在这篇文章【[Python模块]Windows环境安装PyV8并执行js语句:https://blog.csdn.net/sc_lilei/article/details/79946029】的基础上填坑补充:
在window下安装那个【python2的pyv8:https://pan.baidu.com/s/1rKPqPVidhHzwLT9eYiqFOw】时出现【 Python version 2.7 required, which was not found in the registry】,参考【https://blog.csdn.net/zklth/article/details/8117207】,就是用你的python2执行以下脚本,然后再去点击安装那个pyv8的exe文件。
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()
但运行测试的python脚本又发现一个问题【ImportError: DLL load failed: 找不到指定的模块。】,参考【win10环境下python3如何使用PyV8:https://www.pythonheidong.com/blog/article/324801/】&【https://github.com/emmetio/pyv8-binaries】这篇文章中提到的python2中只有python2.6才适用,果断切换到python2.6,不过还是失败了,算了,暂时搁置了。
