pip install -r requirements.txt [Errno 2] No such file or directory: 'requirements.txt'
提问by siama
I am setting up the base for a django project, I have cloned a repo and I have just created a virtual environment for the project in the same directory. But when I try to run the command 'pip install -r requirements.txt' in the project directory I get this error:
我正在为 django 项目设置基础，我已经克隆了一个 repo，我刚刚在同一目录中为该项目创建了一个虚拟环境。但是当我尝试在项目目录中运行命令“pip install -r requirements.txt”时，我收到此错误：
[Errno 2] No such file or directory: 'requirements.txt'
[Errno 2] 没有这样的文件或目录：'requirements.txt'
I believe I'm just running it in the wrong directory, but I don't really know where I should run it. Do you have any idea where the file could be located?
我相信我只是在错误的目录中运行它，但我真的不知道应该在哪里运行它。您知道该文件的位置吗？

I know it's kind of late, but if you are using virtual environment just use pip freeze > requirements.txtcommand to create the requirements file first.
我知道这有点晚了，但是如果您使用的是虚拟环境，请先使用pip freeze > requirements.txt命令创建需求文件。

A better way of doing this is write this on the root directory of your terminal:
更好的方法是在终端的根目录中写入：
find . -regex '.*requirements.txt$'
It will search in your root directory and all subfolders for a file called requirements.txt. After the command response, you can get the directory and run the pip install -r requirements.txton it.
它将在您的根目录和所有子文件夹中搜索名为requirements.txt. 命令响应后，您可以获取目录并在其pip install -r requirements.txt上运行。

If you are facing this issue while using a docker or flowing getting started guide from docker site then you need to update your Docker file.
如果您在使用 docker 或从 docker 站点获取入门指南时遇到此问题，那么您需要更新 Docker 文件。
just add following line to create the requirements.txt file before the line "RUN pip install --no-cache-dir -r requirements.txt" in your Dockerfile
只需添加以下行以在 Dockerfile 中的“RUN pip install --no-cache-dir -r requirements.txt”行之前创建 requirements.txt 文件
RUN pip freeze > requirements.txt

Try using this in your terminal then go to the directory and use the pip install command.
尝试在终端中使用它，然后转到目录并使用 pip install 命令。
find -name "requirements.txt"
