MySQL连接器Python PIP安装离线安装
我正在尝试在没有Internet连接的服务器上安装MySQL-Connector-Python模块。我可以在8.0.19之后安装任何版本。我尝试了很多，但失败了。我尝试了两种方法。
OS信息： Windows Server 2019-64位
Python信息： Python 3.8.0-64位
第一种方法：
我从下面的URL下载并安装了MSI，它已成功安装，但是当我在命令行上键入“ PIP列表”时，我会看到该软件包未安装。
下载URL： href =“ https://dev.mysql.com/downloads/connector/python/”
< a 强>第二种方法：
我从下面的URL下载了WHL文件，并尝试使用“ PIP安装”安装。但是在安装过程中，我会收到下面分享的错误。我一直在处理这个问题约2-3个小时。你能帮助我吗？什么原因是什么？
下载URL： https://pypi.org/project/project/project/mysql-connector-python/#files < /a>
软件包： mysql_connector_python-8.0.0.29-py2.py3-none-any.whl（342.0 kb视图哈希斯）
错误： 警告：重试（重试（总计= 0，连接= none，read = none，redirect = none，status = none））在连接通过'protocoleRror破裂（'Connection duded''。 ）由远程主机'，none，10054，none））'：/simple/protobuf/

I'm trying to install the mysql-connector-python module on a server with no internet connection. I can install any version after 8.0.19. I tried many but failed. I tried two ways for this.
OS Info:
Windows Server 2019 - 64 Bit
Python Info:
Python 3.8.0 - 64 Bit
First way:
I downloaded and installed MSI from the url below, it was installed successfully, but when I type "pip list" on the command line, I see that the package is not installed.
Download URL:
https://dev.mysql.com/downloads/connector/python/
Second way:
I downloaded whl file from below url and tried to install with "pip install". But during installation I am getting the error I shared below. I've been dealing with this issue for about 2-3 hours. Can you help me? What would be the reason?
Download URL:
https://pypi.org/project/mysql-connector-python/#files
Package:
mysql_connector_python-8.0.29-py2.py3-none-any.whl (342.0 kB view hashes)

您必须为连接器版本安装正确的依赖项（Protobuf）版本。
就我而言，我正在安装mysql_connector_python-8.1.0-cp38-cp38-win_amd64，并且需要Protobuf版本＆gt; = 4.21.1，＆＆＆＆＆lt; = 4.21.12。 （ https://dev.mysql.com/doc/relnotes/connector-python/en/news-8-1-0.html ）
以确定正确的ProtoBuf版本在Internet连接的机器上进行Python并安装PIP安装连接器。它将自动下载并安装正确的依赖项版本。然后，您可以搜索该版本的车轮，下载其轮子并在离线机上安装。
You must install the correct dependency (protobuf) version for your connector version.
In my case, I was installing mysql_connector_python-8.1.0-cp38-cp38-win_amd64 and it requires protobuf version >= 4.21.1, <=4.21.12. (https://dev.mysql.com/doc/relnotes/connector-python/en/news-8-1-0.html)
To figure the correct protobuf version for which case, you can install python on a internet connected machine and pip install the connector. It will automatically download and install the correct dependency version. Then you can search for that version wheel, download its wheel and install on the offline machine.
