Question

嗨，我正在使用spyder，我想升级点子（我的实际点子版本是9.0.3）。

我尝试通过cmd键入以下内容来实现此目的：

python -m pip install --upgrade pip

但是我收到一条错误消息：

Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(10054, "Connessione in corso interrotta forzatamente dall'host remoto", None, 10054, None))': /simple/pip/
Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(10054, "Connessione in corso interrotta forzatamente dall'host remoto", None, 10054, None))': /simple/pip/

Requirement already up-to-date: pip in c:\program files\python36\lib\site-packages
You are using pip version 9.0.3, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我还尝试使用此代码（设置其他代理-因为我的公司的笔记本电脑有防火墙）来升级pip：

python -m pip install --upgrade pip --proxy="http://user:password@proxyname.com:portnumber"

但我再次遇到错误：

Exception:
Traceback (most recent call last):
  File "C:\Program Files\Python36\lib\shutil.py", line 544, in move
    os.rename(src, real_dst)
PermissionError: [WinError 5] Accesso negato: 'c:\\program files\\python36\\lib\\site-packages\\pip-9.0.3.dist-info\\description.rst' -> 'C:\\Users\\indelicl\\AppData\\Local\\Temp\\pip-7kqirkkb-uninstall\\program files\\python36\\lib\\site-packages\\pip-9.0.3.dist-info\\description.rst'

在处理上述异常期间，发生了另一个异常：

    status = self.run(options, args)

我该怎么做？

Answer 1

异常消息包含您要查找的信息。

PermissionError: [WinError 5] Accesso negato: 'c:\\program files\\python36\\lib\\site-packages\\pip-9.0.3.dist-info\\description.rst' -> 'C:\\Users\\indelicl\\AppData\\Local\\Temp\\pip-7kqirkkb-uninstall\\program files\\python36\\lib\\site-packages\\pip-9.0.3.dist-info\\description.rst'

这表明您没有足够的权限来编辑pip文件。特别是PermissionError异常类型和Accesso negato（Permission denied）错误消息。

为解决此问题，您需要使用sudo运行命令（在Linux系统上）或以管理员身份运行命令（在Windows上）。

您似乎在Windows上，因此应该能够右键单击“命令提示符”图标，然后单击“以管理员身份运行”，然后从提升的外壳中运行命令。值得一提的是，默认情况下您不应该这样做，只有在知道有必要的情况下才应使用提升的权限运行（在这种情况下就是如此）。

尝试通过cmd升级点，没有结果
