Error content: importerror: C extension: DLL load failed: access denied. not built. If you want to import pandas from the source directory, you may need to run ‘python setup.py build_ ext –inplace –force’ to build the C extensions first.

Reason for error reporting: it may be caused by deleting the installation dependency package of pandas in the environment by mistake, or by deleting the anti-virus software. Generally, the latter does it.

Solution 1: uninstall pandas: PIP uninstall pandas , reinstall: PIP install pandas

if you use the above method, you may make mistakes

Error content: error: could not install packages due to an oserror: [errno 13] permission denied: ‘your project path \ venv \ lib \ site packages \ pandas\_ libs\
tslibs\period.cp36-win_ amd64.pyd’
Check the permissions.

Error reason: it means that there are missing files in the folder reported above and cannot be downloaded.

Solution 2: delete the folder and reinstall pandas. For example, in this example, delete pandas under site packages. Remember to delete pandas under site packages instead of site packages. Don’t make a mistake. Delete all the environment and you’ll be finished.
