UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 281: illegal multibyte sequence
An error occured.
IndexError: list index out of range

主要是这句话：UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 281: illegal multibyte sequence
解决办法
找到python安装目录的lib\site-packages\jupyterlab\commands.py文件，
第83行：
self.proc = self._create_process(
cwd=cwd,
env=env,
stderr=subprocess.STDOUT,
stdout=subprocess.PIPE,
universal_newlines=True
)
修改为：
self.proc = self._create_process(
cwd=cwd,
env=env,
stderr=subprocess.STDOUT,
stdout=subprocess.PIPE,
universal_newlines=True,
encoding="UTF-8"
)
也就是增加一个参数encoding=“UTF-8”，就可以了。
