pip install 报错问题解决
有时在用pip install命令安装python库时出现红字报错
1.报错:ReadTimeoutError: HTTPSConnectionPool(host=’pypi.python.org’, port=443): Read timed out.

ReadTimeoutError: HTTPSConnectionPool(host='pypi.python.org', port=443): Read timed out.
错误原因:连不上pip的源,下载依赖包失败
解决(推荐):在pip安装所在文件夹路径下,创造python文件(.py)
import os ini="""[global] index-url = https://pypi.doubanio.com/simple/ [install] trusted-host=pypi.doubanio.com """ pippath=os.environ["USERPROFILE"]+"\\pip\\" if not os.path.exists(pippath): os.mkdir(pippath) with open(pippath+"pip.ini","w+") as f: f.write(ini)
在cmd上运行这个.py文件即可
之后再用pip install安装指令下载速度会非常快
2.报错:UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xd3 in position 7: ordinal not in range(128)
Exception: Traceback (most recent call last): File “c:\python27\lib\site-packages\pip\basecommand.py”, line 215, in main status = self.run(options, args) File “c:\python27\lib\site-packages\pip\commands\install.py”, line 324, in run requirement_set.prepare_files(finder) File “c:\python27\lib\site-packages\pip\req\req_set.py”, line 380, in prepare_files ignore_dependencies=self.ignore_dependencies)) File “c:\python27\lib\site-packages\pip\req\req_set.py”, line 620, in _prepare_file session=self.session, hashes=hashes) File “c:\python27\lib\site-packages\pip\download.py”, line 821, in unpack_url hashes=hashes File “c:\python27\lib\site-packages\pip\download.py”, line 659, in unpack_http_url hashes) File “c:\python27\lib\site-packages\pip\download.py”, line 880, in _download_http_url file_path = os.path.join(temp_dir, filename) File “c:\python27\lib\ntpath.py”, line 85, in join result_path = result_path + p_path UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xd3 in position 7: ordinal not in range(128)
报错原因:pip安装Python包会加载目录包含中文字符,ascii不能编码
解决:python目录 Python27\Lib\site-packages 建一个文件sitecustomize.py
import sys sys.setdefaultencoding('gbk')
python会自动运行这个文件
