I was trying to install numpy using pipenv with the code "pipenv install python" but it kept on coming up with errors. Below is the last output I got in my terminal while trying to install. Could someone please help me debug this.

When I was attempting to install numpy I got the following error: Locking Failed! Traceback (most recent call last): File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\site-packages\pipenv\patched\notpip_vendor\urllib3\response.py", line 425, in _error_catcher yield File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\site-packages\pipenv\patched\notpip_vendor\urllib3\response.py", line 507, in read data = 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", line 62, in read data = self.__fp.read(amt) File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\http\client.py", line 454, in read n = self.readinto(b) File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\http\client.py", line 498, in readinto n = self.fp.readinto(b) File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\socket.py", line 669, in readinto return self._sock.recv_into(b) File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\ssl.py", line 1241, in recv_into return self.read(nbytes, buffer) File "c:\users\calibest\appdata\local\programs\python\python38-32\lib\ssl.py", line 1099, in read return self._sslobj.read(len, buffer) socket.timeout: The read operation timed out

During handling of the above exception, another exception occurred:

  • You might want to use a more specific title that would help draw the attention from someone who ran into this problem, e.g., "Why do I get timeout errors trying to install Numpy". In addition, if you are trying to install Numpy, you should just use that in your command `pipenv install numpy` – HanSooloo Jun 27 '20 at 18:23

Python should be installed by default. Try using pipenv --py to see the details of where the python interpreter is installed.
