python - 我试图使用带有代码“pipenv install python”的pipenv安装numpy，但它不断出现错误

Question

我试图使用带有代码“pipenv install python”的 pipenv 安装 numpy，但它不断出现错误。下面是我在尝试安装时在终端中得到的最后一个输出。有人可以帮我调试一下吗。

当我尝试安装 numpy 时，出现以下错误：锁定失败！回溯（最后一次调用）：文件“c:\users\calibest\appdata\local\programs\python\python38-32\lib\site-packages\pipenv\patched\notpip_vendor\urllib3\response.py”，第 425 行，在 _error_catcher 产生文件“c:\users\calibest\appdata\local\programs\python\python38-32\lib\site-packages\pipenv\patched\notpip_vendor\urllib3\response.py”，第 507 行，在读取数据中= self._fp.read(amt) if not fp_closed else b"" File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\site-packages\pipenv\patched\notpip_vendor\cachecontrol \filewrapper.py”，第 62 行，读取数据 = self.__fp.read(amt) 文件“c:\users\calibest\appdata\local\programs\python\python38-32\lib\http\client.py” ，第 454 行，读取 n = self.

During handling of the above exception, another exception occurred:

默认情况下应安装 Python。尝试使用pipenv --py查看安装 python 解释器的详细信息。
