根因分析
请求的包版本在配置的索引上不存在，或包名拼写错误，或索引不可达。
English
The requested package version does not exist on the configured index, or the package name is misspelled, or the index is unreachable.
解决方案
-
90% 成功率
Run `pip index versions foo` to list available versions, then install an existing one.
-
85% 成功率
Check spelling and use `pip install foo` without pinning, or specify `--extra-index-url https://pypi.org/simple`.
无效尝试
常见但无效的做法:
-
95% 失败
The version genuinely does not exist; retrying does not change index contents.
-
85% 失败
pip version is unrelated to index availability.
