我找到了几个关于这个问题的网页,但没有一个解决了我的问题。
即使我做了:
pip show
我明白了:

这是因为操作系统安装了不同的请求模块以及本地安装的python依赖项。
可以通过升级请求来解决:
pip install requests
或
pip3 install requests
答案 1 :(得分:5)
您确实有混合设置(apt
和pip
都用于安装系统范围,这很常见),它确实与所需的模块支持版本不匹配请求(和pip v1.5.6也很旧)。
requests
(哪个版本?可能来自pip install
)可能需要:
urllib3:1.21.1 - 1.22
chardet:3.0.2 - 3.1.0
你有:
来自python-urllib3的urllib3(1.9.1)1.9.1-3 debian包
chardet(2.3.0)来自python-chardet 2.3.0-1 debian package
两个选项:
要么将requests
降级到您的操作系统发行版中的版本(请参阅apt show python-requests
提供的内容),要么将旧版本降级到pypi.org,或
或安装更新的urllib3和chardet(您可以从用户级别(pip install
pip手动从pipy.org手动下载轮文件并对其进行--user
,包括任何依赖项)安装选项)或在virtualenv。
您可以在virtualenv(apt show python-virtualenv
)中测试所有内容。它甚至应该在其虚拟环境中为你部署一个更新的点。同样possible在用户级别(--user
)旁边安装一个较新的pip 10.0.1以及你的OS销售点,但你需要careful。祝你好运!

我通过使用 pip 手动更新请求包解决了这个问题:

答案 6 :(得分:1)
只需要sudo pip install --upgrade requests
。
没有sudo,您将得到Permission denied
,
并且如果您添加--user
,它将不会安装到系统python中。
此后,pip list
没有收到RequestsDependencyWarning。
我系统上的输出:
$ sudo pip install --upgrade requests

在任何时候,都要检查源代码,特别是在开发人员在注释中留下清晰说明的情况下,例如在这种情况下。 (也许作者应该更具体一些,并把它放在错误消息中,是的)
打开const Header = () => {
const firstName = "Ashraf";
const lastName = "Fathi";
const date = new Date();
const hours = date.getHours();
let timeOfDay;
const styles = {
color: ""
}
if (hours < 12) {
timeOfDay = "Good morning"
styles.color = "#ff474d"
}
else if (hours >= 12 && hours < 17) {
timeOfDay = "Good afternoon"
styles.color = "#7b5dff"
}
else {
timeOfDay = "Good night"
styles.color = "#01ff41"
}
return(
<div>
<h1 className="navbar" style={styles}>{timeOfDay} {`${firstName} ${lastName}`} It is currently {hours} clock</h1>
</div>
)
}
并搜索vi /usr/lib/python2.7/site-packages/requests/__init__.py
。
check_compatibility(
然后,您知道兼容def check_compatibility(urllib3_version, chardet_version):
urllib3_version = urllib3_version.split('.')
assert urllib3_version != ['dev'] # Verify urllib3 isn't installed from git.
# Sometimes, urllib3 only reports its version as 16.1.
if len(urllib3_version) == 2:
urllib3_version.append('0')
# Check urllib3 for compatibility.
major, minor, patch = urllib3_version # noqa: F811
major, minor, patch = int(major), int(minor), int(patch)
# urllib3 >= 1.21.1, <= 1.24 <------------------ here
