英文:
Requirement.txt file for Render while using conda environment
问题
我是新手，但我正在尝试使用Render的Web服务设置Flask应用程序，我在requirements.txt文件上遇到问题，部署一直失败。
我已经使用conda创建了虚拟环境，并使用"conda list -e > requirements.txt"命令创建了要求文件，但似乎无法使其工作。在服务器端的构建命令中，我尝试了默认选项：$ pip install -r requirements.txt，但没有起作用，以及$ conda install --file requirements.txt，但它没有识别conda命令。我应该怎么做？
英文:
I am new with this stuff but I am trying to set up flask app using Render's web service and I have problem with requirements.txt file and deploying keeps failing.
I have created virtual environment with conda and made requirement file using "conda list -e > requirements.txt" command but can't seem to make it work. As build command in server side I tried default option: $ pip install -r requirements.txt which didnt work and $ conda install --file requirements.txt but it didn't recognize conda command. What should I do?

conda export 和 pip export 的格式不同。如果你想要以 pip 格式导出依赖项，请使用：
pip freeze > requirements.txt
然后只需使用 pip install -r requirements.txt
如果你想要创建一个新的环境，并使用由 conda 导出的 requirements.txt 文件，请使用：
conda list -e > requirements.txt
然后：
conda create --name <your-new-env> --file <requirements file>
但如果你需要在现有环境中安装依赖项，请使用：
conda install --file <requirements file>
关于为什么无法识别 conda 命令，请提供更多信息更新你的问题，我会相应编辑我的回答。
英文:
conda export and pip export don't have the same format. If you want to export dependencies in pip format use:
pip freeze > requirements.txt
And then just use pip install -r requirements.txt
If you want to make a new env that will use requirements.txt file exported by conda, use:
conda list -e > requirements.txt
and then:
conda create --name <your-new-env> --file <requirements file>
But if you need to install dependencies in an existing env, use the:
conda install --file <requirements file>
As to why it didn't recognize conda command, please update your question with more info, and I will edit my answer accordingly.
