Error reason

Reason for error :

Some dependent modules are missing, so the installation reports an error.Friends who report errors after installing other third-party modules can also use the following solutions to choose one of them! ! !

Solution 1

• distutils : distutils is the installer responsible for building third-party Python libraries in the standard library. It can be used to install and publish Python modules. distutils is useful for simple distributions, but lacks functionality.
• setuptools : setuptools is an enhanced version of distutils that is not included in the standard library. It extends many functions and can help developers better create and distribute Python packages. Most Python users will use the more advanced setuptools module.

(1) Install setuptools:

pip install --upgrade setuptools

(2) Install Microsoft's VS Install, and install your operating system package and modified library:

pip install nes-py --no-cache-dir
pip install --upgrade pip setuptools wheel

(3) Then try to install the lxml module again:

pip install lxml

Workaround 2 (for all mod installations)

Note: This method is applicable to the installation of all third-party modules, friends can modify the package name! ! !

Error "ERROR: Failed building wheel for xxx (a certain library), this error message indicates that the corresponding .whl file is missing:

(1) The python version corresponds to the .whl file, download address : https://pypi.org/

(2) Search for the package name (search for what you need if you want to install any module):

(3) Find the corresponding version and click:

(4) Click to download :

(5) Download the corresponding whl file (cp38: python version is 3.8, amd64: computer window 64 bits, note: be sure to download the corresponding version of your computer and Python!）

(6) Find the path under the file and execute the installation command (my whl file is placed under the E disk, followed by the path and package name of the package):

pip install E:\lxml-4.9.2-cp38-cp38-win_amd64.whl  

(7) The installation is successful:
