Answer 1

這是因為 PyPI 禁用了對 API 的非 HTTPS 訪問

https://mail.python.org/pipermail/distutils-sig/2017-October/031712.html

作為您可以使用的解決方法

$ pip install xxxx -i https://pypi.python.org/simple/

Answer 2

不幸的是，以前的答案都不適合我。

恕我直言，pip / distutils 選擇破壞 http 存儲庫上的軟件包是非常愚蠢的。

我認為更好的選擇是：

• pip/distutils 默認使用 https

• 如果出現錯誤，例如 403，pip 必須建議您“包 repo 在 http 上，您要下載嗎？”

仍然在 2020 年，許多 Python 2 包都在 http 存儲庫上； 根據他們的決定，這些軟件包的安裝被破壞了。

我的工作解決方案是一個非常簡單的python核心模塊補丁：

--- /usr/local/lib/python2.7/urllib2.py.original
+++ /usr/local/lib/python2.7/urllib2.py
@@ -427,6 +427,9 @@
             req = meth(req)

         response = self._open(req, data)
+        if protocol == "http" and response.code == 403 :
+            if isinstance(fullurl, basestring) and fullurl.startswith("http://pypi.python.org/packages/source/d/distribute/") :
+                return    self.open(fullurl.replace("http://", "https://"), data = data, timeout = timeout)

         # post-process response
         meth_name = protocol+"_response"

工作：如果失敗的 url 在 http 上，請在 https 上重試。

我知道它有點難看，但它非常清楚，您也可以快速恢復到原始模塊（在應用此補丁之前制作/usr/local/lib/python2.7/urllib2.py的副本） .

Answer 3

唯一對我有用的解決方案是使用 easy_install 而不是 pip

Answer 4

得到錯誤。 問題出在 pip 試圖安裝軟件包的倉庫中。
