Question

我有一台新机器，并重新安装了rbenv（我以前一直使用rvm）。 This gem现在不会加载到我的应用中。我没有更改代码。现在和那时之间的唯一区别是rbenv。

Loading development environment (Rails 5.2.1)
irb(main):001:0> SportsApi::Fetcher::Score::NBA
Traceback (most recent call last):
        1: from (irb):1
NameError (uninitialized constant SportsApi::Fetcher)

有趣的是，如果我将gem克隆到本地计算机，然后更改Gemfile中的路径，则它确实可以加载/工作。

# gem 'sports_api', git: 'git@github.com:mikesilvis/sports_api.git'
gem 'sports_api', path: '~/dev/sports_api'


irb(main):001:0> SportsApi::Fetcher::Score::NBA
=> SportsApi::Fetcher::Score::NBA

为什么它不能在本地路径上工作，而不能在git路径上工作？关于如何解决此问题（使用git路径）的任何想法？预先谢谢你。

编辑：这是完整的回溯。

uninitialized constant SportsApi::Fetcher

Answer 1

已更新：

sports_api是宝石之旅。

在lib/sports_api.rb的第一行： reject { |file| file.match(/version/) }块将过滤所有红宝石文件。由于rbenv将ruby安装到~/.rbenv/versions目录中，因此每个gem文件的路径都将带有version字符串：

每个Ruby版本都安装在~/.rbenv/versions下的自己的目录中。

旧答案：

在reject第一行中删除sports_api.rb方法：

Dir["#{File.dirname(__FILE__)}/sports_api/**/**/*.rb"].sort_by(&:length).reject { |file| file.match(/version/) }.each { |f| load(f) }

收件人：

Dir["#{File.dirname(__FILE__)}/sports_api/**/**/*.rb"].sort_by(&:length).each { |f| load(f) }

然后，您应该删除捆绑程序安装的缓存的gem文件并运行bundle install

Answer 2

运行rbenv init并按照说明进行操作。请注意，安装rbenv后需要重启终端（有关详细信息，请参见https://github.com/rbenv/rbenv#installation）。

通过执行bundle show sports_api，确保在rbenv路径中安装了gem。

Answer 3

我看到与asdf（vs rbenv）相同的行为，所以这不是rbenv问题。

在调用代码之前，在代码库中的某个位置添加require 'sports_api'，同时使用您希望使用的语法，将解决加载问题。

我不确定100％的根本原因，但我怀疑这可能是路径/ git语法处理方式的组合。使用路径语法似乎会自动为您提供代码（我不希望如此）

Answer 4

我在其他宝石上遇到了同样的问题，并通过重新启动spring解决了这个问题：

bin/spring stop

spring有助于更快地加载环境，但有时会遇到缓存问题。

宝石未加载：NameError（未初始化的常量）但是宝石在当地道路上工作
