python 运行 execjs 出现错误 UnicodeEncodeError: ‘gbk‘ codec can‘t encode character ‘\ufffd‘

Python javascript sequence execjs


异常解读

该异常的格式一般为:

UnicodeEncodeError: ‘gbk’ codec can’t encode character ‘\ufffd’ in position 160: illegal multibyte sequence

该异常出现的场景为在 Windows 电脑下使用 Python execjs 运行指定的 JS 文件,但 JS 文件中包含中文

异常解决方案

该问题解决需要 修改 你电脑 Python 安装目录下 lib 文件夹里面的一个文件,名字叫做 subprocess.py

例如在我本地为 :
python 运行 execjs 出现错误 UnicodeEncodeError: ‘gbk‘ codec can‘t encode character ‘\ufffd‘
通过任意文本编辑器打开该文件,在文件中检索 encoding,找到如下位置:
python 运行 execjs 出现错误 UnicodeEncodeError: ‘gbk‘ codec can‘t encode character ‘\ufffd‘
修改 encoding=Noneencoding = "utf-8"



代码位置:

 def __init__(self, args, bufsize=-1, executable=None,
stdin=None, stdout=None, stderr=None,
preexec_fn=None, close_fds=_PLATFORM_DEFAULT_CLOSE_FDS,
shell=False, cwd=None, env=None, universal_newlines=False,
startupinfo=None, creationflags=0,
restore_signals=True, start_new_session=False,
pass_fds=(), *, encoding="utf-8", errors=None):
"""Create new Popen instance."""

保存文件,解决问题。
