没有名为“gunicorn”的模块

Question

我正试着用古尼康和nginx来供应烧瓶 这是我的systemd单元配置文件

[Unit]
Description=Gunicorn instance to serve odooErp
After=network.target

[Service]
User=tito
Group=www-data
WorkingDirectory=/home/tito/peg/odoo_api/peg_api
Environment="PATH=/home/tito/peg/odoo_api/peg_api/env/bin"
ExecStart=/home/tito/peg/odoo_api/peg_api/env/bin/gunicorn --workers 3 --bind unix:odooErp.sock -m 007 wsgi:app

[Install]
WantedBy=multi-user.target

当我启动服务时，尽管使用pip安装了gunicorn，我还是遇到了以下错误

[0;1;31m●[0m odooErp.service - Gunicorn instance to serve productionOdoo

Answer 1

如果运行多个版本的Python，有时可能会出现一些混乱；简单地运行pip将为一个版本而不是另一个版本安装模块。我通常更喜欢运行'-m pip install gunicorn'

Answer 2

这可能是因为模块的路径不正确

如果您在windows上，则可以在您的环境中按如下方式设置路径： 搜索此电脑>；房地产>；左角的高级系统设置>；右下角的环境变量>；在用户变量中，单击路径，然后单击新建并设置路径
