  • window7下安装第三方包报错及解决 凯

    window7 64位下安装第三方包,,比如安装yaml的exe执行文件,会

     报错及解决:python version 2.7(3.4) required,which was not found in the registry

    方法:新建一个register.py 文件,把一下代码贴进去,保存

    #
    # script to register Python 2.0 or later for use with win32all
    # and other extensions that require Python registry settings

    import sys
     
    from _winreg import *
     
    # tweak as necessary
    version = sys.version[:3]
    installpath = sys.prefix
     
    regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
    installkey = "InstallPath"
    pythonkey = "PythonPath"
    pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
        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()

    用python2.7的idle执行一下即可,会提示“python 2.7 is already registered”

    window7 下安装的是python3.4的32位,没有_winreg模块导致无法按脚本,可直接在注册表中直接添加

    LOCAL_CURRENT_USER\software\python\PyhtonCore下创建3.4目录,添加InstallPath和PythonPath项,具体如下图:

             InstallPath:   D:\python\Python34

             PythonPath:  D:\python\Python34;D:\python\Python34\Lib\;D:\python\Python34\DLLs\
