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

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

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()
