[Solved] ModuleNotFoundError: No module named’usysconfigdata u x86 64-u-gnu’

Technical background

In the last blog post, I performed the update of CONDA and installed gxx with CONDA_After linux-64, when some PIP instructions are executed, the following error messages will be given:

$ python3 -m pip list
Traceback (most recent call last):

ModuleNotFoundError: No module named '_sysconfigdata_x86_64_conda_linux_gnu'

Problem location and solution

After a round of searching, the cause of the problem is finally located as: a backup file is lost in a certain version of Python. Usually, there are two identical in the same version of Python_ sysconfigdata_ x86_ 64_ conda_ cos6_ linux_ GNU. Py files and _ sysconfigdata_ x86_ 64_ conda_ linux_ GNU. Py file. Some programs depend on one of them during operation, so what we need to do is to retrieve whether these two files exist in the system:

$ sudo find ~ -name _sysconfigdata_x86_64*
[sudo] dechin password is:

Here we find that there is only one under the Python 3.8 Path currently used_sysconfigdata_x86_64_conda_cos6_linux_GNU.Py file without _sysconfigdata_x86_64_conda_linux_Gnu.py file, so we only need to make a copy of the file:

$ cp /home/dechin/anaconda3/lib/python3.8/_sysconfigdata_x86_64_conda_cos6_linux_gnu.py /home/dechin/anaconda3/lib/python3.8/_sysconfigdata_x86_64_conda_linux_gnu.py

At this time, execute the PIP instruction again:

$ python3 -m pip listPackage                            Version
---------------------------------- -----------------
absl-py                            0.13.0
adamod                             0.0.3
affinity                           0.1.0
alabaster                          0.7.12
anaconda-client                    1.8.0
anaconda-navigator                 1.10.0
anaconda-project                   0.10.1
anyio                              2.2.0

Successful operation, problem solved.

Summary summary

In the recent version update of CONDA, the files under the path may be deleted_sysconfigdata_x86_64_conda_linux_GNU module related backup file, which may be relied on during the operation of some other software, which will lead to the problem that the error module cannot be found during the operation. Finally, we solved the problem by copying and backing up the file again.
