "pass123", password_confirmation: "pass123")
You don't have bcrypt installed in your application. Please add it to your Gemfile and run bundle install
LoadError: cannot load such file -- bcrypt
        from app/models/user.rb:2:in `<class:User>'
        from app/models/user.rb:1:in `<top (required)>'
        from (irb):1

我已重新启动服务器

sudo service apache2 restart

我在rails console中添加了新用户

bcrypt-ruby

正如你所看到的那样无效！

我尝试再次卸载并安装bcrypt =＆gt;相同的结果
我尝试过其他版本的bcrypt =＆gt;相同的结果
我将install bcrypt --platform=ruby添加到gems =＆gt;相同的结果
我使用了gem gem 'bcrypt-ruby', '3.1.5', :require => 'bcrypt'和cd [path to gems folder]/gems/bcrypt-ruby-2.1.4/ext/mri ruby extconf.rb make sudo make install =＆GT;相同的结果
我更新了所有gems =＆gt;相同的结果
我手动构建了本机扩展程序

public class UEC extends AppCompatActivity {

List<SavePlace> userInfo;

String name;
boolean flag;
SharedPreferences sharedPref;

public UEC(SharedPreferences sharedPref){
    this.sharedPref = sharedPref;
}

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

public boolean checkIfUserExists() {

    email = sharedPref.getString("userEmail", "");

    Retrofit retrofitCheckUser = ApiClientSavePlace.getClient();
    ApiInterfaceSavePlace apiInterfaceSavePlace = retrofitCheckUser.create(ApiInterfaceSavePlace.class);
    final Call<List<SavePlace>> checkUser = apiInterfaceSavePlace.getSavePlaces();

    checkUser.enqueue(new Callback<List<SavePlace>>() {
        @Override
        public void onResponse(Call<List<SavePlace>> call, Response<List<SavePlace>> response) {
            userInfo = response.body();
            try {
                if(userInfo.size()!=0){
                    for (int i = 0; i <= userInfo.size(); i++) {
                        String emailReturned = userInfo.get(i).getEmail();
                        Log.d("response", "email returned: " + emailReturned);
                        Log.d("sharedpref", "email: " + email);
                        if (emailReturned.equals(email)) {
                        Log.d("response:", "email match?: " + emailReturned.equals(email));
                            flag = true;
                            SharedPreferences.Editor editor = sharedPref.edit();
                            editor.putInt("userID", userInfo.get(i).getId());
                            Log.d("ID returned", String.valueOf(userInfo.get(i).getId()));
                            editor.apply();
                            break;
                        }
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Call<List<SavePlace>> call, Throwable throwable) {
            Log.d("RESPONSE", "FAILED CHECKING USER ID/SOMETHING HAPPENED");
        }
    });
    return flag;
}

}

=＆GT;相同的结果

我解决了这个问题。我差不多2天都在寻找它！

使用pkill命令使用name spring终止所有进程，如下所示：

  $ pkill -15 -f spring

打开一个新终端并：捆绑执行警卫它给你错误“bundler：command not found：guard”别担心。请确保您已gem list bcrypt安装了bycrypt 安装捆绑包

sudo bundle install

然后重启服务器

sudo service apache2 restart

现在有效！
