uwsgi: error while loading shared libraries: libicui18n.so.58: cannot open shared object file: No...

注：本文中运行的uwsgi是使用miniconda管理的虚拟环境中安装运行的，但是问题的原理是通用的，读者可根据自己的情况自行解决。

出现这个问题的原因：缺失pyicu模块导致，pyicu模块是python国际化模块，所以出现上述问题后需要安装pyicu，然后将对应的库链接到lib64文件夹下

#使用conda安装在虚拟环境下
$ conda install pyicu

安装完毕后，进入自己虚拟环境的lib文件夹下，比如我新建的conda虚拟环境名称叫djangotest，先进入miniconda安装目录，进入envs文件夹下，就能看到自己的虚拟环境文件夹，进入文件夹下的lib文件夹：

$ cd /miniconda3/envs/djangotest/lib
$ ls

可以看到libicui18n.so.64，libicudata.so.64， libicuuc.so.64三个文件，将这三个文件软连接到/lib64文件夹下（我的是64位机）：

$ ln -s /miniconda3/envs/djangotest/lib/libicui18n.so.64 /lib64/libicui18n.so.58
$ ln -s /miniconda3/envs/djangotest/lib/libicuuc.so.64 /lib64/libicuuc.so.58
$ ln -s /miniconda3/envs/djangotest/lib/libicudata.so.64 /lib64/libicudata.so.58
