Does anyone know what's wrong? Didn't have this issue a month ago. Please help! Just in case: the error above popped up when i wrote pip install gender-guesser.

I met the same problem and this might work for you cd into the location where metadata.json exists and type this command cp metadata.json METADATA then you could do sudo pip install
我遇到了同样的问题，这可能对你有用 cd 到 metadata.json 存在的位置并输入这个命令 cp metadata.json METADATA 然后你可以做 sudo pip install

我遇到了同样的问题。
Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: '/home/myusr/.local/lib/python3.6/site-packages/pip-19.0.1.dist-info/METADATA'
由于环境错误，无法安装软件包：[Errno 2] 没有这样的文件或目录：'/home/myusr/.local/lib/python3.6/site-packages/pip-19.0.1.dist-info/METADATA'
I followed the angrypig298 solution but it didn't work for me. The first part was ok.
我遵循了angeredpig298 解决方案，但它对我不起作用。第一部分没问题。
conda install tqdm
But the second part got the same error of pip cannot find the METADATA file.
但是第二部分出现了同样的错误 pip 找不到 METADATA 文件。
pip install gender-guesser
Based on other answers, I used the find command to find the METADATA in my machine and I found it in a subdirectory.
根据其他答案，我使用 find 命令在我的机器中查找 METADATA 并在子目录中找到它。
find ~/.local/ -name "*METADATA*" | grep pip
The METADATA was in
元数据在
/home/myuser/.local/lib/python3.6/site-packages/pip-19.0.1.dist-info/pip-19.0.1.dist-info/METADATA
I copy it to the path where the pip command is looking for it, which is one directory above it.
我将它复制到 pip 命令正在查找它的路径，这是它上面的一个目录。
/home/myuser/.local/lib/python3.4/site-packages/pip-9.0.1.dist-info/METADATA
Then the pip worked normally.
然后点子正常工作。
