该脚本安装在非 PATH 目录中

在使用 pip 安装 Jupiter Notebook 的过程中，系统提示脚本安装在 PATH 之外的文件夹中。这会引起任何问题吗？我该如何解决？

答案1

关于如何修复该问题的答案就在您发布的日志中。

添加位置

c:\users\рубена\appdata\local\programs\python\python37\Scripts

到 Python 路径目录。

你可以按照以下答案来回答，而不必重复说明：将目录添加到 Python 路径

这会引起什么问题吗？

如果您尝试访问该脚本而不指定确切位置，Python 将无法找到它。只有您知道这是否真的会给您带来问题。

答案2

对于 Windows，请执行以下步骤：

  1. 转到文件资源管理器。导航至 C: → 用户 →（您的用户名）→ AppData → 本地 → 程序 → Python → Python38-32（您的 Python 版本）→ 脚本

  2. 复制此路径，例如
       C:\Users\(your username)\AppData\Local\Programs\Python\Python38-32\Scripts

  3. 右键单击“计算机”、“我的电脑”或“此电脑”图标 → 选择“属性”。单击“高级系统设置”（在左侧）。（要求时输入管理员密码。）在“系统属性”窗口中，单击“环境变量”（靠近底部）。在“环境变量”窗口中，在PATH“系统变量”下搜索。选择它并单击“编辑…”。在变量值中添加分号（“;”）并粘贴您在步骤 1 中复制的路径。

  4. 关闭命令提示符窗口。打开一个新的命令提示符窗口。

您现在可以运行您想要运行的命令。

答案3

对我来说，Stese 发布的解决方案不起作用并且根本没有帮助，因此我发布它来更新帖子并帮助社区。

对于使用MAC-OS的用户

解决方案 1：

尽管我已经正确配置了$PYTHONPATH，但终端仍然无法找到安装的包。

因此，我打开了~/.bashrc（或者~/.zshrc如果您使用的是新的zsh，适用于 mac-os Catalina 10.15.x 或更新版本）并粘贴以下内容：

export PATH="${PATH}:/Users/caio.hc.oliveira/Library/Python/3.7/bin"
export PYTHONPATH="${PYTHONPATH}:/Users/caio.hc.oliveira/Library/Python/3.7/bin"

保存文件并重新启动终端。

重要的：这是配置为我的 Python 路径的示例。找到你的并替换。

解决方案 2：

如果仍然找不到该包，还有另一种可能性，即发布alias指向可执行文件的指向。

因此，在同一个文件中~/.bashrc（或者如果您使用zsh它~/.zshrc），您只需在末尾附加：

alias jupyter='/Users/caio.hc.oliveira/Library/Python/3.7/bin/jupyter'

保存并重新启动终端。

重要的：这是配置为我的 Python 路径的示例。找到你的并替换。

您可以使用它来指向任何可执行文件；）
