几个月来，我一直在使用 mongodb cookbook 成功创建用户帐户，但最近发生了一些变化，我不知道是什么原因。默认配方无错误完成，mongodb 服务器安装成功，但是 user_management 配方失败并出现错误NameError: uninitialized constant Mongo::MongoClient。
这是在 AWS Opsworks 环境中，其中 chef 版本为 11.10，Berkshelf 版本为 3.2.0。

cookbook 'mongodb', '~> 0.16.1', github: 'edelight/chef-mongodb'
下面是我在该层中使用的自定义 json 的 mongodb 部分：
"mongodb": {
"dbconfig_file": "/etc/mongod.conf",
"sysconfig_file": "/etc/default/mongod",
"default_init_name": "mongod",
"instance_name": "mongod",
"admin": {
"username": "admin",
"password": "xxxxx"
},
"config": {
"auth": true,
"bind_ip": "0.0.0.0",
"port": "27017",
"logpath": "/var/log/mongo/mongod.log",
"dbpath": "/var/lib/mongo"
},
"authentication": {
"username": "admin",
"password": "xxxxx"
},
"users": [
{
"username": "mongodb-dba1",
"password": "xxxxx",
"roles": [
"root"
],
"database": "admin"
},
{
"username": "mongodb-rw1",
"password": "xxxxx",
"roles": [
"readWrite"
],
"database": "apis_cache"
},
{
"username": "mongodb-r1",
"password": "xxxxx",
"roles": [
"read"

"database": "apis_cache"
},
{
"username": "admin",
"password": "xxxxx",
"roles": [
"userAdminAnyDatabase",
"dbAdminAnyDatabase"
],
"database": "admin"
}
]
},
这是我执行 mongodb::user_management 配方时的 opsworks 日志。

当我将 chef.io cookbook 的最新提交更新为“悲观地允许 1.X mongo gem”时，我得到了同样的错误：

感谢您的帮助！
答案1
根据我在拉取请求中看到的修改384我修改了食谱，将“mongo”和“bson_ext”版本锁定为 1.x，这为我解决了问题（悲观地说，允许 1.x 不起作用）。
属性/默认.rb
# install the mongo and bson_ext ruby gems at compile time to make them globally available
# TODO: remove bson_ext once mongo gem supports bson >= 2
default['mongodb']['ruby_gems'] = {
- :mongo => nil,
- :bson_ext => nil
+ :mongo => '1.12',
+ :bson_ext => '1.12'
}
食谱/用户管理.rb
-chef_gem 'mongo'
+include_recipe 'mongodb::mongo_gem'
users = []
admin = node['mongodb']['admin']
修改后的食谱现已可用这里。请注意，由于宝石被锁定在特定版本，因此这不是永久的修复。
希望官方食谱的维护者能花一些时间来处理所有积压的 PR。
更新（2015 年 10 月 5 日）：chef-brigade 勇敢地接手了这本食谱的维护工作，并开始处理 PR 积压问题。您可以从厨师大队回購。
