Can not get mysql-connector-python to install in virtualenv
提问by slim
I'm using Amazon Linux AMI release 2013.09. I've install virtualenv and after activation then I run pip install mysql-connector-python, but when I run my app I get an error: ImportError: No module named mysql.connector. Has anyone else had trouble doing this? I can install it outside of virtualenv and my script runs without issues. Thanks in advance for any help!
我正在使用 Amazon Linux AMI 版本 2013.09。我已经安装了 virtualenv 并在激活后运行 pip install mysql-connector-python，但是当我运行我的应用程序时出现错误：ImportError: No module named mysql.connector. 有没有其他人在这样做时遇到问题？我可以在 virtualenv 之外安装它，我的脚本运行没有问题。在此先感谢您的帮助！

Several things. There is an inconsistency in package naming so you may want to do:
几件事。包命名不一致，因此您可能需要执行以下操作：
pip search mysql-connector
to find out what it is called on your platform. I got two results mysql-connector-pythonand mysql-connector-repackaged.
找出它在您的平台上的名称。我得到了两个结果mysql-connector-python和mysql-connector-repackaged。
so try this first:
所以先试试这个：
pip install mysql-connector-python
this may additionally give an error like this:
这可能还会出现这样的错误：
Some externally hosted files were ignored (use
--allow-external mysql-connector-python to allow).
so finally this should do the job:
所以最后这应该可以完成工作：
pip install mysql-connector-python --allow-external mysql-connector-python

I've battled with this and tried upgrading pip and setuptools but actually it seems all you need to do is:
我已经与此作斗争并尝试升级 pip 和 setuptools 但实际上似乎您需要做的就是：
sudo pip install virtualenv --upgrade
Once you've upgraded virtualenv, create a new virtual environment, activate it and try installing with:
升级 virtualenv 后，创建一个新的虚拟环境，激活它并尝试安装：
pip install https://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.1.3.tar.gz
(you might need to update the url, but that's the current one)
（您可能需要更新网址，但这是当前网址）

I have managed to overcome this problem by entering mysql-connector-pythonpackage URL, taken from MySQL page, directly to the requirements file, instead of dependency name.
我设法通过输入mysql-connector-python从 MySQL 页面获取的包 URL 直接到需求文件而不是依赖项名称来克服这个问题。
My requirements file looks like this:
我的需求文件如下所示：
bson==0.4.2
https://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.0.4.tar.gz
pymongo==3.2.1
After creating virtualenv and switching into it I am executing
在创建 virtualenv 并切换到它之后，我正在执行
$ pip install -r ./requirements
And pip is doing the rest of the work, i.e., downloading, extracting and installing.
而 pip 正在做剩下的工作，即下载、解压和安装。

Also something that can go wrong: Don't name your own module mysql
还有一些可能出错的地方：不要命名你自己的模块 mysql
import mysql.connectorwill fail because the import gives the module in the project precedence over site packages and yours likely doesnt have a connector.pyfile.
import mysql.connector将失败，因为导入使项目中的模块优先于站点包，而您的可能没有connector.py文件。
