每当gem'无法加载命令时:rake'

Question

寻求一些帮助.

我正在使用whenevergem(v0.9.7)和rake(v11.2.2)运行rails app (v3.2.5).我也在一个docker容器映像中执行此操作ruby:2.3(cron已安装并bundle install已运行)

这是我的 schedule.rb

set :environment, ENV['RAILS_ENV']

every '*/2 9,10,11,12,13,14,15,16 * * 1-5' do
    rake "import_csv", output: {:error => 'log/import_csv_errors.log', :standard => 'log/import_csv.log'}'
end

note RAILS_ENV设置在容器启动时development

这是我在build(crontab -l)后面的容器上的cron作业:

# Begin Whenever generated tasks for: /usr/src/app/config/schedule.rb
*/2 9,10,11,12,13,14,15,16 * * 1-5 /bin/bash -l -c 'cd /usr/src/app && RAILS_ENV=development bundle exec rake import_csv --silent >> log/import_csv.log 2>> log/import_csv_errors.log'

# End Whenever generated tasks for: /usr/src/app/config/schedule.rb

当此cron作业运行时,日志返回:

import_csv_errors.log

import_csv.log

bundler: failed to load command: rake (/usr/local/bin/rake)

现在这是奇怪的事情.如果我复制cron job命令:

/bin/bash -l -c 'cd /usr/src/app && RAILS_ENV=development bundle exec rake import_csv --silent >> log/import_csv.log 2>> log/import_csv_errors.log'

并在容器中运行它,它工作正常,但如果cron作业运行它,我在日志中得到错误!我迷失在这里......

我试过添加

env :PATH, ENV['PATH']
env :GEM_PATH, '/usr/local/bundle'

到顶部,schedule.rb我试着做

command 'cd /usr/src/app && RAILS_ENV=development bundle exec rake import_csv --silent >> log/import_csv.log 2>> log/import_csv_errors.log'

而不是rake在任务中使用,我得到相同的错误..

任何帮助都是适当的

Answer 1

我通过修改修复了相同的错误Dockerfile:

RUN gem update --system 2.6.12
RUN gem install bundler --version 1.14.6

而且schedue.rb:

ENV.each { |k, v| env(k, v) }

Answer 2

我已经更新了我的 rake 版本，它对我有用。以下是我遵循的步骤：

sudo bundle update rake
sudo bundle install

打开 Rakefile 并将该行替换rake/rdoctask为require 'rdoc/task'.
