我在 oracle Linux EL7 上有 python 3.6.8 我使用安装了 pip3
yum install python36-pip
但是，当我调用 pip3 时，它会出现库错误
pip3
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

我试图看看是否有任何替代 pyexpat.*.so 但似乎没有 ldd 在下面的最后一行是输出
[root@whf00jkd python3.6]# ldd /usr/lib64/python3.6/lib-dynload/pyexpat.cpython-36m-x86_64-linux-gnu.so

我搜索了 libexpat.so.1
[root@whf00jkd python3.6]# whereis libexpat.so.1
libexpat.so: /usr/lib/libexpat.so.1 /usr/lib/libexpat.so /usr/lib64/libexpat.so.1 /usr/lib64/libexpat.so
[root@whf00jkd python3.6]# ls -ltr /usr/lib/libexpat.so.1
lrwxrwxrwx. 1 root root 17 Apr 1 2019 /usr/lib/libexpat.so.1 -> libexpat.so.1.6.0
[root@whf00jkd python3.6]# ls -ltr /usr/lib64/libexpat.so.1
lrwxrwxrwx. 1 root root 17 Apr 1 2019 /usr/lib64/libexpat.so.1 -> libexpat.so.1.6.0
并在 /usr/lib64/python3.6/lib-dynload/ 中添加了一个链接 libexpat.so.1 -> /usr/lib/libexpat.so.1 但这并没有消除错误
请帮忙
