感谢@simbabque，我找到了解决方案。 我的问题是我正在使用系统native uwsgi_psgi，该系统是通过系统Perl安装进行编译的，并且与本地Perlbrew安装不兼容。 该邮件列表线程建议uwsgi在Perlbrew范围内重新编译，以便能够（仅）与本地Perlbrew安装一起使用。 因此，通过执行以下编译，我可以启动Perl应用程序： ``` curl http://uwsgi.it/install | bash -s psgi /home/soeren/perl5/perlbrew/bin/uwsgi ``` 但是，上面显示的命令不是最好的方法，因为它缺少所有其他重要的编译开关（例如pcre，jit）。 随着时间的推移，我将通过进一步的编译开关来改善此答案。
