Members fellow, is not in use pip command to install third-party libraries encountered the following problem?
This situation can be really a headache ah. . After several twists and turns, finally found that the most effective solution
First download the package to be installed first down, no matter what way
Here I use the Thunder, the link would not have said it, after pip command displays the download links to third party libraries, as shown in Figure
Here I use the Thunder, of course, what methods can be downloaded
As shown, download a good file. In the documents in a comfortable position, I'm on the D drive, you know, comfortable position
The next thing on the simple direct input cmd in
pip install D:/lxml-4.4.1-cp37-cp37m-win32.whl
This is equivalent to a locally installed it, pay attention, after install the downloaded package is the path, file name, but also bring.
In this way so the installation was successful! ! ! ! !
What questions can leave a message oh.
