Description of your issue, suggested solution and other information

It appears that (recently?) Fox.com has started throwing this error for me (ERROR: pycrypto not found. Please install it.) I've made sure that pycrypto is installed (I used both pip and pip3 install pycrypt).

Any ideas on how to make sure youtube-dl knows that it's installed?

[dstftw]

Most likely you have several instances of python installed.

[jschwalbe]

@dstftw Glad you're confident this is the problem, but can you be of any help in solving my problem?

[jschwalbe]

For others (and perhaps my future self -- hello there, self!): I ended up having to run pip2.7 install pycrypto (pip2.7 rather than just pip) because indeed it was installing to the wrong instance. Frustrating.

pip2.7 install pycrypto worked for me to fix ERROR: pycrypto not found. Please install it.
