pip install时遇到ReadTimeoutError详解编程语言

在pip install时遇到ReadTimeoutError，详细报错为

File “d:/python37/lib/contextlib.py”, line 130, in __exit__
self.gen.throw(type, value, traceback)
File “d:/python37/lib/site-packages/pip/_vendor/urllib3/response.py”, line 443, in _error_catcher
raise ReadTimeoutError(self._pool, None, “Read timed out.”)
pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host=’pypi.tuna.tsinghua.edu.cn
‘, port=443): Read timed out.

 解决的方法：

　　install后面加上 –default-timeout=100

eg：

pip install --default-timeout=100 jupyter
