I hope that this article "the method of installing the third-party library in Pycharm" can help you solve your doubts.

When installing libraries, be sure to pay special attention to the dependencies between packages

First, install third-party libraries directly in Pycharm

1. Open Pycharm, click File in the upper left corner, and click Settings. , as shown in the following figure

2. Enter the interface shown below and click the + sign in the upper right corner.

3. To search for the libraries you want to install, click install, as shown in the following figure

Install the library through cmd

1. First download the .whl file corresponding to the computer python version on the website https://www.lfd.uci.edu/~gohlke/pythonlibs/.

2. Then go to the venv- > > Scripts folder in the corresponding Pycharm environment and put the downloaded .whl file into it (note that in which environment you want to install the library and enter the corresponding folder), enter this folder in cmd, and use the pip command to install the appropriate library, as shown in the following figure

3. After the installation is successful, use import to test.

III. Other

When we use pip to install third-party libraries, we are sometimes reminded that the pip version is too low to install, and we need to upgrade pip.

1. Upgrade pip directly in Pycharm

2. Upgrade pip on the command line, as shown in the following figure. Note here that my administrator's name is wwww, so when upgrading pip, it must be under this folder, that is, I must upgrade as an administrator. Just enter the command for pip update.

Add: pycharm failed to install third-party libraries solution

Sometimes the update of the third-party database has been failed, guess is the source of the problem, replaced by the source of Douban still can not be updated, with reference to online search to finally solve the problem, here is a solution.

Method 1: change the source in pycharm.

Built-in is a foreign source, replaced by domestic access is faster and more stable, providing several available sources:

Tsinghua: https://pypi.tuna.tsinghua.edu.cn/simple

Douban: https://pypi.douban.com/simple/

Ali: https://mirrors.aliyun.com/pypi/simple/

I used Ali. Step: File > Setting > + > Manage Repositories > + add a new URL (such as https://mirrors.aliyun.com/pypi/simple/ above) to solve the problem.

Method 2: update the target library directly from the command line

Cmd command: python-m pip install requests-- trusted-host=pypi.py

Thon.org-trusted-host=pypi.org-trusted-host=files.pythonhosted.org

This is more straightforward, you need to know the name of the library you need, of course, the operation is not as good as the first one.

There is also an episode, the low version of pip may also lead to installation failure, first update pip to v20.1 with the command line, and then inexplicably OK when installing other libraries
