They cannot have OS- or Python version-specific “scripts” files. Python noarch packages must be “fully universal.” They cannot have OS- or Python version-specific dependencies. conda compiles pyc files at install time when prefix write permissions are guaranteed.

conda creates the Python entry points specified in the conda-build recipe, and.

conda maps the python-scripts directory to either /bin or /Scripts depending on platform,.

conda maps the site-packages directory to the correct location for the Python version in the environment,.

Files in a Python noarch package are linked into a prefix just like any other conda package, with the following additional features: These are much like universal Python wheels. Generic- and Python-Type Noarch/Universal Packages: Along with conda-build 2.1, a noarch/universal type for Python packages is officially supported. Rather than rolling back the download and extract operation for all packages, the single-package rollback prevents the need for having to re-download every package if an error is encountered. The distinction is that the rollback on error is limited to a single package. Progressive Fetch and Extract Transactions: Like package unlinking and linking, the download and extract phases of package handling have also been given transaction-like behavior. Moving forward, unforeseeable failures won’t be catastrophic. In some circumstances, OS file permissions cannot be fully known until an operation is attempted and fails, and conda itself is not without bugs. While we’ve implemented some pre-transaction checks (verifying package integrity for example), it’s impossible to anticipate every failure mechanism. If a failure occurs for any reason while conda is mutating files on disk, the environment will be returned its previous state. In some of the most severe examples, conda can appear to “uninstall itself.” With this release, the unlinking and linking of packages for an executed command is done in a single transaction. It has gleefully clobbered existing files mid-operation failures left environments completely broken. Unlink and Link Packages in a Single Transaction: In the past, conda hasn’t always been safe and defensive with its disk-mutating actions. To get the latest, just run conda update conda.

The 4.3 release series has several new features and substantial improvements. We’re excited to announce that conda 4.3 has been released for general availability.

PackagesNotFoundError: The following packages are not available from current channels: This is the full output with the error message: Collecting package metadata (current_repodata.json): doneĬollecting package metadata (repodata.json): done So the problem seems to be related with the older versions of python. I tried to change the version to 3.7, typing conda create -n myenv python=3.7 I used the command: conda create -n myenv python=3.4 and get the error: PackagesNotFoundError: The following packages are not available from current channels: I have miniconda 3 installation and want to create conda environment with Python 3.4.
