常用命令
更新pip版本:python -m pip install --upgrade pip
同时安装多个包:pip install TensorFlow pygame ipython
列出过期的包:pip list --outdated
更新:pip install --upgrade 包名
pip-review

is a convenience wrapper around pip
. It can list available updates by deferring to pip list --outdated
. It can also automatically or interactively install available updates for you by deferring to pip install
.

马大哈aip
pip install aip 报错【Windows,python3.6】
ERROR: Could not find a version that satisfies the requirement aip (from versions: none)
ERROR: No matching distribution found for aip
【解决】【pip install baidu-aip】
老大难aubio
pip intall aubio 报错 【Windows 10,python3.7.6】
Installing collected packages: numpy, aubio Running setup.py install for aubio ... error
加上清华镜像,下载安装numpy无误,下载aubio无误,安装aubio继续报错
Installing collected packages: aubio Running setup.py install for aubio ... error
出现ERROR具体处有:
ERROR: Command errored out with exit status 1:
…一串之后…
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd3 in position 0: invalid continuation byte
查看过期包,发现setuptools过期,用pip install --upgrade setuptools更新完,重新安装aubio,报错依旧。
参考CSDN博客,在https://pypi.org/project/aubio/0.4.3a2/#files下载aubio-0.4.3a2-cp35-cp35m-win_amd64.whl,然后进入对应文件夹,用pip install aubio-0.4.3a2-cp35-cp35m-win_amd64.whl,报错:
ERROR: aubio-0.4.3a2-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
参考CSDN博客,直接将whl名称改为aubio-0.4.3a2-cp35-none-win_amd64.whl,仍然报错:
ERROR: aubio-0.4.3a2-cp35-none-win_amd64.whl is not a supported wheel on this platform.
安装wheel模块后,参考cnblogs博客,查询当前pip支持的文件版本号如下:
sys.version_info < (3, 8))) [('cp37', 'cp37m', 'win_amd64'), ('cp37', 'none', 'win_amd64'), ('cp37', 'none', 'any'), ('cp3', 'none', 'any'), ('cp36', 'none', 'any'), ('cp35', 'none', 'any'), ('cp34', 'none', 'any'), ('cp33', 'none', 'any'), ('cp32', 'none', 'any'), ('cp31', 'none', 'any'), ('cp30', 'none', 'any'), ('py3', 'none', 'win_amd64'), ('py37', 'none', 'any'), ('py3', 'none', 'any'), ('py36', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]
重新pip安装,报错依旧。突发奇想,将上述whl名称改为aubio-0.4.3a2-cp37-cp37m-win_amd64.whl,然后pip安装,成功!但是import失败,说明版本不匹配还是不行??
但是因为下载的实际为cp35版本的,不知道会不会有隐患。所以有unsintall了上述whl,又下载了最新版的aubio-0.4.9源码,python setup.py install 安装,然后报错:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd3 in position 0: invalid continuation byte
以为是编码的问题,修改HPCP,重复上述安装,报错:
...pythonpython37scriptsaubio-0.4.9pythonextaubio-types.h(5): fatal error C1083: 无法打开包括文件: “aubio-generated.h”: No such file or directory error: command 'F:\zhaoqin\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.13.26128\bin\HostX86\x64\cl.exe' failed with exit status 2
崩溃之后,找到两个貌似有用的链接https://blog.csdn.net/lying_byr/article/details/92802719 和 https://stackoverflow.com/questions/40018405/cannot-open-include-file-io-h-no-such-file-or-directory/50210015#50210015
在VS2017上重新下载了相关组件。添加了两个环境变量:……2017CommunityVCToolsMSVC14.16.27023inHostx86x64 和 ……2017CommunityCommon7IDE ,报错信息不变。
【目前,删除了VS2017,暂不安装aubio】
