技术背景

在上一篇博客中执行过conda的更新以及用conda安装了gxx_linux-64之后，再执行pip的一些指令时，就会给出如下所示的报错：

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

问题定位与解决

经过一圈的检索，最后对问题的出现原因定位为：在某一个版本的python中丢失了一个备份文件，通常在同一个版本的python下会有两个相同的_sysconfigdata_x86_64_conda_cos6_linux_gnu.py文件和_sysconfigdata_x86_64_conda_linux_gnu.py文件。而在某些程序的运行过程中会依赖于其中的一个，因此我们需要做的就是检索系统中是否存在有这两个文件：

$ sudo find ~ -name _sysconfigdata_x86_64*
[sudo] dechin 的密码： 
/home/dechin/anaconda3/lib/python3.8/_sysconfigdata_x86_64_apple_darwin13_4_0.py
/home/dechin/anaconda3/lib/python3.8/__pycache__/_sysconfigdata_x86_64_apple_darwin13_4_0.cpython-38.pyc
/home/dechin/anaconda3/lib/python3.8/_sysconfigdata_x86_64_conda_cos6_linux_gnu.py

这里我们发现当前使用的python3.8路径下只有一个_sysconfigdata_x86_64_conda_cos6_linux_gnu.py文件而没有_sysconfigdata_x86_64_conda_linux_gnu.py文件，因此我们只需要讲该文件拷贝一份即可：

$ 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

此时再重新执行pip的指令：

$ 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
...

成功运行，问题解决。
