目标WSGI脚本无法加载为Python模块+ ImportError：没有模块命名

Question

使用mod_wsgi部署我的烧瓶应用程序时出错。这是错误日志：

df <- gather(df2, key = "key", value = "value", A, B, C)
df <- unite(df, "key", key, kind, type, sep = "")
df <- spread(df, key, value)
df
##   id A1U_sweet A2F_dip A3U_bbq B1U_sweet B2F_dip B3U_bbq C1U_sweet C2F_dip
## 1  1         1       2       1         1       2       1        NA      NA
## 2  2        NA      NA      NA         4       1       2         4       1
## 3  3         2       4       7         2       4       7        NA      NA
##   C3U_bbq
## 1      NA
## 2       2
## 3      NA

我在itemcatalog目录中有一个 init .py文件，我做了一些搜索，发现也许python没有将我的itemcatalog识别为包，这是什么原因？

Python全局安装但后来我也尝试在虚拟环境中安装它。

这是虚拟主机的代码：

这是<VirtualHost *:80> ServerName 18.194.244.229 ServerAdmin admin@18.194.244.229 WSGIDaemonProcess itemcatalog python-path=/var/www/itemcatalog:/var/www/itemcatalog/venv/lib/python2.7/site-packages WSGIProcessGroup itemcatalog WSGIScriptAlias / /var/www/itemcatalog/itemcatalog.wsgi <Directory /var/www/itemcatalog/> WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>

中的文件结构

Answer 1

而不是：

WSGIDaemonProcess itemcatalog python-path=/var/www/itemcatalog:/var/www/itemcatalog/venv/lib/python2.7/site-packages

使用：

WSGIDaemonProcess itemcatalog python-path=/var/www \
  python-home=/var/www/itemcatalog/venv

Python路径必须是包的父目录，而不是包目录本身。

不使用python-path设置虚拟环境，而是使用官方文档中所述的python-home：
