Hi pycisTopic team,

Thanks for developing this package. I'm trying to install it following the installation guide as follows:

git clone https://github.com/aertslab/pycisTopic.git
cd pycisTopic
pip install -e .

However I get the following error

Could you please help me out with this?

Thanks!

Do you have a recent version of pip (as that one should install binary versions of packages by default)?

Upgrade pip with:

pip install -U pip

Which version of python and which OS are you using?

As described in the error message, if you follow the instructions to install rust via rustup here and then rerun pip install -e . you should be able to avoid this error.

i m too having the same problem , how did you solve

[ghuls]

@sherlockmoriarity Which version of python, pip do you have and on which OS are you running it?

Here are the ways you can fix it.

• First make sure your python is 64 bits and not 32 bits. If you have a 32 bits python change it to 64 bits and restart your shell by closing and opening a new window.

• Update pip using the following command: pip install -U pip (mentioned above)

• Install rust https://www.rust-lang.org/tools/install follow all the steps (takes about 4 minutes) and then close your shell window and open a new one. Make sure that the PATH environment variable includes Cargo's bin directory (%USERPROFILE%.cargo\bin).
