Question

我有一个Django项目，我想在端口80运行manage.py runserver。在我的项目中，我使用Wand库，并使用自制软件安装了freetype和imagemagick：

brew install freetype imagemagick

要在端口80 runserver运行Django，需要使用sudo运行，但是当我使用sudo运行runserver时，它似乎找不到imagemagick：

$ sudo ~/.pyenv/versions/myproject/bin/python manage.py runserver 0.0.0.0:80

在另一个端口上没有sudo的情况下运行此工作正常，我怎样才能使它在端口80上工作？

清理不同的`imagemagick`次安装

首先，last version of imagemagick is currently not supported by wand，因此如果您不使用它，可以安全地将其卸载，以避免干扰启动imagemagick@6 wand $ brew uninstall imagemagick }}：
```
imagemagick
```
这是可选的。

如果您要保留两个版本的安装，我仍然会取消wand取消旧版dylib的链接，MAGICK_PATH可以在我的计算机上运行而不设置$ brew unlink imagemagick Unlinking /usr/local/Cellar/imagemagick/7.0.7-11... 72 symlinks removed：
```
imagemagick@6
```
关联$ brew link imagemagick@6 Linking /usr/local/Cellar/imagemagick@6/6.9.9-23... 76 symlinks created：
```
$ sudo python3.6 -c "from wand.image import Image"
```
检查这是否足够（正如我所说，此设置已在我的机器上运行）：
```
MAGICK_PATH
```
如果没有出现错误，您就完成了！您也可以清除MAGICK_PATH变量，因为它现在已经过时了。

如果以上几点没有帮助

您应该保留wand，因为它是sudo查找库的关键。要将var传播到sudo会话，请修改$ sudo visudo设置：

Defaults env_keep += "MAGICK_PATH"

添加行MAGICK_PATH，保存并退出。您可能需要启动新的终端会话才能使更改生效。这将确保将sudo变量传递给body {margin: 0} html, body {height: 100vh} .container { display: flex; height: 100vh; /* mandatory (100% of the viewport height) */ background: #ddd; opacity: 0.6; } .container > div { flex: 1; text-align: center; transition: .3s; max-width: 20%; padding: 8em 0; background: #000; opacity: 0.9; } .container > div:hover { transition: .5s; max-width: 40%; background: #333; flex-grow: 2; cursor: pointer; color: #fff; }会话。

Answer 2

将您环境的相关部分传播到root环境中：

crossjoin_df <- function(df1, df2, temp_col = ".k") {
  # `$`(df1, temp_col) <- 1
  df1 <- df1 %>% 
    mutate(!!temp_col :=  1)

  # `$`(df2, temp_col) <- 1
  df2 <- df2 %>% 
    mutate(!!temp_col :=  1)

  left_join(df1, df2, by = temp_col) %>% select(-one_of(temp_col))

} 

params <- data.frame(k = c(11,10),
                 n = c(27,26))

data <- data.frame(a = 1:3,
               b = 4:6)

crossjoin_df(params, data)

#   k  n a b
#1 11 27 1 4
#2 11 27 2 5
#3 11 27 3 6
#4 10 26 1 4
#5 10 26 2 5
#6 10 26 3 6
