jupyter labextension install @jupyterlab/github
jupyter labextension install @jupyterlab/debugger
jupyter labextension install @krassowski/jupyterlab-lsp

UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 281: illegal multibyte sequence

An error occured.
IndexError: list index out of range
See the log file for details:  C:\Users\*****\AppData\Local\Temp\jupyterlab-debug-kx1tois9.log
 

主要是這句話：UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 281: illegal multibyte sequence

解決辦法

找到python安裝目錄的lib\site-packages\jupyterlab\commands.py檔案，
第83行：

   self.proc = self._create_process(
        cwd=cwd,
        env=env,
        stderr=subprocess.STDOUT,
        stdout=subprocess.PIPE,
        universal_newlines=True
    )
 

修改為：

    self.proc = self._create_process(
        cwd=cwd,
        env=env,
        stderr=subprocess.STDOUT,
        stdout=subprocess.PIPE,
        universal_newlines=True,
        encoding="UTF-8"
    )

也就是增加一個引數encoding=“UTF-8”，就可以了。
