我正在尝试将一个 zip 文件上传到 AWS Lambda，该文件主要包含 python 包，大小为 300MB。我清楚地了解，如果我们直接使用 AWS SDK 上传，这超出了可以上传到 Lambda 的 zip 的限制。因此，这是行不通的。

为了克服这个问题，我决定下载/tmp目录中的包并将它们导入到主文件中（参考此处）。我将所需的包压缩为pkgs.zip并将其上传到AWS S3。然后我使用requests将它们解压到 来下载它们/tmp/。

def get_pkgs(url):
    import requests
    import io
    import zipfile
    print("Getting Packages...")
    re = requests.get(url)
    z = zipfile.ZipFile(io.BytesIO(re.content))
    print("Extracting Packages...")
    z.extractall("/tmp/")
    print("Packages are downloaded and extracted.")

def attempt_import():
    print("="*50)
    print("ATTEMPT TO IMPORT DEPENDENCIES...")
    print("="*50)
    import numpy
    import scipy
    import six
    print("IMPORTING DONE.")

def main():
    URL = "https://s3-ap-southeast-1.amazonaws.com/BUCKET_NAME/pkgs.zip"
    get_pkgs(URL)
    attempt_import()

def lambda_handler(event, context):
    main()
    return …

我已升级到新版本的Pycharm。在终端中，它说的bash-3.2$不是我的用户名。当我尝试安装库时，它说找不到pip命令：

bash: pip: command not found

所以我安装了pip：

bash-3.2$ sudo easy_install pip
Searching for pip
Best match: pip 8.1.2
pip 8.1.2 is already the active version in easy-install.pth
Installing pip script to /usr/local/bin
Installing pip3.5 script to /usr/local/bin
Installing pip3 script to /usr/local/bin

Using /Library/Python/2.7/site-packages
Processing dependencies for pip
Finished processing dependencies for pip</i>

好吧，现在我所要做的就是使用pip安装库，对吗？

但是，这发生了：

bash-3.2$ pip install pandas
bash: pip: command not found

我不明白我该怎么做才能真正安装pip。还是我应该使用sudo easy_install [library]？

我想安装一些库来学习机器学习。我说我需要升级 pip，但是当我尝试安装它时

$ pip install --upgrade pip

我使用 Django Rest Framework 制作了一个简单的 API，列出了学生们所尊敬的大学。列出数据的 url 是http://127.0.0.1:8000/api/v1/students/。尝试API后，我收到以下错误
