没关系，Jay，我很高兴有人能稍微扶我一把 
我唯一担心的是，我所做的更改会导致所有附件都未上传，但却被标记为迁移完成，这样我就不得不重新开始。
您是否知道 Discourse 中的 short_url 属性具体用于什么？我可以随心所欲地更改它，还是必须匹配对象才能在后续的帖子和附件绑定步骤中使用？

short_url 是 Upload 模型中的一个函数。如果它不起作用，那是因为没有 Upload。我猜接下来我会看看 upload 是否是从 find_upload 返回的。也许它实际上并没有找到它。

输出如下：
我更改了标识性数据（文件名和 S3 存储桶 URL）
#418 可以正常工作，#419 不可以，除了属性数据不同之外，它看起来没问题，对吗？
419 中的文件名使用了下划线，而 418 没有，但之前也有其他文件名使用了下划线，并且工作正常。
其他文件名也比失败的那个长得多，所以我认为这与文件名无关。

上面的帖子有误，@pfaffman 的假设是正确的。
由于我添加了自己的逻辑，脚本在我自己的代码上崩溃了，因此显示的最后一项是最后成功的项。
问题项除了文件名外，所有属性都设置为 nil。
检查 sha1 属性是否为 nil 即可解决问题。
非常感谢 @pfaffman <3

抱歉又来打扰你了，pfaffman，但这是正常的吗？
3679343 / 3550728 (103.6%)
在上传附件时，似乎超过了 100%？

这意味着获取附件总数的查询与获取附件的查询是不同的。这可能意味着附件的数量是错误的。除非它会一直持续下去，那样的话，就有问题了。

Attempted @Jack51 s Excelent recap for the steps involved.
However (attempting this on a digitalocean environment) the step for mariadb fails… following those instructions (with 10.5 instead of 10.3) the mysql service is unknown after install.
likely has something to do with that apt-utils wasn’t installed maybe… but also throws
invoke-rc.d: policy-rc.d denied execution of restart.
not sure how to proceed
edit: rebuilt the discourse, made sure to install apt-utils first… still get the same error… can’t start the mariadb server
# apt-get update && apt-get install mariadb-server mariadb-client libmariadbd-dev

好的……我让导入脚本运行了，尽管在导入用户时出现了一个错误。
有什么办法可以解决这个问题吗？

更新：已找出问题所在。
由于 Discourse 现在需要 TZInfo 2.x，迁移脚本目前已损坏，因为它使用了 TZInfo 1.2.x 和 2.x 中已更改的函数。
编辑
临时修复以使系统正常运行：
修复 TZInfo 2.x 导致时区导入失败
注意：我不确定这是否是所有情况下的最佳修复方法，但对于我数据库中具有格式正确的纪元时间戳的日期，这似乎效果很好。
第 990 行
已更改
Time.zone.at(@tz.utc_to_local(timestamp))
为
Time.zone.at(timestamp)
脚本因最后访问时间为 nil 值而崩溃
最后访问时间实际上是从数据库导入的。因此，我们将其添加到正在获取的内容中。
第 131 行
已更改
SELECT userid
, username
, homepage
, usertitle
, usergroupid
, joindate
, email
, password
, salt
FROM #{TABLE_PREFIX}user
WHERE userid > #{last_user_id}
ORDER BY userid

SELECT userid

, joindate
, lastvisit
, email

FROM #{TABLE_PREFIX}user
WHERE userid > #{last_user_id}

我遇到了同样的问题，不确定 Haddoq 在说修改第 990 行时指的是哪个文件。
对其他人来说，它是 vbulletin5.rb

在导入帖子时，通过向 vbulletin5.rb 添加一些错误处理，解决了“UTF-8 中无效的字节序列”问题。
这是我用第 450 行替换的代码。我不会 Ruby，所以这有点像个 hack。
begin
raw = raw.gsub(/(\\\\r)?\\\\n/, "\\n")
.gsub("\\t", "\\t")
rescue => error
p error.message
p raw
end
当我重新运行脚本时，它将有问题的帖子打印到了控制台。
然后我搜索了控制台中的一些唯一文本，并在 MySQL 中运行了以下命令：
select * from vb_text where rawtext LIKE '%and then my fish ate my car keys%' limit 10;
这给了有问题的行的 nodeid，所以我用它来更新该行，我可以将其输入到修复了错误文本的查询中。
update vb_text set rawtext='POST FAILED TO MIGRATE (or a corrected version of the post)' where nodeid IN (159079);

你好！你能分享一下你是如何检查 sha1 属性是否为 nil 的代码吗？
我遇到了同样的问题：
/discourse/app/models/upload.rb:246:in `base62_sha1': undefined method `hex' for nil:NilClass (NoMethodError)
谢谢！
附言//
对于可能遇到相同问题的人。
在文件 discourse\app\models\upload.rb 中找到：
“#{Upload.base62_sha1(sha1)}#{extension.present? ? \”.#{extension}\” : \"\"}”
替换为：
除非 sha1.nil?
“#{Upload.base62_sha1(sha1)}#{extension.present? ? \”.#{extension}\” : \"\"}”
结束
另外，我还遇到了：
discourse/vendor/bundle/ruby/2.7.0/gems/activesupport-6.1.6.1/lib/active_support/core_ext/time/calculations.rb:56:in `at': can't convert nil into an exact number (TypeError)
错误。
要修复此问题：
在 discourse\script\import_scripts\vbulletin.rb 中找到：
user.suspended_at = parse_timestamp(user["bandate"])
user.suspended_till = 200.years.from_now
并替换为：
user.suspended_at = parse_timestamp(user["bandate"].to_i)
user.suspended_till = 200.years.from_now.to_i

您好，
我正在使用 Ubuntu 22.04 LTS，并希望将 vBulletin 转换为 Discourse。
DB_HOST = "172.17.0.5"
DB_USER = "root"
DB_PASSWORD = "*******"
当我输入 RAILS_ENV=production bundle exec ruby script/import_scripts/vbulletin.rb 时，
会出现此错误：
1: from /var/www/discourse/vendor/bundle/ruby/2.7.0/gems/rack-mini-profiler-3.0.0/lib/mini_profiler/profiling_methods.rb:83:in `profile_method'
/var/www/discourse/vendor/bundle/ruby/2.7.0/gems/rack-mini-profiler-3.0.0/lib/mini_profiler/profiling_methods.rb:83:in `alias_method': undefined method `call' for class `Redis::Client' (NameError)
Did you mean? caller
我该如何解决？
您使用的是开发安装还是标准安装？我认为您不需要添加 RAILS_ENV=production，因为您没有生产数据库。
我使用的是标准安装。
参考了 https://www.vultr.com/docs/how-to-install-discourse-on-ubuntu-20-04/。
我无法在 docker 安装中使用 Mysql。我在 discourse docker 镜像中安装了 MariaDB。
root@localhost-app:/var/www/discourse# service mysql start
mysql: unrecognized service
root@localhost-app:/var/www/discourse#
所以我创建了一个 mysql docker 镜像并将我的 vBulletine 数据库上传到那里。mysql docker 镜像的 IP 地址是 172.17.0.5。
谢谢。
我按照以下步骤操作：
遵循了使用 Docker 容器
- 标准安装 discourse。(discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub)。
- 下载 mysql docker 并将我的 vBulletin 数据库上传到那里。
我使用root@localhost:/opt/discourse# mysql -h 172.17.0.5 -P 3306 --protocol=tcp -u root -p命令进行了检查。 root@localhost:/opt/discourse#./launcer enter appapt-get update && apt-get install libmysqlclient-dev mysql-server-5.7失败。
因此，我安装了apt-get update && apt-get install libmariadb-dev mariadb-server- 我无法在 docker 中运行 mysql。
root@localhost-app:/var/www/discourse# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)
在整个 docker 目录中都没有 mysqld.sock。无法通过 `find` 命令找到。
root@localhost-app:/var/www/discourse# sudo service mysql start
mysql: unrecognized service
- 我参考了 https://www.baeldung.com/docker-cant-connect-local-mysql 并在“172.17.0.5”上使用了 mysql docker 镜像。
gem install mysql2
gem install php_serialize
在安装 libmariadb-dev 之前，`gem install mysql2` 不起作用。
- 运行
su discourse -c 'bundle install --no-deployment --without test --without development --path vendor/bundle'
出现错误，所以我删除了 gemfile.lock 和 .bundle 文件并重试。
- 之后我尝试了。
export DB_NAME="vb3" # Change this to the name of VB3 database.
export DB_USER="root"
export DB_PASSWORD="mypassword"
export DB_HOST="172.17.0.5"
cd /var/www/discourse
su discourse -c 'bundle exec ruby script/import_scripts/vbulletin.rb'
但是脚本生成了错误。

我该如何解决？
谢谢。
我遇到了同样的问题，你已经解决了吗？谢谢！
我也遇到了这个，你成功绕过它了吗？
