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

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()
