python - 如何使用 pip 1.5(在 Python 上)安装和升级外部托管的包存储库？

Question

让我们以 https://pypi.python.org/pypi/py-dom-xpath 为例.在这种情况下，包存储库托管在 http://code.google.com/p/py-dom-xpath/ 中。 .

我在 Windows 7 上使用 Python 2.7。

pip install py-dom-xpath

Downloading/unpacking py-dom-xpath
  Could not find any downloads that satisfy the requirement py-dom-xpath
  Some externally hosted files were ignored (use --allow-external py-dom-xpath to allow).
Cleaning up...
No distributions at all found for py-dom-xpath
Storing debug log for failure in C:\Users\insrkum\pip\pip.log

pip install --allow-external py-dom-xpath

You must give at least one requirement to install (see "pip help install")

pip install --allow-all-external py-dom-xpath

Downloading/unpacking py-dom-xpath
  Could not find any downloads that satisfy the requirement py-dom-xpath
  Some insecure and unverifiable files were ignored (use --allow-unverified py-dom-xpath to allow).
Cleaning up...
No distributions at all found for py-dom-xpath
Storing debug log for failure in C:\Users\insrkum\pip\pip.log

我尝试使用 --index-url 选项但没有成功。有效的是以下命令

pip install http://py-dom-xpath.googlecode.com/files/py-dom-xpath-0.1.tar.gz

这不是安装外部托管包存储库的最佳方式。我有兴趣使用 --allow-external 或 --allow-all-external。 我还想了解如何将 --upgrade 选项用于外部托管的包存储库。

Answer 1

Pip 1.5 是安全的:你需要 --allow-external 来下载外部托管的包 和 --allow-unverified 从“http”站 pip 下载。

你可以用

pip install --allow-all-external --allow-unverified py-dom-xpath py-dom-xpath

和

pip install --allow-all-external --allow-unverified py-dom-xpath py-dom-xpath --upgrade
