pip3抛出未定义的符号: XML_SetHashSalt
我在oracle EL7上安装了python3.6.8，我使用
yum install python36-pip然而，当我调用pip3时，它出现了库错误。
pip3

请帮帮忙

libexpat.so.1指向错误的位置。用
export LD_LIBRARY_PATH=/lib64/:${LD_LIBRARY_PATH}ldd /usr/lib64/python3.6/lib-dynload/pyexpat.cpython-36m-x86_64-linux-gnu.so
linux-vdso.so.1 => (0x00007fff073f1000)

我也犯了同样的错误。
系统信息
- VM与CentOS 7.9
- 3.6
溶液
我们安装了另一个软件，它带来了自己版本的libexpat。我们还修改了env变量LD_LIBRARY_PATH以包含该软件的lib目录。这导致pip加载错误的库。
在取消LD_LIBRARY_PATH /从LD_LIBRARY_PATH中删除该软件后，一切都很好。

这就是为我解决问题的原因。我使用Python3.6并尝试使用PIP安装一个模块。我得到了下面的错误。
/opt/rh/rh-python36/root/usr/lib64/python3.6/lib-dynload/pyexpat.cpython-36m-x86_64-linux-gnu.so:未定义符号：ImportError：XML_SetHashSalt
给出ldd之后的路径，以找到映射。
ldd /opt/rh/rh-python36/root/usr/lib64/python3.6/lib-dynload/pyexpat.cpython-36m-x86_64-linux-gnu.so
检查- libexpat.so.1的映射。在我的例子中，它指的是不正确的甲骨文路径-- /u01/oracle/product/12.1.0.2/lib/libexpat.so.1
因此，我在上面的目录中重命名了libexpat.so.1。
重命名后，再次给ldd，它应该指向/lib64 64/libexpat.so.1。
一旦映射被纠正，我就能够完成pip安装。
谢谢大家的帮助。
