安装时报错信息

Building jupyterlab assets (build:prod:minimize)

An error occured.
IndexError: list index out of range
See the log file for details:  C:Users*****AppDataLocalTempjupyterlab-debug-kx1tois9.log

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libsite-packagesjupyterlabcommands.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。
