环境错误2

Python version 3.3 required, which was not found in the registry

python registry函数语法

在windows下安装numpy的时候, 出现了"Python version 3.3 required, which was not found in the registry"的错误.

类似的有:Python version 2.7 required, which was not found in the registry

大致意思是说:注册表没有对应的信息. 只要执行一个python脚本,将HKEY_CURRENT_USER (HKCU)注册就好.

2.7版本的可以参照: http://blog.csdn.net/zklth/article/details/8117207

3.3版本的可以参照: https://gist.github.com/embray/6042780#file-win_register_python-py

相关的说明:

其中python3版本的可以执行以下脚本:

from __future__ import print_function

import sys

try:
    from winreg import *
except ImportError:
    from _winreg import *

# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix

regpath = "SOFTWARE\\Python\\Pythoncore\\{0}\\".format(version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "{0};{1}\\Lib\\;{2}\\DLLs\\".format(
    installpath, installpath, installpath)

def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print("*** Unable to register!")
            return
        print("--- Python", version, "is now registered!")
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print("=== Python", version, "is already registered!")
        return
    CloseKey(reg)
    print("*** Unable to register!")
    print("*** You probably have another Python installation!")

if __name__ == "__main__":
    RegisterPy()
