在Windows上安装pymysql时出现ImportError：无法导入名称FIELD_TYPE

Question

我正在尝试在windows 64位上为python 3.3设置pymysql。

我通过这个链接成功安装了easy_install。然后我运行了python distribute_setup.py，之后easy_install就可以用了。

现在每次我尝试运行easy_install pymysql时，都会出现

Downloading/unpacking pymysql
  Downloading PyMySQL-0.5.tar.gz
  Running setup.py egg_info for package pymysql
    Traceback (most recent call last):
      File "<string>", line 16, in <module>
      File "c:\users\cc\appdata\local\temp\pip-build-Cc\pymysql\setup.py", line 7, in <module>
        version_tuple = __import__('pymysql').VERSION
      File ".\pymysql\__init__.py", line 28, in <module>
        from constants import FIELD_TYPE
    ImportError: cannot import name FIELD_TYPE
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

  File "<string>", line 16, in <module>

  File "c:\users\cc\appdata\local\temp\pip-build-Cc\pymysql\setup.py", line 7, in <module>

    version_tuple = __import__('pymysql').VERSION

  File ".\pymysql\__init__.py", line 28, in <module>

    from constants import FIELD_TYPE

ImportError: cannot import name FIELD_TYPE

----------------------------------------
Command python setup.py egg_info failed with error code 1 in c:\users\cc\appdata\local\temp\pip-build-Cc\pymysql
Storing complete log in C:\Users\Cc\pip\pip.log

最开始的错误是“无法导入名称'constants'”，然后我运行了easy_install constants，现在错误变成了上面的那个。

编辑

仔细看了一下，他们说对于python 3.3，应该执行

echo "Building Python 3.0 version in ./py3k..."
rm -fr ./py3k
mkdir py3k
cp -rf pymysql py3k/
cp setup.py py3k/
cp setup.py.py3k.patch py3k/
cp CHANGELOG py3k/
cp README.rst py3k/
cp LICENSE py3k/
cd py3k
2to3 .|patch -p0
patch setup.py setup.py.py3k.patch
cd ..

有没有人知道我怎么在Windows上执行这个命令2to3 .|patch -p0？

我觉得你安装的是python2的版本。

试试这个：

easy_install pymysql3
