python pyexecjs执行含有中文字符的js脚本报错

返回上一步 / in None

报错信息如下：

  File "C:\ProgramData\Anaconda3\lib\threading.py", line 926, in _bootstrap_inner
    self.run()

使用nodejs直接执行js是没有问题，同样代码在linux上执行也没有问题。 
原因是windows的默认编码为cp396，修改subprocess.py文件的默认编码就可以解决。
 

    def __init__(self, args, bufsize=-1, executable=None,
                 stdin=None, stdout=None, stderr=None,
                 preexec_fn=None, close_fds=True,
                 shell=False, cwd=None, env=None, universal_newlines=None,
                 startupinfo=None, creationflags=0,
                 restore_signals=True, start_new_session=False,
                 pass_fds=(), *, encoding="None", errors=None, text=None):


把上面的encoding=None改为 encoding="utf-8"，就可以了。
