在 Python 中下载 (pytube) 库时出现问题

Question

我想从 Python 个名为 (pytube) 的库下载一个库当我在命令面板中放置下载命令[pip install git + https://github.com/pytube/pytube]时，会出现以下输出：

Collecting git+https://github.com/pytube/pytube
  Cloning https://github.com/pytube/pytube to c:\users\jit\appdata\local\temp\pip-req-build-w3q3fwqn

Requirement already satisfied (use --upgrade to upgrade): pytube==10.6.1 from git+https://github.com/pytube/pytube in c:\users\jit\appdata\local\programs\python\python39\lib\site-packages
Using legacy 'setup.py install' for pytube, since package 'wheel' is not installed.

WARNING: You are using pip version 20.2.3; however, version 21.0.1 is available.
You should consider upgrading via the 'c:\users\jit\appdata\local\programs\python\python39\python.exe -m pip install --upgrade pip' command.

于是我在cmd面板中写入提示[pip install --upgrade pip]的内容，得到如下输出：

Installing collected packages: pip
  Attempting uninstall: pip
    Found existing installation: pip 20.2.3
    Uninstalling pip-20.2.3:
      Successfully uninstalled pip-20.2.3
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'C:\Users\jit\AppData\Local\Temp\pip-uninstall-pnqylmmj\pip.exe'
Consider using the `--user` option or check the permissions.

在另一次安装尝试中，我在 (PyCharm) 程序中的（终端）中键入了命令：

Collecting git+https://github.com/pytube/pytube
  Cloning https://github.com/pytube/pytube to c:\users\jit\appdata\local\temp\pip-req-build-o5uke_cl
  Running command git clone -q https://github.com/pytube/pytube 'C:\Users\jit\AppData\Local\Temp\pip-req-build-o5uke_cl'

而且我没有安装库成功！这是为什么？我如何找到解决方案？

Answer 1

尝试安装 pytube3。 pip install pytube3

对于pip的警告只是一个警告，因为你没有使用最新版本，使用这个命令升级它：python -m pip install --upgrade pip

Answer 2

欢迎使用 Whosebug!!!

对于已安装的 pytube，请尝试升级到最新版本 pytube-10.6.1:

python -m pip install --upgrade pytube

对于 pip install --upgrade pip 错误，这是由于访问不足造成的：

ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'C:\Users\jit\AppData\Local\Temp\pip-uninstall-pnqylmmj\pip.exe'

解决方案：

Consider using the `--user` option or check the permissions.

尝试：

python -m pip install --upgrade pip --user

或者以管理员身份打开命令提示符并执行相同的命令。
