Question

如果这是一个简单的解决方案，请提前道歉，我已经找到了一个没有运气的答案。

我试图在亚马逊的Linux AMI上安装mysql-connector [-python]软件包。出于我的目的，我想使用Python 3.4。我已经用yum安装了Python 3.4和pip-3.4，并且已经成功安装了几个软件包：

    pip-3.4 list

给出

    numpy (1.11.1)
    pip (6.1.1)
    setuptools (25.1.4)
    virtualenv (15.0.2)

然而，当我尝试：

    sudo pip-3.4 install mysql-connector-python

我得到了

    Collecting mysql-connector-python
  Could not find a version that satisfies the requirement mysql-connector-python (from versions: )
  No matching distribution found for mysql-connector-python

sudo pip-3.4 install mysql-connector-python --allow-external mysql-connector-python给出了同样的错误。谷歌搜索建议我使用sudo pip-3.4 install mysql-connector-python-rf --allow-external mysql-connector-python-rf，但这会产生错误：

    Collecting mysql-connector-python-rf
    Using cached mysql-connector-python-rf-2.1.3.tar.gz
    Installing collected packages: mysql-connector-python-rf
    Running setup.py install for mysql-connector-python-rf
    Complete output from command /usr/bin/python3.4 -c "import setuptools, tokenize;__file__='/tmp/pip-build-hotls6f7/mysql-connector-python-rf/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-wzpbgx5g-record/install-record.txt --single-version-externally-managed --compile:

   or: -c --help [cmd1 cmd2 ...]
   or: -c --help-commands
   or: -c cmd --help

error: option --single-version-externally-managed not recognized

----------------------------------------
Command "/usr/bin/python3.4 -c "import setuptools, tokenize;__file__='/tmp/pip-build-hotls6f7/mysql-connector-python-rf/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-wzpbgx5g-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-hotls6f7/mysql-connector-python-rf

我尝试了很多东西，例如

    echo https://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.1.3.tar.gz >> requirements.txt
    sudo -H pip-3.4 install -r ./requirements.txt

给出了类似的错误，

    sudo pip-3.4 install https://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.1.3.tar.gz

会产生相同的error: option --single-version-externally-managed not recognized错误。我还应该注意，pip建议我使用sudo pip-3.4 install --upgrade pip进行升级，但是当我这样做时，pip会完全中断，即使pip-3.4 list或pip-3.4 --version也会给我pkg_resources.VersionConflict: (pip 8.1.2 (/usr/local/lib/python3.4/site-packages), Requirement.parse('pip==6.1.1'))。

我对于该怎么做有点失落，我们将非常感谢任何帮助。

在这里回答我自己的问题，我知道它并没有解决我直接遇到的问题，但我设法安装了mysql-connector，以便在Python3（.4）中，import mysql.connector不会给出任何错误。这是我做的：

    wget http://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.0.4.zip#md5=3df394d89300db95163f17c843ef49df
    unzip mysql-connector-python-2.0.4.zip
    cd mysql-connector-python-2.0.4
    sudo python3 setup.py install

现在，在Python3中：

    >>>import mysql.connector
    >>>

我仍然很好奇为什么我之前收到错误error: option --single-version-externally-managed not recognized。我猜这是setuptools的问题，但我已将其升级到最新版本（以及virtualenv）。

通过pip-3.4
